Starlink 1-27 Falcon 9 launched 60 Starlink satellites on May 9, 2021 on the Starlink 1-27 mission, which jumped ahead of the yet-to-fly Starlink 1-26 payload in flight order. Liftoff from Cape Canaveral SLC 40 took place at 06:42 UTC. First stage B1051.10 successfully landed on "Just Read the Instructions" about 631 km downrange, following entry and landing burns. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a roughly 259 x 284 km x 53 deg orbit. SpaceX has now orbited 1,625 Starlink satellites, though not all remain active or in orbit. B1051 is the first Falcon 9 booster to achieve 10 flights, a long-desired SpaceX goal. It first powered Crew Dragon’s DM-1 demonstration mission on March 2, 2019, then launched the RADARSAT Constellation Mission, SXM-7, and six Starlink missions. CZ-2C/Yaogan 30-08 China orbited its eighth set of Yaogan 30 triplet satellites on May 6, 2021 with Chang Zheng 2C launch vehicle Y47. The two stage rocket rose from Xichang Satellite Launch Center's LC 3 at 18:11 UTC. The satellite triplet was named Yaogan-30 Group 8. The "electromagnetic detection" satellites were inserted into roughly 600 km x 35 deg orbits. A rideshare satellite or experiment named Tianqi 12 was also orbited. The satellites may be formation flyers similar to the U.S. NOSS system, which perform a signals intelligence mission designed to monitor surface ship electronic emissions. It was the eighth launch for this constellation, all by CZ-2C rockets from Xichang LC 3, since September 29, 2017. Starlink 1-25 Falcon 9 added 60 more satellites to the Starlink constellation on May 4, 2021. Liftoff from KSC LC 39A took place at 19:01 UTC. First stage B1049.9 landed on "Of Course I Still Love You" about 630 km downrange, following entry and landing burns. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a low Earth orbit inclined 53 deg to the equator. B1049.9, the oldest operating Falcon 9 first stage, performed a static firing on the pad on May 3. It was the 13th Falcon 9 launch of the year, ten of which have been in-house Starlink missions. CZ-4C Yaogan 34 China's CZ-4C orbited Yaogan 34, an optical imaging spy satellite, from Jiuquan on April 30, 2021. Liftoff from 43/94 took place at 07:27 UTC. The three-stage rocket placed the SAST-built satellite into a roughly 1,100 km x 63.4 deg orbit. This was the first use of a 4 meter diameter payload fairing on a CZ-4C from Jiuquan. Starlink 1-24 Falcon 9 orbited 60 more Starlink satellites on April 29, 2021. Liftoff from Cape Canaveral SLC 40 took place at 03:44 UTC. First stage B1060.7 successfully landed on "Just Read the Instructions" about 615 km downrange, following entry and landing burns. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a roughly 250x280 km x 53 deg orbit. B1060 first boosted the GPS 3-3 mission during June 2020. It later boosted Turksat 5A and four Starlink missions. Its most recent flight was on March 24, 2021. It was the 12th Falcon 9 launch of the year. Nine of those were in-house Starlink missions. CZ-5B Begins China's Space Station China's 1.5-stage CZ-5B orbited the country's Tianhe core space station module from Wenchang on Hainan Island on April 29, 2021. Liftoff from Pad 101 took place at 03:23 UTC. The 22.5 tonne module, China's heaviest-ever orbiting payload, was boosted to a 171 x 382 km x 41.47 deg low Earth orbit in about eight minutes. It was the second CZ-5B flight. The 53.7 meter tall rocket rose on the combined 1,080 tonnes of thrust produced by 10 engines; two YF-77 gas generator engines on the 5-meter diameter LH2/LOX core and two YF-100 staged-combustion engines each on four 3.35 meter diameter kerosene/LOX strap-on boosters. The boosters separated about 173 seconds after liftoff. The core stage burned all the way to orbit. Vega VV18 Europe's Vega returned to flight with the successful launch of Arianespace Mission VV18 carrying the Airbus Pleiades Neo 3 Earth observation satellite from Kourou on April 29, 2021. Liftoff from ZLV took place at 01:50 UTC. Five secondary satellites from the U.S., Norway, and France also rode Vega to orbit. Vega's AVUM fourth stage fired its Ukrainian RD-843 engine four times during the mission. The first two placed the stage in a 628 km x 97.89 deg orbit for deployment of 920 kg Pleiades Neo 3. Two subsequent burns shifted the orbit to 613 km x 97.79 deg for deployment of the five small rideshare satellites. They included 16 kg Norsat 3 from Norway, Aurora Insight's Bravo satellite, two Spire CubeSats, and Tyvak Nano-Satellite System's ELO Alpha. It was Vega's first flight since the VV17 failure of November 17, 2020. During that flight, the AVUM stage tumbled out of control shortly after its first ignition because control cables had been improperly installed. Telemetry indicated that cables to two thrust vector control actuators had been inverted. Commands meant for one had been routed to the other, and vice versa. CZ-6 Launch China's fifth Chang Zheng 6 (CZ-6) orbited 9 microsatellites from Taiyuan Satellite Launch Center on April 27, 2021. Liftoff from LC 16 took place at 03:20 UTC. The rideshare mission included the Qilu 1 and Qilu 4 remote sensing satellites along with seven smaller satellites. The three-stage rocket lifted its payload into sun synchronous orbit. CZ-6, the first of China's all-new launch vehicle generation, debuted from the same site on September 19, 2015. A single 122 tonne thrust, staged-combustion cycle YF-100 LOX/kerosene engine powered the routhly 103 tonne, three-stage launch vehicle off of its launch pad. YF-100, China's first big LOX/kerosene engine, also powers the country's larger CZ-5 and CZ-7 launch vehicles. The first stage burned for about 155 seconds. The second stage, powered by a YF-115 staged combustion engine producing 18 tonnes of thrust, burned LOX/kerosene for about 290 seconds. At apogee, a small kick stage, powered by four 408 kgf thrust YF-85 hydrogen peroxide/kerosene engines, fired to circularize the orbit. CZ-6 is capable of lifting 1,080 kg into a 700 km sun synchronous orbit. It is integrated horizontally in a hangar. A large wheeled transporter/erector carries it to its flat launch pad and erects it shortly before launch. Delta 4 Heavy Launch A Delta 4 Heavy launched NROL-82, a classified satellite thought by some analysts to be a KH-11 spy satellite, into orbit from Vandenberg AFB on April 26, 2021. Liftoff from Space Launch Complex 6 took place at 20:47 UTC. The liquid hydrogen-fueled triple-core rocket headed south on a trajectory consistent with a likely sun synchronous low Earth orbit. It was the 13th Delta 4 Heavy launch and 12th success. Three more Delta 4 Heavy flights remain before the type is replaced by ULA's Vulcan. Soyuz OneWeb F6 A Russian Soyuz 2-1b/Fregat M added 36 Internet satellites to the growing OneWeb constellation on April 25, 2021. Liftoff from Vostochny Cosmodrome Site 1S took place at 22:14 UTC. The 3 hour 51 minute Starsem ST31 mission placed the 147.5 kg satellites into 450 km x 87.4 deg orbits. Total deployed payload mass was 5,310 kg. The payload deployment system addded another 500 kg of undeployed mass. Fregat's first burn placed the stage and payload into a low Earth transfer orbit. Its second burn, begun at apogee, circularized the orbit. Satellites deployed in nine groups, the last at T+3 hours 51 minutes, separated by Fregat ACS burns. Fregat performed an orbit lowering ACS burn about 4 hours 50 minutes after launch. It was the sixth OneWeb launch and the third since the company emerged from its 2020 bankruptcy. Those three OneWeb missions have launched from Vostochny. Crew 2 Falcon 9 launched the Crew 2 mission to the International Space Station from Kennedy Space Center on April 23, 2021. On board Crew Dragon C206 "Endeavour" were NASA astronauts Shane Kimbrough and Megan McArthur, European Space Agency astronaut Thomas Pesquet, and Japan Aerospace Exploration Agency astronaut Akihiko Hoshide, all space veterans. It was the second operational commercial crew flight, and the third crewed Crew Dragon mission. Liftoff from LC 39 Pad A took place at 09:49 UTC. Crew Dragon separated from the Falcon 9 second stage about 12 minutes after liftoff to begin its one day trip to dock with ISS. First stage B1061.2, which previously boosted the Crew 1 mission, fired its nine Merlin 1D engines for 2 min 36 sec, aiming the vehicle on a northeast trajectory off the eastern U.S. coast, before shutting down and separating. The stage performed entry and landing burns before landing on "Of Course I Still Love You" in the Atlantic Ocean. The second stage fired its single Merlin 1D Vacuum engine from T+2 min 47 sec until T+8 min 47 sec to reach a roughly 190 x 210 km x 51.6 deg low earth orbit. The first stage was static fired at LC 39A on April 17. "Endeavour" previously flew the Demo 2 crewed mission launched May 30, 2020. Soyuz MS-18 A Soyuz 2.1a orbited Soyuz MS-18, the year's first crewed space launch, from Baikonur Cosmodrome on April 9, 2021. Liftoff from Site 31 Pad 6 took place at 07:42 UTC. Russian cosmonauts Oleg Novitsky and Pyotr Dubrov and NASA astronaut Mark Vande Hei rode the spacecraft to orbit during its 8 minute 44 second ascent. Soyuz MS-18 then performed a three-orbit fast track ascent to the International Space Station. CZ-4B/Shiyan 6-03 China's Chang Zheng (Long March) 4B Y49 orbited Shiyan 6-03 from Taiyuan Satellite Launch Center on April 8, 2021. Liftoff from LC 9 took place at 23:01 UTC. The satellite was inserted into a roughly 1,000 km x 99.5 deg sun synchronous orbit. The mission of Shiyan Weixing 6-03 was described by offical new reports from China to be for "space environmental surveys and experiments on related technologies". The first two DFH-built Shiyan 6 satellites flew on CZ-2D rockets from Jiuquan to lower altitude orbits. Starlink 1-23 Falcon 9 orbited 60 more Starlink satellites on April 7, 2021. Liftoff from Cape Canaveral SLC 40 took place at 16:34 UTC, the first daylight launch since January 24. First stage B1058.7 successfully landed on "Of Course I Still Love You" about 615 km downrange, following entry and landing burns. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a roughly 270 km x 53 deg orbit. Once again, no prelaunch static firing was performed. B1058 first boosted the DM-2 Crew Dragon mission on May 30, 2020. It subsequently powered ANASIS 2, Starlinks 1-12 and 1-20, CRS-21 Cargo Dragon, and Transporter 1. Its most recent flight was on March 11, 2021. It was the tenth Falcon 9 launch of the year. Eight of those were in-house Starlink missions. Gaofen 12-02 China's CZ-4C orbited Gaofen 12-02, an Earth observation satellite, from Jiuquan satellite launch center on March 30, 2019. Liftoff from LC43/94 took place at 22:45 UTC. The three-stage CZ-4C (Y36) used its restartable third stage to place Gaofen 12-02 into a nearly 600 km x 97.8 deg sun synchronous orbit. The Shanghai Academy of Spaceflight Technology, China Aerospace Science and Technology Corp. developed Gaofen 12-02, one of a series of Earth observation satellites.

Soyuz Orbits OneWeb F5

Russia's Soyuz 2-1b/Fregat M orbited 36 more OneWeb Internet satellites from Vostochny Cosmodrome on March 25, 2021. Liftoff from Site 1S took place at 02:47 UTC. The 3 hour 10 minute Starsem ST30 mission placed the 36 satellites, each weighing 147.5 kg, into 450 km x 87.4 deg orbits. Total deployed payload mass was 5,310 kg. The payload deployment system addded another 500 kg of undeployed mass.

Fregat completed its first burn at 15 min 29 sec to reach a 150 x 427 km x 87.4 deg transfer orbit. Its second burn, begun at apogee 1 hour 13 minutes 40 seconds after liftoff, circularized the orbit. Satellites deployed in six groups of four during the subsequent roughly 1.5 hours, separated by Fregat ACS burns. Fregat performed an orbit lowering ACS burn about 3 hours 10 minutes after launch.

It was the fifth OneWeb launch. The first three took place before the company's March 2020 bankruptcy. OneWeb emerged from Chapter 11 during late November 2020 after it was sold to a group led by Bharti Global and the British government. The two subsequent OneWeb launches have now launched from Vostochny.

Starlink 1-22

Falcon 9 continued its recent torrid launch pace, orbiting 60 more Starlink satellites on March 24, 2021. Liftoff from Cape Canaveral SLC 40 took place at 08:28 UTC. First stage B1060.6 successfully landed on "Of Course I Still Love You" about 630 km downrange, following entry and landing burns. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a roughly 250 x 290 km x 53 deg orbit.

Once again, no prelaunch static firing was performed.

B1060 first boosted the GPS 3-3 mission on June 30, 2020. It subsequently powered Starlinks 1-11, -14, and -18 and Turksat 5A.

Electron 19

Rocket Lab's 19th Electron boosted six nanosatellites to orbit from Mahia Peninsula, New Zealand, on March 22, 2021. Liftoff from LC 1 took place at 22:30 UTC. After performing three burns to distribute the payloads into 550 km and 450 km orbits at 45 degree inclination, the rocket's Curie-powered third stage transitioned itself into a Photon pathfinder satellite mission named Pathstone. The overall mission was named "They Go Up So Fast".

Payloads included a 56 kg BlackSky Global satellite, 6U Centauri 3, 3U Myriota 7, 1U Veery Hatchling, The University of New South Wales’s Canberra Space M2 12U satellite for the Royal Australian Air Force, and 3U Gunsmoke-J for the U.S. Army Space and Missile Defense Command. Not including Photon/Pathstone, total payload mass was likely less than 90 kg.

Soyuz Rideshare Launch

Russia's Soyuz 2.1a/Fregat launched a 38-satellite rideshare mission into low Earth orbit from Baikonur Cosmodrome on March 22, 2021. Liftoff from Site 31 Pad 6 took place at 06:07 UTC, beginning a nearly five-hour mission that featured multiple Fregat burns to deploy satellites into three different orbits.

Soyuz was painted white and blue, the first Soyuz rocket painted white since 1975's Apollo Soyuz Test Mission. GK Launch Services, a subsidiary of Russia's government Roscosmos agency, coordinated the flight, which carried satellites from 18 countries.

South Korea's 500 kg CAS500-1, a remote sensing satellite, was the primary payload. It separated first into a roughly 499 km x 97.4 deg sun synchronous orbit about 64 minutes after liftoff. A set of four 100 kg GRUS-1 imaging satellites from Japan separated next, about 2 hours 50 minutes after launch, into a 592 km x 97.73 deg orbit. The remaining satellites were placed into a 550 km x 97.57 deg orbit at mission's end.

Starlink 1-21

SpaceX orbited 60 more Starlink satellites on March 14, 2021, completing the eighth Falcon 9 launch of the year. The launch put Starlink 1-21 into low Earth orbit after a 10:01 UTC liftoff from Kennedy Space Center LC 39A. First stage B1051.9 performed the first "ninth" Falcon 9 booster launch and landed successfully on "Of Course I Still Love You" about 630 km downrange, following entry and landing restart burns by up to three of the nine first stage Merlin 1D engines. The Falcon 9 second stage performed two burns during its one-hour mission to insert its 15.6 tonne payload into a roughly 250 x 290 km x 53 deg orbit.

The Starlink 1-21 campaign did not include a static firing on the pad, a practice that is becoming less common with previously flown Falcon 9 rockets.

