Falcon 9 v1.2. Flight Log

First "Full Thrust" First Stage Hot Fire Test on September 21, 2015

During January, 2015, Martin Halliwell, SES chief technical officer, revealed that SpaceX was introducing a higher-thrust modification of its Merlin 1D engine, with about 20% more thrust, and that SES was deciding whether or not to be the first to fly with the new engine. The company was thinking about skipping its then-planned Spring 2015 launch slot to allow someone else to fly the "full-thrust" engine first.

That is how the world learned about plans for an upgraded Falcon 9, eventually to be known as Falcon 9 v1.2.

Elon Musk made it official on March 1, 2015, when he stated that Falcon 9 upgrades were planned that would allow for first stage landings during geosynchronous transfer missions. The upgrades would include a 15% increase in thrust, the use of "deep cryogenic", or "densified", liquid oxygen, and a 10% second stage tank volume increase.

Mr. Musk did not name the upgraded rocket at that time, so industry observers began identifying it as "Falcon 9 v1.2".

On March 9, Aviation Week & Space Technology reported that SES had decided, after all, to be the first "full thrust" Falcon 9 customer. SES 9, a communications satellite, would launched to geosynchronous transfer orbit by the new rocket during the second or third quarter of 2015. SES CEO Karim Michel Sabbagh announced the decision.

On March 17, 2015, SpaceX President Gwynne Shotwell offered more details about the upgraded rocket. She said that the company had gone back to certify extra performance from Merlin 1D. She said "I don't know what we're going to call it. Enhanced Falcon 9, Falcon 9 v1.2, Full-Performance Falcon 9" - indicating that the company still had not decided on a name.

She said that the upgraded rocket would provide "about a 30% increase in performance, maybe a little more", while also allowing the first stage to be landed on a downrange ship platform during GTO missions.  The payload mass cutoff point for first stage return was not announced.  Without first stage return the new rocket may be able to boost more than 6 tonnes to GTO.

Shotwell also said that the upgraded Falcon 9 first stage would essentially be used as a side booster for Falcon Heavy, while the Falcon Heavy core would be a different design.

The announced upgrade meant that Falcon 9 would now lift off on 694 tonnes of sea level thrust rather than the previous 600 tonnes. Second stage Merlin 1D Vacuum thrust would increase to at least 95 tonnes force. The second stage engine would also use a longer nozzle to improve specific impulse, requiring a stretch of the interstage.

During the summer of 2015, SpaceX continued to send mixed signals about the upgraded rocket's name. One presentation by SpaceX during the summer of 2015 identified it as "Falcon 9 Upgrade".  During September, 2015 the company began calling it "Falcon 9 v1.1 Full Thrust". By early 2016 that name had been dropped, apparently in favor of "Falcon 9 v1.2", which was the name filed with the FAA.

A test program involving "full thrust" Merlin engines was completed at McGregor, Texas during the summer. Meanwhile, the first "Full Thrust" first stage - serial production number 21 - departed the SpaceX Hawthorne, California factory at the end of August and arrived at McGregor a few days later.

On September 8, 2015, the stage was erected at the new ground-level test stand, the first stage to installed there. The stand is equipped with a below-grade flame trench. This stand, which should reduce noise imposed on neighboring communities during hot fire tests, had been completed in 2013.  It is also expected to be used for Falcon Heavy core hot fire testing.

On September 21, the stage performed a 15 second test firing. A full duration test was performed on November 19, 2015. The second stage was tested on November 22. 

The first stage arrived at Cape Canaveral during the morning of November 20.  On December 18, 2015, the first stage, topped by the second stage and integrated Orbcomm G2 payload, completed a brief static firing at SLC 40 after two days of scrubbed attempts that appeared to be ground-system related, as the test shook down new super-chilling equipment at the pad. 

As the stage entered testing, two launch sites were being prepared to handle both it and Falcon Heavy.  Space Launch Complex (SLC) 4 East at Vandenberg AFB underwent modifications that included changes to its erector transporter and the construction of a propellant densification plant.  Launch Complex 39A at the Kennedy Space Center was being totally rebuilt for Falcon Heavy and Falcon 9 v1.2, with a new horizontal processing hangar built on the former crawlerway at the base of the pad and a new pair of railroad tracks leading up to the launch pad itself.

F9-21 Liftoff

SpaceX returned its Falcon 9 to service on December 22, 2015 when it boosted 11 Orbcomm satellites into orbit from Cape Canaveral, Florida. For the first time, a Falcon 9 first stage boosted back and landed near its launch site. The landing took place at Landing Zone 1 at the former site of Launch Complex 13.