B1051 boosted the first, unmanned Crew Dragon flight on March 2, 2019. It subsequently powered RCM from Vandenberg AFB and Starlinks 1-3, 6, 9, 13, and 16 and SXM-7 from Florida during 2019-2021. It was a reuse record for a complete liquid propellant first stage. At least two Space Shuttle booster segments flew 12 times, but SRBs were disassembled after each flight and not reflown in complete sets. Space Shuttle orbiter Discovery flew 39 times to orbit and back, disposing an External Tank each time.

It was the 90th Falcon 9 v1.2, and 110th Falcon 9, orbital launch attempt. Both of the payload fairing halves used on this mission had also prevously flown, during the January 24, 2021 Transporter 1 launch.

CZ-4C/Yaogan 31-04

China's CZ-4C number Y42 orbited the Yaogan 31-04 triplet from Jiuquan Satellite Launch Center in northwest China on March 13, 2021. Liftoff from LC 94/43 took place at about 02:20 UTC. The three-stage hypergolic propellant-fueled rocket boosted the satellites into roughly 1,100 km x 63.41 deg orbits. The satellites are thought to be formation flyers that triangulate the location of radio emitters, most likely used to track naval ships. Yaogan 31-03 was orbited during February, 2021 and Yaogan 31-02 during January 2021. Yaogan 31-01 was launched during 2018.

It was the fifth DF-5 based CZ launch of the year.

CZ-7A Succeeds

China's CZ-7A, an upgraded version of its previously-flown CZ-7 with a cryogenic third stage added, scored its first success during its second launch on March 11, 2021. The 3.5 stage rocket boosted the secret Xinjishu Yanzheng-6-02 (XJY-2-02) satellite, named Shiyan 9 (Experiment 9) upon reaching orbit, into a geosynchronous transfer orbit during a roughly one-half-hour mission. Liftoff from LC 201 at Wenchang Space Launch Center took place at 17:51 UTC. The third stage performed two burns, with the second taking place about 20-30 minutes after liftoff.

The first CZ-7A failed during its inaugural flight on March 16, 2020 due to a failure that appeared to occur during the early moments of the second stage burn. The true cause was only officially revealed after the second CZ-7A succeeded. One of the four first stage strap-on booster engines faltered after LOX cavitation began at the LOX tank outlet at T+168 seconds, 5 seconds before the YF-100 engines were supposed to shut down. When the combined first stage and boosters separated, they veered due to the unequal thrust, knocking the vehicle out of its proper attitude which led to an an explosion shortly after staging.

CZ-7A uses a 3.35 meter diameter core stage powered by two 122.5 tonne thrust YF-100 RP/LOX staged combustion engines. Four 2.25 meter diameter strap-on boosters, each powered by one YF-100, augment the core to produce a total of 734.1 tonnes (1.618 million pounds) of thrust at liftoff. Four 18 tonne thrust YF-115 RP/LOX staged combustion engines power the 3.35 meter diameter second stage. Two YF-75 engines produce a combined 16.3 tonnes thrust to power the third, 21 tonne LH2/LOX stage. Two previous, successful CZ-7 launches, with no cryogenic third stage, took place in 2016 and 2017.

Starlink 1-20

SpaceX orbited 60 more Starlink satellites on March 11, 2021. The 110th Falcon 9 launch put Starlink 1-20 into low Earth orbit after a 08:13 UTC liftoff from Cape Canaveral SLC 40. First stage B1058.6 performed its sixth launch and landed successfully on "Just Read the Instructions" some 630 km downrange, following entry and landing restart burns using three of the nine first stage Merlin 1D engines. The Falcon 9 second stage performed two burns to insert its 15.6 tonne payload into a roughly 250 x 290 km x 53 deg orbit.

The Starlink 1-20 campaign included a full vehicle propellant loading rehearsal and a static test firing of the first stage at SLC 40 on March 8.

B1058 boosted the first crewed Dragon 2 mission on May 30, 2020. It subsequently powered ANASIS 2, Starlink 1-12, the CRS-21 Dragon 2 cargo mission, and Transporter 1, all from Florida during 2020-21. All of its landings have been on drone ships downrange.

Starlink 1-17

On March 4, 2021, Falcon 9 v1.2 stack number 108 finally orbited Starlink 1-17 after weeks of delay that saw Starlinks 1-18 and 1-19 skip ahead of it in launch order. Liftoff from KSC LC 39A took place at 08:24:54 UTC. First stage B1049.8 performed its eighth launch and landed successfully on Of Course I Still Love You some 630 km downrange. The Falcon 9 second stage performed two burns to insert its 15.6 tonne payload into a roughly 250 x 290 km x 53 deg orbit.

The first stage recovery was an improvement on the previous, February 16, Starlink 1-19 flight result, which suffered a premature Merlin 1D engine shutdown during the final seconds of its B1059.6 first stage ascent, leading to the loss of the stage during reentry. SpaceX subsequently announced that the cause of the loss was a burn-through of one of the flexible boots located where the engine penetrates the base of the stage. The burn-through caused overheating in the engine compartment, which caused the engine shut down and appeared to result in a fire at the end of the attempted entry burn. Meanwhile, that Starlink's ascent to orbit mission was successful.

The Starlink 1-17 campaign began with an aborted static fire attempt on January 29, 2021. A static firing was accomplished on January 31, but unspecified problems discovered at that time led to an extended stand-down. The vehicle was finally rolled out for a second static firing at LC 39A on February 24.  A March 1 launch attempt was aborted at T-1 minute 24 seconds for unspecified reasons.

B1049 first flew on September 10, 2018 when it boosted the Telstar 18V mission. It launched Iridium NEXT 8 on January 11, 2019, then boosted Starlinks 0.9, 1-2, 1-7, 1-10, and 1-15 during 2019-2020. All of its landings have been on drone ships downrange.

Arktika 1

Russia's Soyuz 2-1b/Fregat orbited Arktika 1, the first of a new type of Arctic region weather satellite, into a 12-hour elliptical Molniya orbit from Baikonur Cosmodrome on February 28, 2021. Liftoff from Site 31 Pad 6 took place at 06:55 UTC. The Fregat upper stage performed three burns during a multiple-hour mission to boost the 2.1 tonne Arktika M type satellite into its orbit.

Several more Arktika launches are planned, aiming to create a constellation of satellites to monitor Russia's Arctic regions.

PSLV C51

India's third PSLV-DL variant orbited Brazil's Amazonia 1 Earth observation satellite along with 18 microsatellites from Satish Dhawan Space Center at Sriharikota on February 28, 2021. Liftoff from the First Launch Pad took place at 04:54 UTC. PSLV-DL uses two PS0M-XL strap-on solid motors.

The 4.5 stage rocket, performing mission number C51, fired its strap-on motors for 1 minute 10 seconds, its S139 first stage solid motor for 1 minute 50 seconds, its Vikas-powered UDMH/N2O4 fueled second stage for 2 minutes 33 seconds, and its PS3 solid motor third stage for 3 minutes 52 seconds (including coast) to boost its MMH/MON fueled fourth stage on a coast toward apogee where its twin L-2-5 engines ignited to provide the orbital insertion. The 700 kg satellite separated into a roughly 750 km x 98.51 deg sun synchronous orbit. Two more PS4 fourth stage engine firings then lowered the orbit to roughly 500 x 560 km x 97.38 deg for the deployment of the 18 microsatellites.

CZ-4C/Yaogan 31-03

China's CZ-4C, tail number Y32, orbited the Yaogan 31-03 triplet from Jiuquan Satellite Launch Center in northwest China on February 24, 2021. Liftoff from LC 94/43 took place at 02:22 UTC. The three-stage hypergolic propellant-fueled rocket boosted the satellites into roughly 1,100 km x 63.41 deg orbits. The satellites are thought to be formation flyers that triangulate the location of radio emitters, most likely used to track naval ships. Yaogan 31-02 was orbited in January 2021. Yaogan 31-01 was launched during 2018.

It was the fourth DF-5 based CZ launch of the year.


Antares/Cygnus NG-15

The 14th Antares launch vehicle - and fourth upgraded Antares 230+ - boosted Northrop Grumman's Cygnus NG-15 cargo spacecraft into orbit from Wallops Island, Virginia on February 20, 2021. Liftoff from Pad 0A took place at 07:36:50 UTC.

Cygnus NG-15 was the 12th enhanced Cygnus with a stretched Thales Alenia Space cargo module and the ninth to fly on Antares. Atlas 5 rockets orbited the other three. NG-15 probably weighed about 7,700 kg at launch, including 3,810 kg of cargo for the International Space Station. Cygnus NG-15 was named in honor of NASA mathematician Katherine Johnson.

The RD-181 engines produced 392 tonnes of thrust to power the nearly 293 tonne rocket off its pad. The Ukrainian-built first stage burned for about 198 seconds. After first stage shutdown, the upper composite separated at T+204 seconds and coasted upward. The shroud and interstage adapter separated at 234 and 239 seconds, respectively. At about T+247 seconds the Northrop Grumman Castor 30XL second stage motor ignited to produce an average of about 51 tonnes of thrust during its roughly 167 second burn. Cygnus separated at T+532 seconds into a 180 x 360 km x 51.66 deg orbit.

Like Antares 230, the Antares 230+ first stage is powered by two Energomash RD-181 engines in place of the AJ-26 engines that powered the first five Antares flights. Antares 230+ uses a stronger first stage structure to allow full-thrust operation through much of its burn. In addition, unneeded dry mass was stripped from the first and second stages and a single-piece interstage was implemented.

Starlink 1-19

SpaceX orbited another group of 60 Starlink satellites from Cape Canaveral on February 16, 2020. Falcon 9 v1.2 liftoff took place at 03:59 UTC from Space Launch Complex 40. First stage B1059.6, performing its sixth flight, boosted the flight during its first 2 min 32 sec. After separating, the stage flipped and performed a three-engine entry burn, but flames were visible streaming from the base of the stage after the end of the burn. The stage did not survive to perform its planned landing on Of Course I Still Love You parked about 630 km downrange.

The second stage fired from 2:44 to 8:47 to reach a parking orbit. It restarted at 45:31 for one second to reach its roughly 250 x 280 km x 53 deg insertion orbit. The 15.6 tonne payload separated at T+64:28.

1059.6 previously boosted CRS-19, CRS-20, the Starlink 1-8 rideshare mission, SAOCOM-1B, and NROL-108 during 2019-2020. It was the first loss of a first stage in 11 months and follows 24 consecutive first stage recoveries.

Progress MS-16

Russia's Soyuz 2.1a launched Progress MS-16 from Baikonur Site 31 Pad 6 on February 15, 2021. Liftoff took place at 04:45 UTC. The robot cargo hauler spacecraft ascended to a two-day, 33-orbit ascent to the International Space Station. Progress MS-16 carried about 2,460 kg of cargo, including 600 kg of propellant, 40.5 kg of pressurized gases, 420 kg of drinking water, and 1,400 kg of dry cargo. The cargo included a repair kit for a leak on the Zvezda service module.

It was the second Russian and R-7 launch of the year.

CZ-3B TJSW 6

China's CZ-3B/Enhanced orbited the sixth Tongxin Jishu Shiyan Weixing (TJSW 6) communications engineering test satellite from Xichang Satellite Launch Center on February 4, 2019. Liftoff from LC 3 took place at 15:36 UTC. The launch vehicle's LH2/LOX fueled third stage fired twice to send TJSW 6 into geosynchronous transfer orbit. TJSW 6 may be a SIGINT, or a communications satellite, or provide early warning capability, or, maybe all or none of the above.


Starlink 1-18

A Falcon 9 v1.2 boosted the 18th operational group of 60 Starlink internet satellites from Kennedy Space Center, Florida on February 4, 2021. Liftoff from Space Launch Complex 40 took place at 06:19 UTC. This flight jumped ahead in sequence after the Starlink 1-17 launch campaign was delayed. The latter Falcon 9 stood at KSC LC 39A while the Starlink 1-18 liftoff took place a few miles down the coast. Falcon 9's second stage performed two burns to reach the low Earth deployment orbit. The Starlinks separated at about 65 minutes after liftoff. They will ultimately move themselves to 550 km operational orbits. Total deployed payload mass was about 15,600 kg.

First stage B1060.5, on its fifth flight, fired for 2:33 before separating, flipping, and performing entry and landing burns to land on "Of Course I Still Love You" about 630 km downrange. No prelaunch static test fire was performed. B1060 previously boosted GPS 3-3, Starlinks 1-11 and 1-14, and Turksat 5A during 2020-21. Turnaround from the Turksat 5A mission was only 27 days.

The second stage fired for 6 minutes 6 seconds to reach an elliptical parking orbit. It restarted at T+45 minutes 55 seconds for only one second to raise the orbit perigee.

Soyuz 2-1b Orbits Lotos S1 805

A Soyuz 2-1b launch vehicle orbited Russia's Lotos S1 No. 805 signals intelligence satellite from Plesetsk Cosmodrome on February 2, 2021. Liftoff of the 2.5 stage rocket from Site 43/4 took place at 20:45 UTC. Lotos S1 805, a 6 tonne satellite built by TsSKB Progress using a Yantar type bus, was inserted into an initial 240 x 899 km x 67.14 deg orbit. The satellite will later raise itself into a 900 km circular operational orbit.

The Arsenal bureau developed the ELINT payload carried by Lotos S1 805.

It was Russia's first launch of 2021.

SQX-1 Fails (Updated March 7, 2021)

China's Beijing Interstellar Glory Space Technology Ltd. (iSpace) suffered a failure of its SQX-1 (Hyperbola-1) launch vehicle from Jiuquan Satellite Launch Center on February 1, 2021. Liftoff took place at 08:15 UTC. The failure occurred shortly after liftoff. After rising cleanly from its launch stand, the rocket began a pitch program, but then, possibly while accelerating through MaxQ, something happened to the front part of the rocket. The vehicle disentegrated soon after. No payload had been announced for the flight. It was the second SQX-1 orbital attempt, following an inaugural success on July 25, 2019.

On March 1, iSpace announced that an investigation had determined that a piece of foam insulation, which was designed to fall away after liftoff, had struck and retarded one of the four steering grid fins located at the base of the first stage. The foam piece later fell away, causing the grid fin to move suddenly, which caused the rocket to veer away from its desired angle of attack.

The four-stage rocket, possibly based on solid rocket motors from DF-11 or DF-15 ballistic missiles, was 24 meters long, an increase of 3.2 meters from the inaugual version. It retained its 1.4 meter maximum diameter. Liftoff thrust was 42 tonnes. Gross liftoff weight likely exceeded 31 tonnes. Payload capability was listed at 300 kg to a sun synchronous orbit, 40 kg more than for the first SQX-1.

During 2018, iSpace conducted two suborbital tests as part of its development effort. One, which was 8.4 meters long, weighed 4.6 tonnes, and used standard fins, was named SQX-1S. The other, which used four grid fins for atmospheric steering, was named SQX-1Z.

Yaogan 31 Launch

China's CZ-4C, tail number Y31, orbited the Yaogan 31-02 triplet from Jiuquan Satellite Launch Center in northwest China on January 29, 2021. Liftoff from LC 94/43 took place at 04:47 UTC. The three-stage hypergolic propellant-fueled rocket likely boosted the satellites toward a 1,100 km x 63.4 deg orbit. The satellites are thought to be formation flyers that triangulate the location of radio emitters, most likely used to track naval ships. Yaogan 31-02 entered an orbital plane that was 48 degrees east of the Yaogan 31-01 group that was launched in 2018.

It was the second DF-5 based CZ launch of the year.

Falcon 9 Transporter 1

A Falcon 9 v1.2 boosted a record 143 satellites into orbit from Cape Canaveral, Florida on January 24, 2021. Liftoff from SLC 40 took place at 15:00 UTC. It was the second near-polar orbit launch by a Falcon 9 from the Cape during the past year. Prior to these flights, it had been 51 years since such a southbound launch had flown from Florida. Falcon 9 doglegged from south-southeast to south-southwest during its ascent as it flew down the Florida coast.

After firing for 2 minutes 28 seconds during ascent, first stage B1058.5, on its fifth flight, performed entry and landing burns to land on the "Of Course I Still Love You" drone ship down range.

The second stage performed one, 5 minute 55 second burn to reach a roughly 230 x 540 km parking orbit. The stage flew over Cuba and Panama and Antarctica before performing a 2-second restart over the Indian Ocean about 54 minutes 35 seconds after liftoff to reach a roughly 540 km sun synchronous orbit. A more than 30-minute long period of satellite deployments then took place. Payload included 133 commercial and government CubeSats, microsats, and orbital transfer vehicles, along with 10 Starlink satellites.

The first stage prevously launched the Demo 2 Crew Dragon mission, ANASIS 2, Starlink 1-12, and the CRS-21 Dragon 2 cargo mission, all during 2020 from Florida. The stage was not static test fired prior to this launch.

Starlink 1-16

A Falcon 9 v1.2 boosted the 16th operational group of 60 Starlink internet satellites from Kennedy Space Center, Florida on January 20, 2021. Liftoff from Launch Complex 39 Pad A took place at 13:02 UTC. The Falcon 9 second stage performed two burns to reach the low Earth deployment orbit. The Starlinks separated at about 64 minutes after liftoff. They will ultimately move themselves to 550 km operational orbits. Total deployed payload mass was about 15,600 kg.

First stage B1051.8, on its fleet-leading eighth flight, fired for 2:32 before separating, flipping, and performing entry and landing burns to land on "Just Read the Instructions" some 633 km downrange. No prelaunch static test fire was performed. B1051 previously boosted the Dragon 2 Demo-1 mission in March, 2019, followed by the RADARSAT Constellation Mission from Vandenberg AFB during June 2019, Starlinks 1-F3, 1-F6, 1-F9, and 1-F13 during 2020, and SXM-7 in December, 2020.

The second stage fired for 6 minutes 2 seconds to reach an elliptical parking orbit. It restarted at T+45 minutes 35 seconds for only one second to raise the orbit perigee.

Electron Mystery Satellite

Rocket Lab’s 18th Electron orbited a mysterious satellite built by Germany's OHB from New Zealand's Mahia Peninsula LC 1 on January 20, 2021. The three-stage Electron/Curie rocket, named "Another One Leaves the Crust", lifted off at 07:26 UTC, beginning a one-hour mission that lofted the satellite into a low Earth orbit. OHB refused to identify the satellite owner, and only revealed the "GMS-T" satellite name after the launch.

The first stage fired for about 2 minutes 30 seconds and the second for about 6 minutes 9 seconds to insert the storable propellant Curie upper stage and payload into an ellipical transfer oribt. Curie coasted to apogee where, beginning at T+66:07, it fired for 3 minutes 21 seconds to circularize the orbit. The satellite separated about one 70 minutes after liftoff.

CZ-3B/Tiantong 1-03

China's Chang Zheng (Long March) 3B/E orbited the third Tiantong 1 mobile communications satellite (Tiantong 1-03) from Xichang Satellite Launch Center on January 19, 2021. Liftoff from Launch Complex 2 took place at 16:25 UTC. The satellite, which may have weighed 5 tonnes or more, was inserted into a geosynchronous transfer orbit after two burns by the rocket's liquid hydrogen fueled upper stage.

After it raises itself to geostationary orbit, the satellite will provide mobile communications coverage to China, the Middle East, Africa, and the Indian and Pacific Oceans. Tiantong 1-03 provides S-band mobile communications services for China SatCom. It was developed by the Chinese Academy of Space Technology. The first Tiantong 1 was launched on August 5, 2016, followed by the second on November 12, 2020.

LauncherOne Success

Virgin Orbit's LauncherOne reached orbit for the first time on January 17, 2021 after a 19:39 UTC drop release from Virgin Orbit's Cosmic Girl 747 carrier aircraft off the California coast. Ten NASA cubesats rode the innovative, 25.855 tonne rocket to orbit during its Launch Demo 2 flight. The success came about eight months after the first LauncherOne failed shortly after its LOX/Kerosene NewtonThree engine ignited.

This time, the 21.3 meter long, two-stage rocket's first stage engine ignited cleanly and completed its 33.34 tonne-thrust, roughly 3-minute burn. The second stage NewtonFour engine then provided 2.27 tonnes of thrust for about 5 minutes 56 seconds to reach a transfer orbit. After a coast to apogee, NewtonFour restarted for roughly 4.3 seconds at about T+55 minutes 46 seconds to reach its 492 x 518 km x 60.7 deg insertion orbit. After the Cubesats separated, the second stage performed a final orbit lowering burn or maneuver, ending up in a 415 x 504 km orbit. The cubesats were part of the 20th Educational Launch of NanoSatellites (ELaNa 20) mission. Total deployed payload mass was 23.86 kg.

It was the first successful orbital launch by a liquid-fueled, air-drop-launched rocket.

Turksat 5A

A SpaceX Falcon 9 v1.2 boosted the Turksat 5A communications satellite into an elliptical, likely supersynchronous, transfer orbit from Cape Canaveral, Florida on January 8, 2021. Liftoff from Space Launch Complex 40 took place at 02:15 UTC. The Falcon 9 second stage fired twice to loft the 3.5 tonne Airbus Defense and Space E3000EOR series satellite into its insertion orbit. Turksat 5A deployed 33 min 4 sec after liftoff.

First stage B1060.4, flying for the fourth time, fired for 2 min 34 sec before flipping to perform entry and landing burns before landing on the Just Read the Instructions droneship floating 673 km downrange in the Atlantic Ocean. It will be the 70th successful stage recovery if B1060.4 returns safely to port. The stage previously boosted the GPS 3-3 and Starlink 1-11 and 1-14 missions during 2020. The second stage fired from 2 min 38 sec to 8 min 02 sec to reach a parking orbit, then restarted at T+26 min 51 sec for a 70 sec-long insertion burn. The previously-flown fairing halves separated at T+3 min 37 sec. Retreival ships Ms. Tree and Ms. Chief waited 786 km downrange to attempt recovery.

Soyuz Orbits CSO 2

Russia's Soyuz 2.1a/Fregat performed the Arianespace VS25 mission from Kourou Space Center on December 29, 2020, carrying the CSO 2 French defense imaging satellite into sun synchronous orbit. The satellite will peform high resolution imaging in the visible and infrared bands.

Liftoff from the Soyuz launch complex (ELS) took place at 16:42 UTC. The 2.5 stage Soyuz completed its ascent 8 min 49 sec after liftoff. About one minute later, Fregat began the first of its four planned burns. The first placed the vehicle into an elliptical parking orbit. Near first apogee Fregat ignited for its second burn beginning at T+54 minutes 7 seconds after liftoff. This burn circularized the orbit at about 480 km with a 97.3 degree inclination. The 3,562kg Airbus Defense and Space/Thales Alenia Space satellite separated at T+59:37. Fregat performed two subsequent maneuvering burns to separate from CSO 2 and to lower the orbit of the spent stage.

The liftoff was delayed one day by unacceptable high altitude winds. It was the 15th and final R-7 based launch of 2020, completing the 64th year of flight by Korolev's trailblazing rocket.

CZ-4C/Yaogan 33

China's CZ-4C number Y-35 orbited the Yaogan 33 synthetic aperture radar satellite and a secondary payload from the Jiuquan Satellite Launch Center on December 28, 2020. Liftoff from Site 43 Pad 94 took place at 15:44 UTC. The CZ-4C restartable third stage fired twice to reach a sun synchronous low earth orbit, then fired again to lower the orbit of the spent stage for future reentry.

A previous Yaogan 33 failed to reach orbit during a May 22, 2019 launch attempt from Taiyuan Satellite Launch Center. The launch reportedly failed due to structural resonance between the third stage and its relatively heavy Yaogan 33 remote sensing payload, possibly during the reignition of the third stage. Yaogan 29, believed to be the first of this type of SAR satellite, was orbited from Taiyuan on November 26, 2015. Both previous launches were performed by CZ-4C launch vehicles, but this flight was the first from Jiuquan for this payload type.

It was the 25th DF-5 based CZ launch of 2020, matching Falcon 9's world-leading orbital launch total, though the CZ-2,3,4 family suffered one launch failure during the year versus no failures for Falcon 9. The launch did cement China's first place orbital launch standing among the world's nations for 2020, with 35 successes in 39 attempts.

CZ-8 Inaugural

China debuted its CZ-8 medium-lift launch vehicle on December 22, 2020. The 2.5-stage, 50.3 meter tall, 356 tonne rocket boosted five satellites into sun synchronous orbit after an 04:37 UTC liftoff from Wenchang Spacecraft Launch Site on China's Hainan island. The primary payload was 3 tonne XJY-7, a classified remote sensing technology test satellite. Hisea 1, a 180 kg C-band sythetic aperture radar satellite was also orbited, along with three nanoosatellites.

CZ-8 uses the CZ-7 3.35 meter diameter core with its twin YF-100 staged combustion kerosene/LOX engines, but augmented by only two of the 2.25 meter diameter liquid strap-on boosters, each using a single YF-100, rather than CZ-7's four. The CZ-7 second stage is not used. Instead, a 3 meter diameter liquid hydrogen/LOX dual YF-75-powered upper stage that is used by CZ-3A/B and CZ-7A serves as a second stage. CZ-8 is designed to lift 4.5 tonnes to a 700 km sun synchronous orbit, or 2.5 tonnes to geosynchronous transfer orbit, slightly less than existing CZ-3A capability. This launch achieved a roughly 510 km x 97.4 deg sun synchronous orbit.

On this flight the YF-100 engines throttled down for the first time, to 77.5% at Max-Q. The two boosters shut down and separated at T+172 seconds. The core burned until T+208 seconds. The payload fairing separated at T+215 seconds, shortly after second stage ignition. Stage 2 shut down at T+479 seconds to reach a temporary ascent trajectory. The stage performed a second burn from t+885 to 1030 seconds to reach its insertion orbit.

Falcon 9 Orbits NROL 108

SpaceX’s Falcon 9 orbited NROL 108, a secret payload for the National Reconnaissance Office, from Kennedy Space Center Launch Complex 39 Pad A on December 19, 2020. Liftoff took place at 14:00 UTC, following an aborted attempt two days earlier caused by a slightly high second stage LOX pressure reading.

Falcon 9 headed on a northeast azimuth that some analysts believed indicated a 50-52 deg inclination low Earth orbit similar to NROL 76, which was launched by a Falcon 9 on May 1, 2017. No coverage was provided of the second stage performance as the flight entered a press blackout. The NRO announced a successful launch several hours after the liftoff.

After completing its short, 2 min 18 sec ascent burn, first stage B1059.5, on its fifth flight, flipped and performed a 3-engine boostback burn. It flipped again before performing a 3-engine entry burn, following by a single engine landing burn. The stage landed at Cape Canaveral Landing Zone 1 about 8 minutes 15 seconds after liftoff. It was the 69th successful first or booster stage landing and recovery. B1059 previously boosted the CRS-19 and 20 Dragon missions, Starlink 1-8, and SAOCOM 1B during 2019-20.

B1059.5 Lands at Cape Canaveral LZ-1

The second stage was expected to perform a deorbit burn sometime after satellite separation. A targeted zone for the stage to fall was listed in the Pacific Ocean near the equator south of Baja California.

It was the 25th Falcon 9 orbital flight of the year, a record for the rocket. One additional Falcon 9 performed the suborbital Crew Dragon In-Flight Abort test during the year. It was also the 30th orbital launch from Cape Canaveral and KSC during 2020, a number not seen since 1966 when 31 orbital attempts were made, but only 29 of those 1966 attempts made orbit while all 30 flights in 2020 succeeded.

Soyuz Orbits OneWeb 75-110

Russia's Soyuz 2-1b/Fregat M orbited 36 more OneWeb Internet satellites into low Earth orbit from Vostochny Cosmodrome on December 18, 2020. Liftoff from Site 1S took place at 12:26 UTC. The 3 hour 10 minute Starsem ST29 mission placed the 36 satellites, each weighing 147.5 kg, into 440 km x 87.4 deg orbits. Total deployed payload mass was 5,310 kg. The payload deployment system addded another 500 kg of undeployed mass.

Fregat completed its first burn at 15 min 29 sec to reach a 150 x 427 km x 87.4 deg transfer orbit. Its second burn, begun at apogee 1 hour 13 minutes 40 seconds after liftoff, circularized the orbit. Satellites deployed in six groups of four during the subsequent roughly 1.5 hours, separated by Fregat ACS burns. Fregat performed a deorbit burn about 3 hours after launch.

It was the first OneWeb launch since March 21, 2020. The company declared bankruptcy soon after that launch. It emerged from Chapter 11 during late November after it was sold to a group led by Bharti Global and the British government.

The flight was the 100th orbital launch success of 2020.

PSLV/CMS 1

India's PSLV-XL orbited the CMS 1 government communications satellite from Sriharikota on December 17, 2020. Liftoff of the C50 mission from the Second Launch Pad at Satish Dhawan Space Center took place at 10:11 UTC. The 4.5-stage rocket boosted the 1,410 kg satellite into a 284 x 20,650 km x 17.86 degree subsynchronous transfer orbit.

CMS 1, previously known as GSAT 12R, will raise itself to geostationary orbit to replace GSAT 12. It will serve India and nearby islands.

Four of the PSOM-XL strap-on solid motors ignited with the PS1 solid motor first stage at liftoff. The other two ignited at T+25 seconds. The PSOMs separated in pairs at T+69, 70, and 92 seconds. First stage PS1 cutoff at T+109 seconds and the hypergolic liquid fueled PS2 second stage ignited one second later for its 2 min 34 sec burn. The payload fairing separated at T+3 min 23 sec during the burn. Solid fuel HPS3 fired next, for 6 min 14 sec. The PS4 monomethyl hydrazine fueled fourth stage then fired for 8 min 35 sec to reach the insertion orbit. CMS 1 separated at T+20 min 11 sec.

Astra Rocket Falls Short of Orbit

Astra's Rocket 3.2, a small two-stage LOX/Kerosene fueled rocket, failed to reach orbit during its second orbital attempt from Alaska's Kodiak Launch Pad 3B on December 15, 2020, after a 20:55UTC liftoff. The mission proceeded past staging through most of the second stage burn, but the stage shut down about 12-15 seconds short of the burn time needed to achieve its planned 380 km x 98.1 deg orbit. The cause was improper propellant mixture ratio, which caused the kerosene to be depleted while significant LOX remained.

The company's earlier, March 2020 attempts to fly Rocket 3.0 for the Darpa Challenge failed to produce a launch after multiple countdowns. A final, March 23 attempt ended with a prelaunch failure that destroyed the rocket and started a fire at the launch site. A September 12, 2020 orbital launch attempt by Rocket 3.1 failed about 20 seconds into flight due to oscillations introduced by the guidance system.

Astra Rocket stands 11.6 meters tall and is 1.32 meters diameter. Its probably weighs 10-11 tonnes at liftoff, rising on 14.275 tonnes of thrust provided by its five battery-powered Delphin rocket engines . It uses an "ultra-low-cost" metal structure. Although designed to place at least 100 kg into a presumably near-polar low Earth orbit, Astra 3.2 carried no payload during this orbital flight test.