The two-stage kerosene/LOX rocket, sidelined since a June launch failure, returned in upgraded form with higher thrust engines, a stretched second stage and interstage, and supercooled, condensed propellant. The improved rocket, identified initially by SpaceX as a "Falcon 9 v1.1 Full Thrust" but later as "Falcon 9 v1.2", was the 20th Falcon 9 to fly and the 21st produced.

Liftoff from SLC 40 took place at 01:29 UTC. The now 69.799 meter (229 foot) tall rocket, about 1.524 meters (5 feet) taller than v1.1, rose on 694 metric tons (1.53 million pounds) of thrust produced by its nine Merlin 1D first stage engines. Previous Falcon 9 v1.1 first stages produced 600 metric tons (1.323 million pounds) of thrust.

f9-21b.jpg (5430 bytes)F9-21 First Stage Lands at LZ-1 About 10 Minutes After Liftoff

The first stage fired for 2 minutes 20 seconds, separating four seconds later. The second stage ignited its improved Merlin Vacuum engine at 2 minutes 35 seconds to begin a nearly eight minute burn to reach a roughly 620 x 660 km x 47 deg orbit.

The eleven 172 kg Orbcomm satellites separated in sequence from their center-mounted support pillar beginning 15 minutes and ending 20 minutes after liftoff.

Meanwhile, the first stage performed a roughly 30 second boostback burn beginning about 3 minutes 50 seconds after launch and a 20 second reentry burn about 8 minutes after launch, both using three engines. A final, roughly 32 second single-engine landing burn using only the center engine took place just before the landing, about 10 minutes after liftoff. 

The stage landed near the center of the circular landing zone.  A small fire burned at the base of the stage for at least a half-minute after the center Merlin 1D engine shut down.


f9-21c.jpg (5010 bytes)First Stage Shortly After Landing

After spacecraft deployment, the upgraded second stage Merlin Vacuum engine restarted both to test its restart capability for future missions and to deorbit the stage in the Southern Ocean south of Australia.

After the mission, Elon Musk announced that the recovered first stage would be used, if possible, for propellant loading and static fire testing at the rebuilt LC 39 Pad A.  SpaceX had no plans to re-fly the stage.   The stage was moved to the new Horizontal Integration Facility at LC 39A a couple of days after its landing, where it was photographed and inspected.

During week of January 12, the stage was unexpectedly moved to SLC 40.  A crane was used to erected it on the stand rather than the usual erector.  On January 14, an unannounced static fire attempt was made and aborted after 2-3 seconds when one of the outer engine's thrust fluctuated.  After the test, Elon Musk tweeted that the engine would be borescoped and that it might have ingested something. The stage subsequently returned to LC 39A.

Launch Complex 13 supported 51 Atlas missile and Atlas Agena orbital launches from 1958-1978. The site's mobile service tower was demolished in 2005 and its blockhouse in 2012. SpaceX subsequently built an 86 meter (282 foot) diameter landing pad centered on the spot where the original Atlas missile service tower parked during launches.



f9-22-1.jpg (12182 bytes)Falcon 9 Launches SES 9 (Updated 03/06/16)

SpaceX's second Falcon 9 v1.2 with full thrust Merlin 1D engines boosted the SES 9 communications satellite into geosynchronous transfer orbit from Cape Canaveral, Florida on March 4, 2016. Liftoff from SLC 40 took place at 23:35 UTC. The 5,271 kg Boeing BSS-702HP satellite separated about 31 minutes 24 seconds later, after two burns by the second stage Merlin 1D Vacuum engine.

SpaceX CEO Elon Musk tweeted that SES 9 had been inserted into a transfer orbit with a 40,600 km apogee. It was the first Falcon 9 Upgrade geosynchronous transfer orbit mission. The second stage used a minimum residual shutdown to provide as much orbital energy as possible, with a target of 290 km x at least 39,300 km x 28 deg. SpaceX modified earlier plans to aim for a 26,000 km apogee at the behest of SES.

The insertion change made first stage recovery very unlikely, due to its extra velocity.   SpaceX announced before the launch that it did not expect a successful recovery.   A boost-back burn was not used.  The first stage only  performed a three-engine reentry burn and a never-before-attempted three-engine final landing burn, but did not survive its high-speed attempt to land on a converted barge positioned more than 600 km downrange. The stage impacted the barge, punching a hole through the steel deck.  It was the fourth failed barge landing attempt by a Falcon 9 first stage.