Astra performed two suborbital test launches during 2018 from Kodiak, Alaska, using only live first stages. The first, an Astra Rocket 1.0 flown from Launch Pad 2 on July 21, 2018, reportedly failed about 60 seconds after liftoff. The second, an Astra Rocket 2.0, failed shortly after its November 29, 2018 attempt from the same pad.

Electron 17

Rocket Lab’s 17th Electron orbited the StriX-a sythetic aperature radar (SAR) imaging satellite from New Zealand's Mahia Peninsula LC 1 on December 15, 2020. The three-stage Electron/Curie rocket, named "Owl's Night Begins", lifted off at 10:09 UTC, beginning a one-hour mission that lofted the 150 kg satellite into a routhly 495 x 513 km x 97.37 deg synchronous orbit.

The first stage fired for about 2 minutes 27 seconds and the second for about 6 minutes 12 seconds to insert the storable propellant Curie upper stage and payload into an ellipical transfer oribt. Curie coasted to a 500 km apogee where, beginning at T+52:28, it fired for 1 minute 54 seconds to circularize the orbit. The satellite separated about one hour after liftoff.

StriX-a is the first of a planned Synspective constellation of more than 30 small SAR satellites designed to scan cities across Asia.

It was the seventh Electron launch and sixth success of 2020.

Angara A5 Test

Russia's Angara A5 performed its second test flight on December 14, 2020. The 773 tonne 3.5 stage rocket lifted off from Site 35/1 at 05:50 UTC, rising on 980 tonnes of thrust from its five Energomash RD-191 kerosene/LOX engines. It carried a dummy payload mass simulator named IPM, aimed toward a near-geosynchronous orbit during a nine-hour mission that included five burns by the Briz-M upper stage. After achieving its target orbit, Briz-M performed its fifth burn to raise itself and its dummy payload to a higher, "burial" orbit.

It was the first Angara A5 flight since the first on December 23, 2014. The long delay was caused in part by a shift in URM-1 manufacturing from Krunichev near Moscow to PO Polyot neaq Omsk. The second flight was essentially a repeat of the first, part of the process of certifying the new rocket to replace long-lived Proton. It will eventually fly from Vostochny Cosmodrome.

Angara A5 consists of five 2.9 meter diameter URM-1 (Universal Rocket Module) units clustered to form a core stage surrounded by four booster stages. The core first stage is topped by a 3.6 meter diameter URM-2 second stage and a Briz M third stage. Each URM-1 is powered by a single chamber, 196 tonne thrust RD-191 staged combustion kerosene/LOX engine. RD-191 is derived from the four-chamber Energomash RD-171 engine that powered the Zenit launcher. URM-2 is powered by a 30 tonne thrust LOX/kerosene RD-0124 engine. This staged-combustion engine was developed to power the upgraded Soyuz-2 third stage. The Briz-M hypergolic propellant third stage has flown for years atop Proton-M boosters.

After liftoff, the core throttled down while the four strap-on boosters burned at full thrust. The boosters separated about 3.5 minutes into the flight. The core stage separated less than two minutes later. After the second stage burned out at about the 12 minute 26 second mark (it fell into the western Pacific Ocean), the first Briz-M burn inserted the stage and payload into a low earth orbit with a 63 deg inclination. Subsequent burns moved the vehicle into an initial elliptical transfer orbit. The fourth burn circularized the orbit at geosynchronous altitude.

SXM-7

SpaceX's Falcon 9 rocket reached orbit for the 100th time on December 13, 2020 when it boosted the SXM-7 communications satellite into a subsynchronous transfer orbit from Cape Canaveral, Florida. Liftoff from Space Launch Complex 40 took place at 17:30 UTC. The second stage performed two burns to accelerate the roughly 7 tonne satellite into its insertion orbit for customer Sirius XM . Meanwhile, first stage B1051.7, flying for the seventh time, landed on the Just Read the Instructions drone ship after completing its portion of the ascent.

B1051 had previously boosted Crew Dragon Demo 1, RADARSAT Constellation, and four Starlink missions, during 2019-20. One of the payload fairing halves had also flown before, during the ANASIS 2 mission in July 2020.

The first stage was static fired at SLC 40 on December 7. A December 11 launch attempt was aborted with less than one minute remaining in the countdown due to a ground equipment issue.

SXM-7 was inserted into a roughly 249 x 19,515 km x 27 deg initial subsynchronous transfer orbit from which it will gradually raise itself to geosynchronous orbit at 35,786 km altitude.

Delta 4 Heavy Launch

A United Launch Alliance Delta 4 Heavy boosted the National Reconnaissance Office (NRO) L-44 mission (NROL-44) into what was likely a geosynchronous orbit from Cape Canaveral, Florida on December 11, 2020. Liftoff from Space Launch Complex 37B took place at 01:09 UTC. ULA's success annoucement came more than 6 hours later, consistent with the time needed for the Delta 4 upper stage to perform a three-burn geosynchronous insertion mission. Analysts believe the payload is an ADVANCED ORION (Mentor) SIGINT satellite.

Delta 385 experienced a long, challenging launch campaign. It was erected at the pad during November, 2019 for propellant loading testing during January, 2020. This allowed ULA crews to shift back to Atlas missions during the ensuing months. After the NROL-44 payload was stacked, the rocket experienced a series of scrubs and aborts. An August 27 attempt was stopped by pneumatic issues during fueling. An August 29 countdown ended in an abort at T-3 seconds that shut down one of the three RS-68A engines. A pad pressure regulator failure was the cause. ULA replaced all three regulators during the ensuing weeks. A September 30 countdown ended in another abort, this time at T-7 seconds just before the engines started. This abort was caused by a faulty sensor.

Pad swing arm hydraulic issues had appeared during the September 30 countdown, so ULA decided to spend several weeks resolving that problem before performing the final, successful countdown.

It was the 12th Delta 4 Heavy launch. Four more Delta 4 Heavy launches remain on the schedule with the last expected during 2024.

CZ-11/GECAM

China's four-stage solid fuel CZ-11 launched the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) into low earth orbit from Xichang Satellite Launch Center on December 9, 2020. It was the second CZ-11 launch from Xichang. Liftoff took place at 20:14 UTC.

GECAM is a two-satellite mission designed to measure the "electromagnetic counterparts of gravitational waves, high-energy radiation from fast radio bursts, various gamma-ray bursts, and magnetar flares", according to the National Space Science Center under the Chinese Academy of Sciences (CAS).

It was the 11th known CZ-11 flight since the type premiered on September 25, 2015. The 58 tonne rocket may be based on China's DF-31 series solid fuel ballistic missile. CZ-11 is reportedly 20.8 meters long (other reports suggest 18.7 meters) and 2 meters in diameter with a 120 tonne liftoff thrust. Its fourth stage has demonstrated in-space maneuvering capability. CZ-11 may be able to lift 350 kg or more to sun synchronous orbit. This was the first CZ-11 assembled at the CZ-11 Sea Launch home port at Haiyang, Shandong.

Dragon 2 Cargo

The 100th Falcon 9 to attempt orbit boosted the first unmanned Cargo Dragon 2 from Kennedy Space Center toward the International Space Station on December 6, 2020. Liftoff of SpaceX Cargo Resupply Mission 21 from Launch Complex 39 Pad A took place at 16:17 UTC. The Dragon 2 Cargo capsule carried 2.972 tonnes of cargo, including the 1.09 tonne Bishop Airlock mounted inside the aft truck section of the spacecraft.

The CRS-21 spacecraft was the first based on the Crew Dragon 2 design. It did not include the Super Draco abort thruster system or its abort propellant. The interior of the capsule had cargo mounting shelves in place of crew couches. Liftoff mass was not announced, but some reports suggest it was about 12.5 tonnes. It was the first time that NASA had used a crew-type spacecraft to carry cargo, something the USSR and Russia have done with Soyuz and Progress since the 1970s. The use of a common spacecraft promises engineering advantages and possible monetary savings over the long run.

First stage B1058.4 provided the first 2.5 minutes of boost before separating, flipping 180 degrees, and performing entry and landing burns to land of the Of Course I Still Love You drone ship positioned about --- km downrange in the Atlantic Ocean. The stage previously boosted the DM-2 Crew Dragon mission - the first with crew, ANASIS 2, and Starlink 1-12, all since May 30, 2020. The stage performed a prelaunch static firing at LC 39A on December 3 with CRS-21 attached. A December 5 launch attempt was scrubbed by weather conditions downrange.

It was the 99th Falcon 9 to reach orbit out of those 100 attempts, a total that includes a low-orbit partial failure that lost a secondary payload in 2012. A 101st Falcon 9 performed a suborbital crew abort test in early 2020. A 102nd Falcon 9 was destroyed with its AMOS 6 payload during pre-launch propellant loading for a static firing attempt at SLC 40 in 2016. The first five Falcon 9's were much different than the current variant. They were smaller, powered by Merlin 1C engines, and not designed for first stage recovery.

Gaofen 14

China's CZ-3B/E, flying for the first time as an enhanced "G5" variant with an extended payload fairing, boosted Gaofen 14, a "surveying and mapping satellite", from Xichang on January 6, 2020. Liftoff from LC 3 took place at 03:58 UTC. For the first time, CZ-3B/E flew south, south-west toward a sun synchronous Earth orbit. The 3.5 stage rocket usually flies on an east azimuth from Xichang toward geosynchronous transfer orbit.

Gaofen 14 may carry an optical remote sensing system built in Belarus. It will operate from 500 km altitude.

Gonets-M Launch

Russia's Soyuz 2.1b/Fregat M orbited three more Gonets M communication satellites and at least one classified satellite from Plesetsk Cosmodrome on December 3, 2020. Liftoff from Site 43 Pad 3 took place at 01:14 UTC. The Fregat M stage aimed to boost all four satellites into 1,400 km x 82.5 deg orbits during a roughly 2 hour mission that likely included two Fregat M burns.

It was the second Soyuz 2.1b/Fregat M to orbit Gonets M satellites, which weigh about 280 kg each at launch, or 840 kg total. The mass of the classified satellite was unknown, but previous Soyuz 2.1b/Fregat M vehicles have lofted more than 1.4 tonnes to similar orbits from Plesetsk in the past. Satellite numbers 30, 31, and 32 were launched on this mission. The satellites perform store and dump messaging. Now-retired Rokot performed earlier Gonets M launches.

Soyuz Kourou Launch

Russia's Soyuz 2.1a/Fregat performed the Arianespace VS24 mission from Kourou Space Center on December 2, 2020, carrying the FalconEye 2 optical Earth observation satellite for the Armed Forces of the United Arab Emirates (UAEAF) into sun synchronous orbit. Liftoff from the Soyuz launch complex (ELS) took place at 01:33 UTC. The 2.5 stage Soyuz completed its ascent 8 min 48 sec after liftoff. About one minute later, Fregat began the first of its three planned burns. The first placed the vehicle into an elliptical parking orbit. As first apogee approached, Fregat ignited for its second burn just under 55 minutes after liftoff. This burn circularized the orbit at about 611 km. The 1,190 kg Airbus Defense and Space/Thales Alenia Space satellite separated at T+58:45. Fregat performed an orbit lowering burn a bit less than an hour later.

The liftoff was delayed twice by weather and once by a data link issue during the three days before liftoff took place. Prior to that, the flight was delayed by months after an oxidizer leak was discovered involving a Fregat thruster. A decision was made to replace the stage, but the Covid-19 epidemic halted the entire campaign until late Fall. FalconEye 2 itself had originally been slated to fly on Vega, but was moved to Soyuz after the 2019 Vega failure. It was 2020's first Soyuz launch from Kourou.

H-2A Orbits Data Relay Satellite

Japan's H-2A boosted the classified Japan Data Relay Satellite (JDRS 1) into geosynchronous transfer orbit from Tanegashima on November 29, 2020. The H-2A-202 variant with two SRB-A strap on solid boosters began the F43 mission from Yoshinobu Pad 1 at 07:25 UTC. Webcast coverage of the mission ended shortly after liftoff. The second stage likely performed two burns during a roughly half-hour mission. About an hour after launch, MHI Launch Services confirmed that spacecraft separation had occurred.

JDRS 1 will raise itself to geostationary orbit, where it will relay data from both military and civil satellites that operate in low Earth orbit. It is equipped with a lasar communications system that can transmit data at up to 1.8 gigabits per seconds.

It was the third H-2A flight of the year. The final H-2B also flew from Tanegashima during 2020.

100th Falcon 9 Launch

The 100th SpaceX Falcon 9 launch boosted the 15th operational group of 60 Starlink internet satellites from Cape Canaveral, Florida on November 25, 2020. Liftoff from Space Launch Complex 40 took place at 02:13 UTC. For the first time in several Starlink missions, the Falcon 9 second stage performed a single ascent burn, this time reportedly aiming for a roughly 210 x 360 km x 53 deg deployment orbit. The Starlinks separated at about T+14 minutes 44seconds. They will ultimately move themselves to 550 km operational orbits. Total deployed payload mass was about 15,600 kg.

First stage B1049.7, on its fleet-leading seventh flight, fired for 2:32 before separating, flipping, and performing entry and landing burns to land on "Of Course I Still Love You" some 634 km downrange. The stage was static test fired on the pad on November 21, one day after an aborted attempt. B1049, the oldest currently active Falcon 9 first stage, previously boosted Telstar 18V, Iridium NEXT 8, and Starlinks v1-2, -7, and -10, with the first launch on September 10, 2018.

It was the 80th Falcon 9 v1.2 launched since 2015, and the 79th orbital flight. One additional v1.2 performed the suborbital Crew Abort test in early 2020 while an 81st Falcon 9 v1.2 was destroyed during propellant loading for the AMOS 6 pre-launch static firing test during 2016. Falcon 9 v1.1 flew 15 times during 2013-16, failing once. The original, much smaller, Merlin 1C Falcon 9 v1.0 variant launched five times during 2010-13, suffering one launch vehicle failure that lost a secondary payload but still managed to orbit its primary cargo Dragon payload.

CZ-5 Chang'e 5

China's CZ-5 launched Chang'e 5, intended to return a sample from the Moon, from Wenchang Spacecraft Launch Site on November 23, 2020. The 870 tonne, 2.5-stage rocket lifted off from Pad 101 at 20:30 UTC. CZ-5's liquid-hydrogen-fueled second stage fired its twin YF-75 engines twice to accelerate the 8.2 tonne spacecraft into a trans-lunar trajectory, from which it will steer itself toward lunar orbit.

The four kerosen/LOX boosters burned out about 177 secoonds after liftoff and separated two seconds later. The core stage fired its twin YF-77 LH2/LOX engines for a total of about 487 seconds. The second stage ignited three seconds later and fired for about 250 seconds to reach a parking orbit. The stage restarted about 1,677 seconds after liftoff for a roughly 233 second insertion burn. Chang'e 5 separated about 2,185 seconds after liftoff.

Chang’e spacecraft are named for a moon goddess in Chinese folklore. It is the first attempt to return lunar samples since 1976.

Sentinel 6 Launch

A brand new SpaceX Falcon 9 rocket orbited the ESA/NASA Sentinel-6 Michael Freilich satellite, the first of two identical satellites designed to precisely measure global sea-level trends, from Vandenberg AFB on November 21, 2020. Liftoff from VAFB SLC-4E took place at 17:17 UTC. The Falcon 9 second stage performed two burns to insert the 1,192 kilogram Airbus Defence and Space-built satellite into a 1,336 km x 66 deg orbit about 53 and a half minutes after liftoff. The non-sun-synchronous orbit will allow the satellite to revisit areas at different times of the day and night, providing an opportunity to measure sea levels at all hours of the day.

Sentinel 6 was named Michael Freilich for the former director of NASA’s Earth Science Division.

B1063.1 Lands at VAFB LZ4

First stage B1063.1 fired for a brief 2 min 17 sec before performing boost-back, entry, and landing burns to land at Landing Zone 4 adjacent to the launch site. The second stage burned for 5 min 50 sec to reach an initial elliptical transfer orbit. After a coast to apogee, the stage restarted for about 10 seconds at T+ 53 min 18 sec to circularize the orbit. Sentinel 6 separated moments later.

The Falcon 9 stages were acceptance tested at McGregor, Texas, likely during July, 2020. The assembled rocket was briefly static test fired at VAFB SLC 4E on November 17. The second stage was expected to deorbit over the South Pacific during the second orbit.

It was the first West Coast Falcon 9 launch since June 12, 2019.

Electron 16

Rocket Lab’s Electron launched for the 16th time on November 20, 2020, with 29 tiny Cubesats and a mass simulator in the shape of a small gnome statue. Liftoff from New Zealand's Mahia Peninsula LC 1 took place at 02:20 UTC. The three-stage Electron/Curie rocket, named "Return to Sender”, boosted a total active payload of only about 45-50 kg into a 500 km x 97.3 deg sun synchronous orbit during the roughly one-hour mission.

In a first test of its type for Electron, the first stage, after separating, fired thrusters to orient itself for reentry, then deployed drouge and main parachutes and splashed down in the Pacific Ocean less than 13 minutes after liftoff. A ship recovered the floating stage. The stage will be inspected as part of an effort to develop a reusable first stage that in the future would be recovered in mid-air by a helicopter.

The first stage fired for about 2 minutes 33 seconds and the second for about 6 minutes 7 seconds to insert the storable propellant Curie upper stage and payload into an ellipical transfer orbit. Curie coasted to a 500 km apogee where, beginning at T+49:38, it fired for about 90 seconds to circularize the orbit. The satellites separated around one hour after liftoff.

Vega VV17 Fails

Europe's Vega suffered its second failure in its past three launches while attempting to orbit two Earth observation satellites on November 17, 2020. The AVUM liquid upper stage appeared responsible.

The VV17 mission for Arianespace lifted off from the Kourou's ZLV pad at 01:52:20 UTC. Spain's SEOSAT-Ingenio and France's TARANIS topped the rocket inside its fairing. The plan was for Vega to place SEOSAT-Ingenio into a 670 km x 98.09 deg sun-synchronous orbit and TARANIS into a 700 km x 98.19 deg sun-synchronous orbit during a 1 hour 42 minute mission that would have included four AVUM burns.

Vega’s three solid propellant motors fired successfully, but AVUM suffered a problem during its first burn, which was intended to place the stage and payload into an initial elliptical parking orbit. The problem caused loss of mission, with AVUM and its payload apparently falling short of orbit.

Within hours, Arianespace reported that the upper stage had tumbled out of control shortly after ignition because control cables had been improperly installed. Telemetry indicated that cables to two thrust vector control actuators had been inverted. Commands meant for one had been routed to the other, and vice versa.

Crew Dragon Launch

Falcon 9 launched the Crew 1 mission to the International Space Station from Kennedy Space Center on November 16, 2020. On board Crew Dragon C207 "Resilience" were NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker along with Japan Aerospace Exploration Agency astronaut Soichi Noguchi. All but Glover were space veterans. It was the first operational commercial crew flight.

Liftoff from LC 39 Pad A took place at 00:27 UTC. Crew Dragon separated from the Falcon 9 second stage about 12 minutes after liftoff to begin its one day trip to dock with ISS.

First stage B1061.1 fired its nine Merlin 1D engines for 2 min 37 sec, aiming the vehicle on a northeast trajectory off the eastern U.S. coast, before shutting down and separating. The stage performed entry and landing burns before landing on the "Just Read the Instructions" drone ship about 9 min 29 sec after liftoff. The second stage fired its single Merlin 1D Vacuum engine from T+2 min 48 sec until T+8 min 50 sec to reach a roughly 190 x 210 km x 51.6 deg low earth orbit.

The first stage was static fired at McGregor, Texas, on April 24, 2020. Two of its Merlin 1D engines were replaced after close inspection in the wake of the GPS 3-4 booster abort problem. B1061.1 performed a brief static test firing at LC 39A on November 11, 2020 with Crew Dragon stacked atop the vehicle.

Atlas 5/NROL-101

United Launch Alliance Atlas 5-531, boosted by the first three Northrop Grumman GEM-63 solid rocket motors, orbited NROL-101 for the U.S. National Reconnaisance Office from Cape Canaveral, Florida on November 13, 2020. Liftoff from SLC 41 took place at 22:32 UTC. The AV-090 vehicle, topped by a Medium height, 5 meter diameter fairing stood 62.8 meters tall.

AV-090 flew sharply northeast, skirting the Eastern Seaboard and apparently overflying Newfoundland. It appeared bound for a relatively high inclination orbit, possibly a Molniya type, 12-hour orbit, though that is speculation. The classified mission could be a data relay satellite, or it could be something else. Mission success was not announced until about 2.5 hours after liftoff, indicating a possible long coast to Centaur restart and/or payload separation.

AV-090 performed a wet dress rehearsal at SLC 41 on October 21. The payload was stacked five days later. A November 5 launch attempt was scrubbed by LOX ground system problems.

GEM 63 is 63 inches diameter and 66 feet (20.12 m) long. The booster, which replaces the original Aerojet AJ-62, burns 44.23 tonnes of propellant for 94 seconds, producing up to 168.54 tonnes of thrust. A stretched, more-powerful GEM 63XL version is slated to boost ULA's upcoming Vulcan Centaur

CZ-3B Orbits Comsat

China's Chang Zheng (Long March) 3B/E orbited the second Tiantong 1 mobile communications satellite (Tiantong 1-02) from Xichang Satellite Launch Center on November 12, 2020. Liftoff from Launch Complex 2 took place at 15:59 UTC. The satellite, which may have weighed 5 tonnes or more, was inserted into a geosynchronous transfer orbit after two burns by the rocket's liquid hydrogen fueled upper stage.

After it raises itself to geostationary orbit, the satellite will provide mobile communications coverage to China, the Middle East, Africa, and the Indian and Pacific Oceans. Tiantong 1-02 provides S-band mobile communications services for China SatCom. It was developed by the Chinese Academy of Space Technology. The first Tiantong 1 was launched on August 5, 2016.

India Launch

After enduring a long year fighting Covid-19, India returned to space for the first time during 2020 with a PSLV launch of the EOS-1 radar Earth observation satellite from Satish Dhawan Space Center at Sriharikota on November 7, 2020. Liftoff from the First Launch Pad took place at 09:37 UTC during a rainstorm. It was the second flight of a PSLV-DL variant, which uses two PS0M-XL strap-on solid motors.

The 4.5 stage rocket, performing mission number C49, fired its strap-on motors for 1 minute 10 seconds, its S139 first stage solid motor for 1 minute 50 seconds, and its Vikas-powered UDMH/N2O4 fueled second stage for 2 minutes 13 seconds to boost its MMH/MON fueled fourth stage on a coast toward apogee where its twin L-2-5 engines ignited to provide the orbital insertion. The 628 kg EOS-1 satellite separated into a 575 km x 36.9 deg orbit. Nine nanosatellites were also orbited.

Ceres-1 Inaugural

China's Ceres-1 launch vehicle performed its first launch successfully from Jiuquan Satellite Launch Center on November 7, 2020, placing a small, 50 kg data transfer satellite named Tianqi 11 into a 500 km x 97.4 deg sun synchronous orbit.

Ceres-1, a 31 tonne, 19 meter tall rocket uses three HTBD solid motors topped by a liquid propellant fourth stage. It is able to lift 230 kg to 700 km sun synchronous orbits, or 350 kg to a 200 km lower inclination orbit. A commercial company, Galactic Energy, developed and launched the rocket. It is likely based in part on existing China missile technology. Its first two stages, for example, share the same 1.4 meter diameter dimension as China's DF-21/25/26 IRBM family.

The first stage GS-1 motor produces 60 tonnes thrust during a 74 second burn. The GS-2 second stage makes 28 tonnes thrust for 70 seconds. The GS-3 third stage produces 8.8 tonnes thrust for 69 seconds. The liquid fourth stage uses low-thrust, pressure-fed engines for insertion burns and can fire for up to 310 seconds. Ceres-1 launched from a simple steel launch stand standing on a flat pad.

Galactic Energy is the fourth commercial Chinese company to make an orbital attempt since the first in 2018. Landspace failed in October 2018, followed by OneSpace in March 2019. The iSpace company became to the first to succeed with its Hyperbola 1 launcher during July 2019.

CZ-6 Launch

China's fourth Chang Zheng 6 (CZ-6) orbited 13 microsatellites from Taiyuan Satellite Launch Center on November 6, 2020. Liftoff from LC 16 took place at 03:19 UTC. On board were ten 37.5 kg Satellitelogic NuSats for Argentina and three small satellites for China. The three-stage rocket lifted a total payload of at least 500 kg into a 500 km x 97.5 deg sun synchronous orbit.

CZ-6, the first of China's all-new launch vehicle generation, debuted from the same site on September 19, 2015 and flew again on November 21, 2017 and November 13, 2019. A single 122 tonne thrust, staged-combustion cycle YF-100 LOX/kerosene engine powered the routhly 103 tonne, three-stage launch vehicle off of its launch pad. YF-100, China's first big LOX/kerosene engine, also powers the country's larger CZ-5 and CZ-7 launch vehicles. The first stage burned for about 155 seconds. The second stage, powered by a YF-115 staged combustion engine producing 18 tonnes of thrust, burned LOX/kerosene for about 290 seconds. At apogee, a small kick stage, powered by four 408 kgf thrust YF-85 hydrogen peroxide/kerosene engines, fired to circularize the orbit.

CZ-6 is capable of lifting 1,080 kg into a 700 km sun synchronous orbit. It is integrated horizontally in a hangar. A large wheeled transporter/erector carries it to its flat launch pad and erects it shortly before launch.

GPS 3-4

The 100th SpaceX Falcon 9-family launch boosted GPS 3-4 into a 419 x 22,440 km x 55 degree transfer orbit for the U.S. Space Force from Cape Canaveral, Florida on November 5, 2020. Liftoff from Space Launch Complex 40 took place at 23:24 UTC. The liftoff ended a long-delayed campaign that included a static test on September 25 and a last-second aborted launch attempt on October 3. That auto-abort at T-2 seconds resulted from prematurely high pressure buildup in two Merlin 1D first stage engine gas generators.

The October 3 abort forced a fast-paced investigation that found a previously unknown Merlin 1D flaw. The two engines were removed and sent to McGregor, Texas for testing, where the problem was reproduced. Testing discovered that a production process masking lacquer material had blocked a vent hole leading to a relief valve in the engine's gas generators. Two new Merlin 1D engines took their place on the brand-new B1062.1 booster. The flaw was found to affect other boosters built after B1060.

The GPS 3-4 satellite was sent back to Astrotech in Titusville, Florida for battery charging while another Falcon 9 launched from SLC 40. The campaign restarted with a new static test at SLC 40 on October 31 and with return of the satellite to the launch complex on November 1.

Falcon 9 climbed on a northeast track up the Eastern seaboard. Its B1062.1 first stage fired for 2 min 31 sec before flipping 180 degrees to perform entry and landing burns to land on the “Of Course I Still Love You” droneship floating in the Atlantic Ocean. The second stage fired for 5 min 25 sec to reach a parking orbit. It restarted about 63 min 32 sec after liftoff, firing for 45 seconds to reach its insertion orbit. GPS 3-4 separated about 25 minutes later while the 4,311 kg spacecraft was in view of ground stations in Hawaii and California.

It was the 96th Falcon 9 orbital attempt. One additional Falcon 9 performed a suborbital crew abort test. Three Falcon Heavy launches increase the total to 100.

Electron 15

Rocket Lab’s Electron performed its 15th launch on October 28, 2020, with a 21:21 UTC liftoff from New Zealand's Mahia Peninsula LC 1. The three-stage Electron/Curie rocket, named "In Focus”, orbited Canon Electronics 35.5 kg CE-SAT-IIB and nine Planet Flock 4e SuperDove cubesats that together weighed about 45 kg.

The first stage fired for about 2 minutes 42 seconds and the second for about 6 minutes 12 seconds to insert the storable propellant Curie upper stage and payload into an ellipical transfer oribt. Curie coasted to a 500 km apogee where, beginning at T+51:06, it fired for 2 minutes 6 seconds to circularize the 97.5 deg sun synchronous orbit. The satellites separated around one hour after liftoff.

The liftoff followed an October 21 launch attempt that was scrubbed by bad oxygen sensor data.

CZ-2C/Yaogan 30-07

China orbited its seventh set of Yaogan 30 triplet satellites on October 26, 2020 with a Chang Zheng 2C launch vehicle. The two stage rocket rose from Xichang Satellite Launch Center's LC 3 at 15:19 UTC. The satellite triplet was named Yaogan-30 Group 7. The "electromagnetic detection" satellites were inserted into roughly 600 km x 35 deg orbits.

The satellites may be formation flyers similar to the U.S. NOSS system, which perform a signals intelligence mission designed to monitor surface ship electronic emissions. It was the seventh launch for this constellation, all by CZ-2C rockets from Xichang LC 3, since September 29, 2017.

Glonass-K Launch

Russia's Soyuz 2-1b/Fregat orbited a Glonass-K navigation satellite from Plesetsk Cosmodrome on October 25, 2020. Liftoff from Site 43 Pad 3 took place at 19:08 UTC. Fregat performed three burns to deliver the satellite (Uragan-K 15L) into a roughly 19,100 km x 64.8 degree circular medium earth orbit about 3.5 hours after liftoff.

The satellite weighed about 935 kg at launch.

Starlink v1-14

Falcon 9 first stage B1060.3 powered the Starlink v1-14 mission toward orbit from Cape Canaveral SLC 40 on October 24, 2020 with 60 more Starlink satellites. Liftoff took place at 15:31 UTC. The 60-satellite, 15.6 tonne payload separated into a roughly 260 km x 53 deg low Earth orbit about 63 minutes after liftoff.

The first stage, which previously boosted the GPS 3-3 and Starlink v1-11 flights, fired for 2 minutes 32 seconds, then separated and performed entry and landing burns before landing on the “Just Read the Instructions” droneship 634 km downrange in the Atlantic Ocean. The stage had been briefly static fired with second stage and payload at SLC 40 on October 21. An inital launch attempt was scrubbed about 15 minutes before T-0 on October 22 when a second stage engineering camera lost power.

The second stage fired its Merlin Vacuum engine for about 6 minutes 10 seconds to reach a parking orbit, then restarted at T+44:36 for two seconds to raise perigee. The stage was expected to perform a reentry burn targeting a reentry south of Australia during the second orbit.

It was the 75th successful orbital Falcon 9 v1.2, a record achieved in less than five years of service. It was also the 13th SpaceX-owned Starlink launch of 2020, out of 18 total orbital Falcon 9 flights.

Starlink v1-13

Falcon 9 first stage B1051.6 boosted the Starlink v1-13 mission toward orbit from Kennedy Space Center LC 39A on October 18, 2020 with 60 more Starlink satellites. Liftoff took place at 12:25 UTC. The 60-satellite, 15.6 tonne payload separated into a roughly 260 x 280 km x 53 deg low Earth orbit about 63 minutes after liftoff.