The success followed scrubbed launch attempts on February 24 and 25 due to supercooled LOX temperature issues, a T-0 abort on February 28 caused by a low thrust detection in one engine, and a cancelled try on March 1 resulting from excessive high altitude winds. Prior to the launch attempts, the first stage performed a brief static fire test on February 22.



f9-23a.jpg (6223 bytes)Falcon 9 Launches CRS 8, First Stage Lands at Sea

The 23rd Falcon 9 launch vehicle, the third upgraded v1.2 variant, successfully orbited the Dragon 10 spacecraft on NASA's CRS 8 International Space Station cargo hauling mission on April 8, 2016. After performing the initial mission boost, the rocket's first stage accomplished the first successful landing on a floating platform - the company's converted landing barge - positioned about 300 km northeast of the Cape Canaveral Space Launch Complex 40 launch site. It was the fifth such attempt.

Liftoff took place at 20:43 UTC after no delays or scrubs.  Dragon was targeted toward a 200 x 360 km x 51.6 deg orbit. The spacecraft carried 3,136 kg of cargo, including the 1,413 kg Bigelow Expandable Activity Module (BEAM) experiment in the unpressurized trunk section. At more than 8.6 tonnes, the combined Dragon and cargo mass was the heaviest-payload yet launched by a Falcon 9.

f9-23b.jpg (11046 bytes)F9-23 First Stage After Landing

During its descent, the first stage perform a three-engine boost-back burn, followed by a final single-engine landing burn.   Landing took place about 8 minutes 35 seconds after liftoff.

The F9-23 first stage had performed a static firing at SLC 40 on April 5.  After its successful static testing at McGregor, Texas during February, a ground equipment failure damaged multiple engines during a non-propulsive test.  The engines were repaired or replaced without causing significant delay to the launch schedule.

Dragon arrived at ISS on April 10, 2016. 

The landing platform with the first stage returned to Port Canaveral during the pre-dawn hours of April 12, 2016.  During the day, a crane picked up the stage from the barge and placed it onto a work stand on the dock.   After several days of processing which included leg removal, the stage was moved to the Launch Complex 39A HIF on April 19.


New Falcon 9 Performance Numbers Revealed

On April 30, 2016, SpaceX released new performance data for an improved Falcon 9 v1.2.  The two-stage rocket gross mass increased to about 564 tonnes, not including payload, and its liftoff thrust rose to 775.65 tonnes as Merlin 1D thrust was pushed upward again to 190,000 pounds (86.183 tonnes) at sea level.  For the first time, the company gave solid payload performance numbers for this version.  They were:  22.8 tonnes to LEO x 28.5 deg, 8.3 tonnes to GTO x 27 deg, and 5.5 tonnes GTO x 27 deg when the first stage was recovered downrange.  The cost for a flight with first stage recovery was listed at $62 million. 

By early 2017 it had become apparent that SpaceX referred to this improved version as "Falcon 9 Block 5".   Block 5 was designed to perform Dragon 2 Commercial Crew launches for NASA, but would also apparently be used for unmanned satellite launches.  Elon Musk announced that the first Block 5 launch would occur by the end of 2017. 

It had also become known that the company was, as of late 2016/early 2017, still flying "Falcon 9 Block 3".  Block 3 thus was the Falcon 9 v1.2 variant.  The identity of "Block 4" was, as of early March 2017, unknown outside the halls of SpaceX.

f9-29x.jpg (13538 bytes)Falcon 9 and AMOS 6 Destroyed in Pre Launch Test

Screen Capture from USLaunchReport.com Video of F9-29 Explosion

A Falcon 9 rocket and its $200 million AMOS 6 satellite payload were destroyed during a pre-launch propellant loading and hot fire test exercise at Cape Canveral on September 1, 2016.  The test was planned to assure all was ready for a September 3 launch that would have placed 5.5 tonne AMOS 6 in geosynchronous transfer orbit. 

Early reports indicated that propellant loading was nearly completed and the test was about eight minutes away when a powerful explosion destroyed the rocket and satellite at about 9:07 AM Eastern Time.  A series of smaller explosions occurred during the following minutes as a fire raged at SLC 40 and a large plume of black smoke drifted across the Florida space center.  It was the largest pad explosion in the history of Cape Canaveral/Kennedy Space Center.

A few hours after the explosion, Elon Musk tweeted that the failure appeared to have begun at the second stage liquid oxygen tank.  SLC 40 was reported to have been heavily damaged, knocking it out of service.  A day after the failure, SpaceX announced that East Coast launch campaigns would move to Kennedy Space Center Launch Complex 39 Pad A, which at the time was planned to be ready to support operations beginning in November, 2016.   