The first stage, which previously boosted the DM-1 unmanned Crew Dragon flight, Canada's RCM mission, and Starlink v1 Flights 3, 6, and 9, fired for 2 minutes 32 seconds, then separated and performed entry and landing burns before landing on the “Of Course I Still Love You” droneship 633 km downrange on the Atlantic Ocean. The stage had been hot fired at LC 39A on October 17. Both fairing halves were flying for the third time. They were caught by SpaceX recovery ships, though one broke through Ms Tree's catch net and may have been damaged.

The second stage fired its Merlin Vacuum engine for 6 minutes 5 seconds to reach a parking orbit, then restarted at T+44:04 for two seconds to raise perigee. The stage was expected to perform a reentry burn targeting a reentry south of Australia during the second orbit

Soyuz MS-17 Launch

A Russian Soyuz 2.1a boosted Soyuz MS-17 into orbit from Baikonur Cosmodrome with three crew on October 14, 2020. Russia's Sergey Ryzhikov and Sergey Kud-Sverchkov and NASA's Kate Rubins lifted off from Site 31 Pad 6 at 05:45 UTC, beginning an ultra-fast three-hour ascent to dock with the International Space Station at 08:48 UTC. It was the first use of the three-hour ascent during a crewed mission.

The flight carried the final planned NASA-purchased seat for a U.S. astronaut. The Agency plans to switch to SpaceX Crew Dragon and Boeing Starliner spacecraft for future flights. It is possible that the U.S. and Russia will in the future perform seat-swaps, with Russians occasionally riding the U.S. vehicles and U.S. crewmembers riding Soyuz.

CZ-3B/Gaofen 13

China's Chang Zheng 3B launched Gaofen 13, a big optical reconnaisance satellite, into geosynchronous transfer orbit from Xichang Satellite Launch Center on October 11, 2020. Liftoff of the "Enhanced" CZ-3B, tail number number Y63, from LC 2 took place at 16:57 UTC. The liquid hydrogen third stage performed two burns during the roughly half-hour mission.

The satellite appears to be an improvement from Gaofen 4, which was launched to GTO by another CZ-3B in 2015. It consists of a large central telescope section extending from a base section that itself sports twin solar arrays. In geosynchronous orbit, such a satellite could be aimed to image any area at any time on probably more than one-third of the Earth's surface whenever cloud cover permits. CZ-3B/E can boost more than 5.5 tonnes to GTO. This satellite likely approached the upper capability of the launch vehicle.

Once again, China provided only last-minute notice of the launch.  It was the 21st DF-5 based orbital launch of the year and 20th success. It was also China's 30th orbital attempt of the year and 26th success.

Starlink v1-12 Launch

Nineteen days after its first attempt, after suffering a late-count abort on October 1 and weather scrubs on September 17, 28, and October 5, a Falcon 9 powered by first stage B1058.3 finally launched from Kennedy Space Center LC 39A on October 6, 2020 with 60 more Starlink satellites. The Starlink v1.0-12 mission (SpaceX confusingly also identified it as "Starlink 13") lifted off at 11:29 UTC. The 15.6 tonne payload separated into a roughly 260 x 280 km x 53 deg low Earth orbit about 61.5 minutes after liftoff.

The first stage, which previously boosted the historic Commercial Crew DM-2 mission and the ANASIS 2 launch, fired for 2 minutes 32 seconds, then separated and performed entry and landing burns before landing on the “Of Course I Still Love You” droneship in the Atlantic Ocean. One of the fairing halves was caught by a SpaceX recovery ship - a rare success for that recovery method. One of the halves had previously flown twice, on the Starlink v0.9 and v1.0-15 launches.

The second stage fired its Merlin Vacuum engine for 6 minutes 5 seconds to reach a parking orbit, then restarted at T+42:26 for two seconds to raise perigee. Although the stage was expected to perform a reentry burn of some type after payload separation, it remained in a 238 x 261 km x 52.99 deg orbit as of October 17.

Antares/Cygnus NG-14

The 13th Antares launch vehicle - and third upgraded Antares 230+ - boosted Northrop Grumman's Cygnus NG-14 cargo spacecraft into orbit from Wallops Island, Virginia on October 3, 2020. Liftoff from Pad 0A took place at 01:16 UTC. The liftoff followed an aborted attempt one day earlier at T-2:40 caused by a ground problem.

Like Antares 230, the Antares 230+ first stage is powered by two Energomash RD-181 engines in place of the AJ-26 engines that powered the first five Antares flights. Antares 230+ uses a stronger first stage structure to allow full-thrust operation through much of its burn. In addition, unneeded dry mass was stripped from the first and second stages and a single-piece interstage was implemented.

Cygnus NG-14 was the 11th enhanced Cygnus with a stretched Thales Alenia Space cargo module and the eighth to fly on Antares. Atlas 5 rockets orbited the other three. NG-14 probably weighed about 7,420 kg at launch, including 3,551 kg of cargo for the International Space Station. Cygnus NG-14 was named in honor of Kalpana Chawla, NASA's first female astronaut of Indian descent, who died during the failed STS-107 reentry of Space Shuttle Columbia.

The RD-181 engines produced 392 tonnes of thrust to power the nearly 293 tonne rocket off its pad. The Ukrainian-built first stage burned for about 198 seconds. After first stage shutdown, the upper composite separated at T+206 seconds and coasted upward. The shroud and interstage adapter separated at 235 and 240 seconds, respectively. At about T+258 seconds the Northrop Grumman Castor 30XL second stage motor ignited to produce an average of about 51 tonnes of thrust during its roughly 165 second burn. Cygnus separated at T+537 seconds into a 183 x 262 km x 51.649 deg orbit.

Gonets-M Launch

Russia's Soyuz 2.1b/Fregat M orbited three Gonets M communication satellites and 18 small rideshare payloads from Plesetsk Cosmodrome on September 28, 2020. Liftoff from Site 43 Pad 4 took place at 11:20 UTC. The Fregat M stage placed its primary payloads into 1,400 km x 82.5 deg orbits.

It was the first use of Soyuz 2.1b/Fregat M to orbit Gonets M satellites. Now-retired Rokot performed previous launches. Satellite numbers 27, 28, and 29 were launched on this mission. The satellites perform store and dump messaging.

Rideshare satellites from Finland, the USA, Canada, Lithuania, Germany, the UAE, and Russia were also orbited on this flight.

CZ-4B Taiyuan Launch

China's Chang Zheng 4B (CZ-4B number Y42) boosted the HJ-2A and HJ-2B environmental monitoring satellites into orbit from Taiyuan Satellite Launch Center on September 27, 2020. Liftoff from Pad 9 took place at 03:23 UTC. The satellites replace HJ-1A and HJ-1B. They will provide multispectral imaging to monitor the environment, natural resources, water conservancy, and agriculture and forestry.

CZ-4B/HY 2C

China's Chang Zheng 4B (CZ-4B) number Y41 carried Haiyang 2C (HY 2C), an ocean observation satellite, into low earth orbit from Jiuquan Satellite Launch Center on September 21, 2020. Liftoff from LC 43 Pad 94 (43/603) took place at 05:40 UTC. The three-stage hypergolic propellant rocket inserted its payload into a 931 x 948 km x 66 deg orbit with third stage cutoff 12 minutes 27 seconds after liftoff. The stage performed a single 7 minute 35 second burn during the ascent. After spacecraft separation, the third stage performed a depletion burn to lower its apogee to 654 km, enabling its eventual reentry.

HY 2C carried a microwave radiometer to monitor sea states.

The first stage was fitted with four grid fins, similar to Falcon 9 first stages, for steering the stage toward a smaller drop zone box.

CZ-11 Sea Launch

China's CZ-11 performed its second orbital launch from a floating platform on the Yellow Sea on September 15, 2020. The four-stage, DF-31 missile-based rocket, tail number HY2, boosted nine imaging satellites into 535 km sun synchronous orbits after an 01:23 UTC launch from the new Debo 3 ship. The ship replaces a barge used for the first sea launch in 2019.

Three Gaofen 03C video satellites and six Gaofen 03B push-broom (scanning) satellites were orbited. The rocket flew on a southbound ascent profile for the first time from this site. The first stage drop zone was offshore from China's east coast while the second stage flew directly over the length of Taiwan from north to south.

KZ-1A Failure

China's Kuaizhou 1A launch vehicle failed to place its Jilin-1 Gaofen 02C remote sensing satellite into low earth orbit as planned after a 05:02 UTC liftoff from Jiuquan Satellite Launch Center on September 12, 2020. It was the first failure of the Kuaizhou 1/1A series after 11 previous successes since 2013. This rocket, tail number Y3, was the 10th improved KZ-1A variant to fly.

Gaofen 02C was to have been inserted into a 535 km sun synchronous orbit. It weighed about 230 kg at launch. Some reports suggested that the hypergolic liquid upper stage failed, preventing completion of the final apogee kick insertion burn.

Expace Technology Co., Ltd., a subsidiary of China Aerospace Science & Industry Corp., managed the launch campaign.

Rocket 3.1 Fails

Astra's Rocket 3.1, a small two-stage LOX/Kerosene fueled rocket, failed during its first orbital launch attempt from Alaska's Kodiak Launch Pad 3B on September 12, 2020, after a 03:20 UTC liftoff. The rocket rose for slightly more than 20 seconds before, acccording to Astra, oscillations introduced by the guidance system caused "the vehicle to drift from its planned trajectory, leading to a commanded shutdown of the engines by the flight safety system". Witnesses saw the vehicle tumbling out of the sky to an explosive impact on the ground after its five battery-powered Delphin rocket engines cut off.

The company's earlier, March 2020 attempts to fly Rocket 3.0 for the Darpa Challenge failed to produce a launch after multiple countdowns. A final, March 23 attempt ended with a prelaunch failure that destroyed the rocket and started a fire at the launch site.

Astra Rocket stands 11.6 meters tall and is 1.32 meters diameter. Its probably weighs 10-11 tonnes at liftoff, rising on 14.275 tonnes of thrust. It uses an "ultra-low-cost" metal structure. Although designed to place at least 100 kg into a presumably near-polar low Earth orbit, Astra 3.1 carried no payload during this initial orbital flight test.

Astra performed two suborbital test launches during 2018 from Kodiak, Alaska, using only live first stages. The first, an Astra Rocket 1.0 flown from Launch Pad 2 on July  21, 2018, reportedly failed about 60 seconds after liftoff. The second, an Astra Rocket 2.0, failed shortly after its November 29, 2018 attempt from the same pad.

CZ-4B Launch

China's Chang Zheng (CZ) 4B, tail number Y46, orbited another remote sensing satellite, named Gaofen 11-02, on September 07, 2020. Liftoff of the storable propellant rocket from Taiyuan Satellite Launch Center's LC 9 took place at 05:57 UTC. The three-stage storable propellant rocket boosted its payload into a 248 x 694 km x 97.3 deg sun synchronous type low Earth orbit. The satellite will likely adjust itself toward a roughly 500 km near-circular orbit over time if the history of Gaofen 11-01 is a guide.

According to reports from China, the satellite carried high resoultion optical imaging equipment and will be used for civil planning, disaster prevention and mitigation, and national defense, among other uses. While the mass of the satellite was not announced, CZ-4B is able to lift 2.5 tonnes to a 700 km sun synchronous orbit.

It was the year's third CZ-4B launch and the 18th DF-5 based orbital attempt.


Secret CZ-2F Launch

China's CZ-2F, flying for the first time in nearly four years, boosted a top secret experimental reusable test spacecraft into orbit from Jiuquan Satellite Launch Center on September 4, 2020. Liftoff from Site 43/91 took place at about 07:30 UTC. Four objects were subsequently tracked, two in roughly 330 x 348 km x 50.2 deg orbits and two in roughly 346 x 566 km x 49.9 deg orbits. Xinhua announced that the test spacecraft would orbit for an unspecified period of time before returning to Earth at a "domestic landing site". No details about the spacecraft and no photographs of the launch or of the launch vehicle were initially released. It was not clear if the spacecraft was winged or was a ballistic reentry vehicle, for example.

On September 6, Xinhua news agency reported that the reusable spacecraft had landed. No details about the landing site or landing time and no photographs were provided. The type of spacecraft was also not mentioned. Meanwhile, some apparently unofficial videos of the launch were made available. These showed a rocket with a standard width fairing similar to that used by the type "T" CZ-2F.

Falcon 9/Starlink 1 F11

A Falcon 9 performing the 100th SpaceX orbital launch attempt orbited the eleventh operational group of 60 Starlink internet satellites from Kennedy Space Center on September 3, 2020. Liftoff from Launch Complex 39 Pad A took place at 12:46 UTC. The Falcon 9 second stage performed a single ascent burn to reach a roughly 220 x 380 km x 53 deg deployment orbit. The Starlinks separated at about T+14 minutes 47 seconds. They will ultimately move themselves to 550 km operational orbits.

Total deployed payload mass was about 15,600 kg. The flight increased the total number of orbited Starlink satellites, both precursor and operational, to 715, though several have been retired and are being deorbited. A constellation of thousands of the 260 kg, Redmond Washington-built satellites is planned.

First stage B1060.2, on its second flight; which previously boosted GPS 3-3 from SLC 40 on June 30, 2020; performed entry and landing burns before landing on "Of Course I Still Love You" some 350 nautical miles downrange. The stage was not hot-fired on the pad prior to launch, a practice now becoming common. The stage is the newest currently-active Falcon 9 booster, though three or four more have been built and tested and are preparing for flight.

Attempts to recover the new payload fairing halves failed.  Recovery boats returned to Port Canaveral with only shroud fragments. The second stage was to have performed a deorbit burn during its first orbit in order to target an impact zone off the California coast. No confirmation of that burn and reentry was possible as of several days after the launch.

Vega Returns

After months of delay caused by Covid-19, high altitude winds, and a typhon on the other side of the planet, Europe's Vega rocket finally returned to service with launch of the VV16 Small Spacecraft Mission Service (SSMS) Proof of Concept (PoC) mission from Kourou Space Center on September 3, 2020. Liftoff from Kourou's Vega Launch Zone (ZLV) took place at 01:51 UTC. Vega's AVUM upper stage performed four burns to insert 53 micro and nanosatellites into 515 km and 530 km sun synchronous orbits. The final satellite separated about 1 hour 45 minutes after liftoff.

It was Vega's first launch since July 2019, when VV15's Zefiro 23 second stage motor suffered a forward dome burn-through as it fired.

The European Space Agency (ESA) funded SSMS development, which includes a modular SSMS dispenser. VV16 carried seven microsatellites (15 to 150 kg) on an upper dispensar part and 46 smaller CubeSats on a lower dispensar "Hexamodule". Total satellite mass was 877 kg.

Electron 14

Rocket Lab’s Electron returned to service with its 14th launch on August 31, 2020. The three-stage Electron/Curie rocket, named "I Can’t Believe It’s Not Optical”, boosted Capella Space's "Sequoia" synthetic aperature radar (SAR) mapping satellite. Liftoff from New Zealand's Mahia Peninsula LC 1 took place at 03:05 UTC. After a 2 minute 36 second first stage burn and a 6 minute 9 second second stage firing, the storable propellant Curie upper stage and payload coasted to a 530-ish km apogee where, beginning at T+52:52, Curie fired for 2 minutes 26 seconds to circularize the 45 degree inclination orbit. The 100 kg satellite separated about one hour after liftoff into a 531 x 546 km x 45.1 deg orbit.

After Sequoia separated, the Curie stage transitioned into Photon test spacecraft mode, flying in a 528 x 547 x 45.1 deg orbit for an extended test. Photon carries solar cells and rechargeable batteries and uses the Curie stage's RCS and control systems to maintain flight control. The roughly 50 kg Curie/Photon can carry up to 170 kg of payload while serving as a satellite bus in a manner reminiscent of Lockheed's long-retired Agena stage.

The launch took place nearly two months after Electron 13 failed to reach orbit when its second stage engine shut down early. Rocket Lab’s investigation determined that an overheating electrical connection that carried engine turbopump current was to blame for the failure. Improved testing methods were developed to detect such potential failures in the future.

It was the year's 60th successful orbital launch.

Falcon 9 Orbits SAOCOM 1B

A Falcon 9 v1.2 placed Argentina's SAOCOM 1B into sun synchronous low Earth orbit from Cape Canaveral, Florida on August 30, 2020. Liftoff from SLC 40 took place at 23:19 UTC. It was the first near-polar orbit launch from the Cape since Delta 67 orbited ESSA 9 during 1969. After firing for 2 minutes 17 seconds during ascent, first stage B1059.4, on its fourth launch, performed boost-back, entry, and landing burns to land at Cape Canaveral's Landing Zone 1. It was the 15th successful landing at LZ 1 out of 16 attempts since 2015. Three additional landings have taken place at nearby LZ 2 during Falcon Heavy flights.

The second stage performed one, 461 second burn to carry the 3,050 kg satellite into a roughly 610 km orbit. During the burn, the stage doglegged from south-southeast to south-southwest along the eastern Florida coast. The stage then flew over Cuba and Panama before deploying SAOCOM 1B about 14 minutes 9 seconds after liftoff. Two microsatellites, GNOMES-1 and Tyvak-0172, separated at about T+61 and 62 minutes.

The first stage prevously launched CRS-19, CRS-20, and Starlink V1 F8 during 2019-2020. It was not static test fired prior to this launch. The SAOCOM 1B launch was originally scheduled for early 2020, but the Covid-19 pandemic prevented ground crew travel from Argentina, causing delays. A Falcon 9 orbited similar SAOCOM 1A from VAFB SLC 4E during 2018. The relatively light payload allowed SpaceX to shift the SAOCOM 1B launch to the Cape in a move meant to save money. The company shifted or shed most of its VAFB launch team after completing its Iridium NEXT constellation launches in 2018.

CZ-2D/Gaofen 9-05

China's CZ-2D orbited Gaofen 9-05, adding to the growing Gaofen 9 Earth observation satellite constellation, from Jiuquan Satellite Launcher Center on August 23, 2020. Liftoff of CZ-2D Y57 from LC 43/94 (43/603) took place at 02:27 UTC. A pair of microsatellites, one named Tiantuo 5 and one identified as a "multi-functional test satellite" were orbited. Gaofen 9-05 separated into a sun synchronous orbit.

It was the fourth CZ-2D/Gaofen 9 launch in 2020 to date, all from Jiuquan.

Falcon 9/Starlink 1 F10

Falcon 9 first stage B1049.6 on its sixth flight - a new record for Falcon 9 - boosted the tenth operational group of 58 Starlink internet satellites from Cape Canaveral on August 18, 2020, along with three rideshare Planet Skysat imaging satellites. Liftoff from Space Launch Complex 40 took place at 14:31 UTC. The Falcon 9 second stage performed a single ascent burn to reach a roughly 220 x 380 km x 53 deg deployment orbit. Skysats 19-21 separated between 12 and 14 minutes after liftoff. The Starlinks separated at about T+46 minutes. The Starlink satellites will ultimately move themselves to 550 km operational orbits.

Total deployed payload mass was about 15,440 kg, including about 120 kg for each of the Skysats. The flight increased the total number of orbited Starlink satellites, both precursor and operational, to 655, though several are being retired and deorbited. A constellation of thousands of the 260 kg, Redmond Washington-built satellites is planned.

The payload fairing halves previously flew and were recovered during the January, 2020 Starlink 1 F3 launch. The first stage, which previously boosted Telstar 18 VANTAGE in September 2018, Iridium-8 in January 2019, and three Starlink missions in May 2019, January 2020, and June 2020, performed entry and landing burns before landing on "Of Course I Still Love You" some 350 nautical miles downrange. The stage was hot-fired at SLC 40 on August 17 with payload attached. It is the oldest currently-active Falcon 9 booster.

It was the 70th orbital Falcon 9 v1.2 and the 13th orbital Falcon 9 flight of 2020. SpaceX-owned Starlink has accounted for 9 of the launches. The company has only performed two beyond-LEO launches during 2020 to date.

Ariane 5 Launch

Ariane 5 ECA L5112 performed the Arianespace Mission VA253 launch from Kourou on August 15, 2020. Liftoff from ELA 3 took place at 22:04 UTC. The 47 minute 39 second mission successfully deployed three satellites into geosynchronous transfer orbit.

Northrop Grumman-built Galaxy 30 and MEV-2, which were connected together at launch, rode atop the Sylda adapter. 3,298 kg Galaxy 30, a GEOStar-2.4E communications satellite for Intelsat to serve the USA, separated at T+27 min 47 sec. 2,976 kg MEV-2, the second Mission Extension Vehicle 2 (MEV-2) spacecraft, a GEOStar-3 designed to dock with old satellites to extend their lifetimes, separated at T+34 min 22 sec. MEV-2 will dock with Intelsat 10-02 in geosynchronous orbit.

BSAT-4b, a 3,530 kg Maxar (Space Systems/Loral) SSL-1300 series communications satellite, rode inside Sylda and separated at T+47 min 37 sec. It will serve Japan's Broadcasting Satellite System Corporation (BSAT) , which provides communication and broadcasting satellite services for Japan.

The launch followed an aborted July 31 launch attempt that forced a rollback to replace a defective sensor. It was the first Ariane 5 launch since February, operations having been affected by the Covid-19 pandamic.

ULA/SpaceX Win NSSL

On August 7, 2020, the U.S. Space Force awarded National Security Space Launch Phase 2 contracts to United Launch Alliance and SpaceX, locking out bidders Blue Origin (New Glenn) and Northrop Grumman (Omega) as primary contractors, though both would serve as subcontractors for ULA's winning Vulcan launch vehicle.

ULA won about 60% of the launch services orders and SpaceX about 40% during 2020-2024. ULA will launch USSF-51 and USSF-106 during 2022. SpaceX will launch USSF-67 during 2022. ULA won $337 million and SpaceX $316 million for these initial launch services task orders. Some of the SpaceX money may be for development of an extended Falcon Heavy payload fairing and for a new Mobile Service Tower at LC 39 Pad A.

ULA and SpaceX will now compete annually for up to 34 NSSL launches during during the 2020-2027 period. The initial launches will be from Florida, with California launch capability added after a couple of years. Vulcan Centaur will launch from Cape Canaveral SLC 41 and VAFB SLC 3E. Falcon 9/Heavy will launch from KSC LC 39A and VAFB SLC 4W, with some launches likely possible from Cape Canaveral SLC 40.

Blue Origin announced that it intended to continue development of its New Glenn launch vehicle, aiming to win civil and commercial space contracts. Northrop Grumman only said that it was disappointed in the announcement. Omega's first and second stage motors have already been test fired, its mobile launch platform is under construction, and its liquid hydrogen upper stage was to have been test fired in a few months.

The announcement sets the stage for US space launch during the next decade at least, since Pentagon money is a dominant engine for launch business.

Falcon 9/Starlink 1 F9

The 89th orbital Falcon 9, boosted by first stage B1051.5 on its fifth flight, launched the ninth operational group of 57 Starlink internet satellites from Kennedy Space Center on August 7, 2020, along with two rideshare BlackSky satellites. Liftoff from Launch Complex 39A took place at 05:12 UTC. The Falcon 9 second stage performed two burns to reach a roughly 380 x 400 km x 53 deg deployment orbit. BlackSky Global 7 and 8 deployment took place about an hour after liftoff, followed 30 minutes later by Starlink separation. The Starlink satellites will ultimately move themselves to 550 km operational orbits.

Total deployed payload mass was about 15.192 metric tons (tonnes), including 112 kg for the two Earth observation BlaskSky satellites. The flight increased the total number of orbited Starlink satellites, both precursor and operational, to 597, though several are being retired and deorbited. A constellation of thousands of the 260 kg, Redmond Washington-built satellites is planned.

The first stage, which previously boosted the DM-1 Crew Dragon, RCM, and Starlink 1 F3 and F6 during 2019-20, performed entry and landing burns before landing on "Of Course I Still Love You" downrange. The stage was hot-fired at LC-39A on June 24 with payload attached, but issues discovered during the test delayed the launch. On July 8 weather scrubbed a launch try and on July 11 the vehicle's third launch attempt was halted due to unspecified problems, possibly with the payload. The long-delayed flight was hop-scotched by two other Falcon 9 launches during its campaign.


CZ-2D/Gaofen 9-04

China's 50th CZ-2D orbited Gaofen 9-04, another Earth observation satellite, from Jiuquan Satellite Launcher Center on August 6, 2020. Liftoff from LC 43/94 (43/603) took place at 04:01:54 UTC. A gravity and atmospheric science microsatellite named Tsinghua was also orbited. Gaofen 9-04 separated into a roughly 500 km x 97.5 deg sun synchronous orbit.

It was the third CZ-2D/Gaofen 9 launch in 2020 to date, all from Jiuquan.

Proton Launch

Russia's Proton M/Briz M launched two communication satellites to a supersynchronous transfer orbit from Baikonur Cosmodrome, Kazakhstan on July 30, 2020. Liftoff from Site 200 Pad 39 took place at 21:25 UTC, beginning an 18 hour 16 minute mission that included five burns by the Briz M upper stage. It was the longest Proton M/Briz M mission.

Two Russian communication satellites, Ekspress 80 and Ekspress 103, were orbited. Express 80 weighed 2.11 tonnes at launch. Express 103 weighed 2.28 tonnes. Express 80 separated first at T+17 hours 59 minutes 26 seconds. Express 103 followed at T+18 hours 16 minutes 40 seconds.

Briz M fired first to reach a low Earth parking orbit. It fired again beginning at 00:29:08 (HH:MM:SS), 02:12:52, and 09:11:43 to reach GTO. Its fifth burn to reach its final orbit began at T+17:49:30.

It was the first Proton launch of the year, the 99th Proton M/Briz M, and the 424th Proton launched since the big hypergolic launch vehicle began flying in 1965.

Mars Rover Launch

Atlas 5 AV-088 launched NASA JPL's Mars-2020 mission with the Perserverance rover toward Mars from Cape Canaveral, Florida on July 30, 2020. Liftoff from Space Launch Complex 41 took place at 11:50 UTC. The Atlas 5-541 dropped its four solid motor boosters 1 min 50 sec after liftoff, shed its payload fairing at T+3:28, and shut down its Russian RD-180 first stage engine at T+4:22. The Centaur second stage fired its RL10C-1 engine for 7 min 1 sec to reach a parking orbit, then restarted at T+45:21 over the Indian Ocean for a 7 min 38 sec burn that propelled the roughly 4,082 kg payload into solar orbit. Mars-2020 separated at T+57:42.

Mars-2020 includes a Cruise Stage, Aeroshell, Descent Stage, the 1,025 kg Perserverance Rover, and a Heat Shield. Riding along with the RTG-powered rover is the 1.8 kg Ingenuity helicopter, which will attempt to fly above the surface of Mars.

It was the third Mars-bound launch in recent weeks, all taking advantage of this bi-annual Earth-Mars alignment. AV-088 was the fifth Atlas 5 launch toward Mars, a total that includes NASA’s Mars Reconnaissance Orbiter in 2005, Curiosity rover in 2011, MAVEN orbiter in 2013 and InSight lander in 2018.

ZY-3 Launch

Chang Zheng 4B number Y45 orbited Ziyuan 3-3 and microsatellite Tianqi 10 from Taiyuan Satellite Launch Center on July 25, 2020. The three-stage, 249 tonne hypergolic propellant rocket lifted off from LC 9 at 03:17 UTC. The third stage inserted the 2.63 tonne high resolution civil remote sensing satellite into a roughly 505 km x 97.4 degree sun synchronous orbit. Tianqi, an 8 kg communication microsatellite for IoT communications, likely entered a similar orbit.

During ascent the second stage, after completing its burn and separating from the rocket, performed a maneuver to steer itself toward a small drop zone. The third stage lowered its orbit after inserting the satellites, likely through use of a RCS and propellant blow down.

It was the second CZ-4B launch of the year and the 14th DF-5 based CZ liftoff.

Progress MS-15

Russia's Soyuz 2.1a launched Progress MS-15 from Baikonur Site 31 Pad 6 on July 23, 2020. Liftoff took place at 14:26 UTC. The robot cargo hauler spacecraft flew a fast-track, two orbit ascent to the International Space Station. Progress MS-15 docked successfully and automatically after initially mis-aligning its final approach.

It was Russia's first orbital launch in two months, since May 22, an usually long gap for a country that until recent years traditionaly led the world's launch totals.

Progress MS-15 carried 1,520 kg of dry cargo, about 600 kg of propellant for transfer to ISS, 420 kg of water, and 46 kg of compressed air.

CZ-5 Tianwen 1

China launched its first Mars mission on July 23, 2020, when CZ-5 number Y4 boosted the Tianwen 1 spacecraft into solar orbit. The 870 tonne, 2.5-stage rocket lifted off from Wenchang Spacecraft Launch Site Pad 101 at 00:41 UTC. The liquid-hydrogen-fueled second stage fired its twin YF-75 engines twice to accelerate the 5 tonne spacecraft toward Mars during a roughly 36 minute mission.

Ascent times were as follows. Booster separation T+175 seconds, shroud separation T+362 seconds, Staging T+492 seconds, Stage 2 cutoff T+702 seconds, Stage 2 restart T+1,165 seconds and shutdown at T+2,010 seconds, vernier cutoff T+2,107 seconds, and spacecraft separation at T+2,177 seconds.

Tianwen means "Questions to Heaven", from a poem written by Qu Yuan roughly 2,500 years ago. China National Space Administration (CNSA), which manages the orbiter/lander/rover project, provided no live information during the flight.

Falcon 9/ANASIS 2

The 68th orbital Falcon 9 v1.2 flight attempt launched ANASIS 2 (Army/Navy/Air Force Satellite Information System) for South Korea's military from Cape Canaveral on July 20, 2020. Liftoff from SLC 40 took place at 21:30 UTC. Falcon 9's second stage performed two burns during the roughly half-hour flight to insert the Airbus-built Eurostar E3000 series communications satellite into an unknown elliptical (likely supersynchronous) transfer orbit. ANASIS 2, which likely weighed 3.5 to 5 tonnes at liftoff, will presumably raise itself to geosynchronous orbit where it will operate. First stage B1058.2, which previously boosted the first NASA commericial crew mission on May 30, 2020, performed entry and landing burns to land on "Just Read the Instructions" downrange in the Atlantic Ocean.

B1058.2 performed a static test firing at SLC 40 on July 11, 2020 with no payload attached to the top of the rocket. At the time, plans called for a July 14 liftoff. That plan was stopped by a second stage problem that apparently cropped up during the combined wet dress rehearsal/static firing. The stage was either repaired or replaced prior to the final launch countdown.

Also on July 11, another Falcon 9, using first stage B1051.5 and topped by the Starlink v1-9 payload, had had its third launch attempt halted at LC 39A due to unspecified problems, possibly with the payload. That Falcon 9, which originally tried to launch nearly a month ago and has since been hop-scotched by two other Falcon 9 launches, continues to await launch.

South Korea received the satellite as part of a barter to offset that country's F-35A fighter jet purchase from Lockheed Martin. That company subcontracted the satellite to Airbus.

This was the 55th Falcon 9 launch from Space Launch Complex 40, matching the number of Titan launches (Titan 3C, 34D, Commercial Titan 3, and Titan 4) that previously took place from the site. While it took four decades for Titan to log 55 launches from (S)LC 40, Falcon 9 did it in one decade.

H-2A/Hope

Japan's H-2A launched the Emirates Mars Hope orbiter toward the Red Planet from Tanegashima Space Center on July 19, 2020. Liftoff from Yoshinobu Pad 1 took place at 21:58 UTC. Hope is the UAE's first Mars mission.

H-2A-202 F42 performed the launch. The LE-5B powered liquid hydrogen second stage performed two burns, the second beginning 56 min 39 sec after liftoff as the stage passed over the South Atlantic Ocean, to accelerate the 1,350 kg spacecraft into solar orbit. It was the first H-2A launch toward Mars.

Hope is the first of several Mars-bound launches planned for this summer.

Minotaur 4 NROL-129

Flying for the first time under the Northrop Grumman banner, a Minotaur 4 boosted four National Reconnaissance Office (NRO) satellites into orbit from Wallops Flight Facility on July 15, 2020. The NROL-129 mission lifted off from Pad 0B at 13:46 UTC after a delay to allow a boat to clear the range. It was the first Minotaur 4 launch from Wallops. A similar Minotaur 5 rose from the same pad during 2013.

Minotaur 4 uses three solid motor stages from retired Peacekeeper ICBMs, topped by a commercial Orion 38 solid motor housed in a Guidance and Control Assembly. The 85 tonne rocket lifted off on 209 tonnes of thrust from its Thiokol SR-118 first stage motor, which burned for 56 seconds. The Aerojet SR-119 124.7 tonne force second stage motor immediately ignited and extended its nozzle for its 60 second burn. The 29.5 tonne force Hercules SR-120 third stage motor coasted for ten seconds while extending its nozzle before beginning its 72 second burn. Fairing separation took place around the time of third stage ignition, which saw the end of the launch webcast. The Orion 38 fourth stage likely performed its 3.65 tonne force, 68 second burn after a roughly dozen-minute coast.

The flight aimed southeast toward a likely 43 deg inclination low Earth orbit. Minotaur 4 can lift 1.4 to 1.5 tonnes to such an orbit, depending on altitude.

Northrop Grumman (previously Orbital ATK and, before that, Orbital Sciences) conducts Minotaur 4 launches under the U.S. Space Force Orbital/Suborbital-3 contract.

KZ-11 Inaugural Failure

China's Kuaizhou 11 failed to orbit two small satellites during its inaugural flight from Juiquan Satellite Launch Center on July 10, 2020. Liftoff from a mobile transporter launcher parked on a flat pad took place at 04:17 UTC. The first minutes of flight look nominal through second stage separation, but an unknown failure occurred before orbit could be attained.  The ascent was planned to include a long coast phase to an insertion more than an hour after launch.

KZ-11, managed by Expace Technology and developed by China Aerospace Science & Industry Corp (CASIC), is a three stage solid-motor launch vehicle that is topped by a liquid "Propulsion Control Module". It is likely derived from China's DF-31 intercontinental ballistic missile. KZ-11 is 2.2 meters diameter, weighs 78 tonnes at liftoff, and is capable of placing 1 tonne in a 700 km sun synchronous orbit.

The payload included 230 kg BilibiliSat and 97 kg Xiangrikui 2, which were lost in the failure.

KZ-11 is the latest in a string of new launch vehicles developed in China since 2013 that are based on solid propellant missiles. These include the successful CZ-11 and KT-2, both DF-31 based, the successful DF-21/25 based KZ-1(A), and the so-far unsuccessful DF-26 based ZQ-1. KT-1, an early solid-motor design, failed in two attempts during 2002-2003.

CZ-3B/APStar 6D

China's Chang Zheng 3B boosted the APStar 6D communications satellite to geosynchronous transfer orbit from Xichang Satellite Launch Center on July 9, 2020. Liftoff of "Enhanced" CZ-3B number Y64 from LC 3 took place at 12:10 UTC. The liquid hydrogen third stage performed two burns during the roughly half-hour mission.

The 5.55 tonne DFH-4E satellite was built by the China Academy of Space Technology. It will be operated by APT Satellite Company Ltd. The satellite will provide Ku/Ka-band broadband internet communications from geosynchronous orbit at 134 degrees East, after raising itself to that orbit.

It was the 13th DF-5 based orbital launch of the year and 12th success. It was also the 5th beyond-LEO attempt and 4th success, more than any other launch vehicle family despite an April CZ-3B failure.

Shavit-2 Spysat Launch

Israel's Shavit-2 rocket launched Ofeq 16, an electro-optical reconnaissance satellite, into a retrograde low earth orbit from Palmachim Air Base on July 6, 2020. Liftoff of the 32.9 tonne launch vehicle took place at 01:00 UTC. Ofeq 16, built by Israel Aerospace Industries (IAI Ltd), was boosted into a retrograde low Earth orbit. It was the first Shavit-2/Ofeq launch since Ofeq 11 was successfully launched in 2016, but then suffered problems in orbit.

The launch was jointly carried out by IAI and the Defense Ministry’s Space Administration, which is a part of the Administration for the Development of Weapons and Technological Infrastructure. It may have been the 12th Shavit launch attempt since 1988.

Rarely-flown Shavit consists of three solid fuel motor stages topped by an optional liquid fuel fourth stage. Payloads of only 250-300 kg are possible due to the fact that the rocket must launch toward the west across the Mediterranean Sea, toward the Straits of Gibralter, from Palmachim Airbase on Israel's coast. The resulting westward, or retrograde orbit, reduces payload mass compared to an eastward launch that would gain free velocity from the Earth's rotation.

CZ-2D Launch

China's Chang Zheng (Long March) 2D Y29 orbited Shiyan Weixing 6-02 from Jiuquan Satellite Launch Center on July 4, 2020. Liftoff from Site 43 Pad 603 took place at 23:44 UTC. The satellite was inserted into a roughly 700 km x 98.19 deg sun synchronous orbit.

The mission of Shiyan Weixing 6-02 was vaguely described by offical new reports from China to be for "space environmental exploration and related technical tests".

It was the 12th DF-5 based orbital launch of the year, more than any other launch vehicle family.

Electron Fails

Rocket Lab's 13th Electron, named "Pics Or It Didn’t Happen’", failed to reach orbit with seven small satellites on July 4, 2020. Liftoff from Mahia, New Zealand's LC 1 took place at 21:19 UTC. The flight appeared normal through the first stage burn, staging, second stage engine start, and fairing separation. At about T+5 minutes 42 seconds, however, about 45 seconds before the planned second stage battery hot-swap that would have transferred second stage engine turbopump power to a second battery, video downlink ended and acceleration appeared to cease. The second stage normally would have burned until the 9 minute 2 second mark to place the Curie third stage into a parking orbit.

The primary payload was Canon Electronics CE-SAT-IB with experimental imaging equipment, five Planet SuperDove imaging satellites, and one In-Space 6U CubeSat named Faraday 1.

Rocket Lab confirmed that the vehicle was lost soon after its webcast ended. The company vowed that it would find the problem and return to flight soon. The failure came after 11 consecutive Electron successes.

CZ-4B Launch

China's CZ-4B, tail number Y-43, orbited a high resolution imaging satellite from Taiyuan Satellite Launch Center on July 3, 2020. Liftoff from LC 9 took place at 03:10 UTC. The 2.4 tonne satellite, CAST's first "GF" series multi-mode "civil" optical imaging satellite, was inserted into a sun synchronous orbit. A student microsatellite named Xibaipo or Bayi 02 also rode to orbit during the launch.

It was the first CZ-4B launch of the year and the 11th DF-5 based CZ orbital launch of 2020.

GPS 3-3

SpaceX Falcon 9 performed its second GPS 3 mission on June 30, 2020, boosting Global Positioning System 3 Space Vehicle 3 into a medium transfer orbit from Cape Canaveral, Florida. The 88th Falcon 9 to fly rose from Space Launch Complex 40 at 20:10 UTC with the Lockheed-Martin-built payload, beginning a 1.5 hour mission that included two ascent burns by the second stage. SpaceX recovered first stage B1060.1 on "Just Read the Instructions" after it performed ascent, entry, and landing burns.

During its previous, GPS 3-1 launch in 2018, Falcon 9's first stage was expended while lofting its 4.4 tonne payload to a roughly 1,200 x 20,200 km x 55 deg orbit. On this flight, the U.S. Space Force gave up some payload mass and orbital energy to allow first stage recovery, with 4.311 tonne GPS 3-3 inserted into a 400 x 20,200 km x 55 deg orbit.

Mission times were MECO at 2:31 follow by staging at 2:35. The second stage fired from 2:42 until 8:07 to reach a parking orbit. Fairing separation took place at 3:28. The first stage completed its entry burn at 6:45 and landing burn at 8:30. Stage 2 coasted until restarting at 1:03:28 for a 45 second transfer orbit insertion burn. The stage and payload coasted for 25 more minutes before GPS 3-3 separated.

The rocket stages were test fired at McGregor, Texas, likely during March, 2020. The assembled rocket performed a first stage static test firing at SLC 40 on June 25.

China Navsat Complete

China's CZ-3B/E, serial number Y68, boosted 4.6 tonne Beidou 3 GEO-3 (Beidou 55) into geosynchronous transfer orbit from Xichang Satellite Launch Center on June 23, 2020. Liftoff from Pad 2 took place at 01:43 UTC. The launch, which took place after a June 13 attempt was scrubbed by a third stage vent valve issue, completed the Beidou 3 navigation satellite constellation.

It was the first CZ-3B launch since a failed April 9, 2020 attempt to orbit Palapa N1. That vehicle's liquid hydrogen fueled third stage suffered a failure during its first burn.

CZ-2D Launch

China's CZ-2D, serial number Y52, orbited high resolution Earth imaging satellite Gaofen 9-03, along with two microsatellites, from Jiuquan Satellite Launch Center on June 17, 2020. Liftoff from LC 43/603 (also called 43/94) took place at 07:19 UTC. The two-stage, hypergolic propellant rocket inserted the satellites into sun synchronous low earth orbit.

The small satellites included Pixing-3A - a Zhejiang University experimental pico/nano-satellite test, and HEDE-5 - a Beijing Hede Aerospace Technology Co., Ltd. ship tracking satellite.

It was the ninth DF-5 based launch of 2020.

Falcon 9/Starlink 1 F8

The 88th Falcon 9, boosted by first stage B1059.3 on its third flight, launched the eighth operational group of 58 Starlink internet satellites from Cape Canaveral on June 13, 2020, along with three rideshare PlanetLabs satellites named Skysat 16-18. Liftoff from Space Launch Complex 40 took place at 09:15 UTC. The Falcon 9 second stage performed a single, roughly 6 minute 10 second ascent burn to directly reach an elliptical deployment orbit where, about 13 minutes after liftoff, Skysat deployment took place. The Starlink satellites separated about 13 minutes later. They will ultimately move themselves to 550 km operational orbits. This was the fifth direct ascent Starlink flight.

Total deployed payload mass was about 15.41 metric tons (tonnes), including 330 kg for the three Skysats. The flight increased the total number of orbited Starlink satellites, both precursor and operational, to 540, though about a dozen or more of previously launched satellites are being retired and deorbited. A constellation of thousands of the 260 kg, Redmond Washington-built satellites is planned.

The first stage, which previously boosted CRS-19 and CRS-20 to ISS during 2019-2020, performed entry and landing burns before landing on "Of Course I Still Love You" downrange. SpaceX chose not to hot fire the first stage at SLC 40 before the launch, possibly the first time such a static test has been bypassed by the company. Both payload fairing halves had also previously flown, one on the JCSAT-18/Kacific1 mission and the other on Starlink v1.0 F2.

Electron Launch

Rocket Lab's twelfth Electron launched five microsatellites on a rideshare mission from New Zealand on June 13, 2020. Liftoff of the "Don't Stop Me Now" mission from Mahia Peninsula LC 1 took place at 05:12 GMT. Payloads included three U.S. National Reconnaissance Office (NRO) satellites, a University of New South Wales "M2 Pathfinder" communications experiment satellite for the Australian military, and a NASA Boston University Cubesat mission named ANDESITE designed to measure plasma currents in orbit.

The launch had been delayed from March 30 when New Zealand's government implemented shut-down orders for most businesses to slow the COVID-19 pandemic.

Electron's first stage fired its nine battery-powered Rutherford LOX/Kerosene engines for 2 min 36 sec before shutting down and separating. The second stage vacuum Rutherford burned for 6 min 10 sec to reach an elliptical transfer orbit, performing a battery "hot-swap" after the first 3 min 49 sec of the burn. Payload fairing separation took place at T+3 min 12 sec. After a half-orbit coast, the Curie third stage fired its engine for 1 min 36 sec to circularize the orbit. Payload deployments occurred about one hour after liftoff.

CZ-2C Oceansat Launch

China's CZ-2C launched Haiyang 1D, fourth in an ocean survey satellite series, into orbit from Taiyuan Satellite Launch Center on June 10, 2020. Liftoff from LC 9 took place at 18:31 UTC. The two stage, 192 tonne, hypergolic propellant rocket boosted the 442 kg satellite into a sun synchronous low Earth orbit. HY-1D will form China's first marine civil service satellite constellation in conjunction with already-orbited HY-1C.

It was the year's 40th known orbital launch attempt worldwide, and the 36th success.

Falcon 9/Starlink 1 F7

The 65th Falcon 9 v1.2 to fly, boosted by first stage B1049.5 on its fifth flight, launched the seventh operational group of 60 Starlink internet satellites from Cape Canaveral on June 4, 2020. Liftoff from Space Launch Complex 40 took place at 01:25 UTC. The Falcon 9 second stage performed a single, roughly 6 minute 12 second ascent burn to directly reach a roughly 213 x 365 km x 53 deg deployment orbit where, about 15 minutes after liftoff, the 60-satellite stack separated. The satellites were expected to subsequently separate from each other and move themselves to 550 km operational orbits. This was the fourth direct ascent Starlink flight.

Total deployed payload mass was about 15.6 metric tons (tonnes). The flight increased the total number of orbited Starlink satellites, both precursor and operational, to 482, though about a dozen of the precursor satellites are being retired and deorbited. A constellation of thousands of the 260 kg, Redmond Washington-built satellites is planned.

The first stage, which previously boosted Telstar 18 VANTAGE, Iridium-8, Starlink 0.9, and Starlink 1-2 during 2018-2020, performed entry and landing burns before landing on a refurbished "Just Read the Instructions" downrange. It was the first "fifth" landing for a Falcon 9 booster. The stage was hot-fired on SLC 40 on May 13 with payload attached in anticipation of a May 17 launch, but a tropical depression affecting the landing zone forced the launch to be delayed behind the Demo 2 crew launch mission.

The launch took place on the 10th anniversary of the first Falcon 9 launch, also from SLC 40. There have been a total of 85 orbital Falcon 9 launches, three Falcon Heavy flights, and one suborbital Falcon 9, with an 87th Falcon 9 lost during a prelaunch accident. Falcon 9 launches included 5 "v1.0" Merlin 1C powered types, 15 "v1.1" Merlin 1D types, and 65 "v1.2" Merlin 1D types with stretched second stages. A v1.2 Falcon 9 was lost during the September 2016 pad accident along with its AMOS 6 payload.