The AMOS 6 launch would have been the 29th Falcon launch, and the ninth by a Falcon 9 v1.2 variant.  The AMOS 6 first stage was test fired at McGregor, Texas on August 5, 2016 and arrived at Cape Canaveral some time after August 21. 

SpaceX subsequently determined that the cause was sudden overpressurization of the second stage liquid oxygen (LOX) tank due to the failure of a composite overwrapped pressure vessel (COPV) containing pressurized helium that was mounted inside the LOX tank.  Improper control of subcooled-LOX temperatures may have been involved.  Elon Musk suggested that LOX froze within or beneath the composite overwrapping, causing loss of COPV structural integrity.  SpaceX performed cryogenic loading tests, with some leading to failure, of small test vessels at its McGregor, Texas test site to confirm the failure mode.   

f9-30.jpg (10368 bytes)Falcon 9 Returns to Flight

Ending a four-month failure investigation stand-down, SpaceX Corporation's Falcon 9 launch vehicle returned to service on January 14, 2017, orbiting ten IridiumNEXT satellites from Vandenberg AFB in California. The v1.2 variant, informally designated F9-30 by outside observers (it used first stage number B1029), lifted off from Space Launch Complex 4 East at 17:54 UTC to begin a hour-long mission that inserted the 860 kg, Thales Alenia Space-built satellites into roughly 610 x 620 km x 86.4 deg orbits. The satellites will raise themselves into 780 km operational orbits.

After a 43 minute, 16 second coast, the Falcon 9 second stage restarted for a brief second, circularization burn at first apogee about 52 minutes 31 seconds after liftoff to complete the powered phase of the flight. Spacecraft separation began at about the 59 minutes 16 seconds mark, with each satellite separating individually separated by about 1.5 minutes.

The first stage performed boost-back, reentry, and landing burns before landing on the converted barge "drone ship" “Just Read the Instructions”. It was the first successful first stage landing in two West Coast attempts. Six previous first stage recoveries had been made after Cape canaveral liftoffs.

The launch was the first of seven planned IridiumNext Falcon 9 flights that will replace the company's orbiting "Little LEO" communication satellite constellation.

Falcon 9 had been grounded since F9-29 and its $200 million AMOS 6 satellite payload were destroyed during a pre-launch propellant loading and hot fire test exercise at Cape Canveral on September 1, 2016. SpaceX determined that the cause was sudden overpressurization of the second stage liquid oxygen (LOX) tank due to the failure of a composite overwrapped pressure vessel (COPV) containing pressurized helium that was mounted inside the LOX tank. Improper control of subcooled-LOX temperatures may have been involved. Elon Musk of SpaceX suggested that LOX froze within or beneath the composite overwrapping, causing loss of COPV structural integrity.

SpaceX performed cryogenic loading tests, with some leading to failure, of small test vessels at its McGregor, Texas test site to confirm the failure mode. The company also changed its propellant loading procedures, more than doubling the LOX loading time.

The F9-30 first and second stages were test fired at the company's McGregor, Texas test site during late October and early November, 2016. The first stage was hot fired at SLC 4E on January 5, 2017 after a scrub the previous day. The IridiumNEXT payload was not atop the vehicle during the wet dress rehearsal and hot fire exercise.

F9-30 was the 29th Falcon 9 launch and the ninth v1.2 variant to fly, not including the lost AMOS 6 launch vehicle. It was the first v1.2 to fly from VAFB.


f9-32a.jpg (22350 bytes)Falcon 9 Debuts from KSC

SpaceX’s Falcon 9 orbited the CRS-10 Dragon spacecraft with cargo for the International Space Station from Kennedy Space Center Launch Complex 39 Pad A on February 29, 2017.  It was the first Falcon 9 launch from the converted NASA Saturn 5/Space Shuttle launch site.  Liftoff took place at 14:39 UTC, following an aborted attempt one day earlier caused by out of range readings from the second stage thrust vector control system. 

Falcon 9's second stage boosted Dragon into a 51.6 deg low earth orbit, with stage cutoff occurring about 9 min 5 sec after liftoff and spacecraft separation taking place about one minute later.  While the second stage was performing its 393 second long burn, the first stage did a 180 deg flip and performed 3-engine boostback burn.  It flipped again before performing a 3-engine entry burn and a single engine landing burn that began about 7 min 33 sec after liftoff.  The stage landed at Cape Canaveral Landing Zone 1, performing the first daylight landing, and third overall, at the site.  The second stage was expected to perform a deorbit burn after spacecraft separation. 

f9-32c.jpg (4631 bytes)The CRS-10 Dragon (Dragon spacecraft No. 12) carried about 2,490 kg tonnes of cargo, including 1,530 kg inside the pressurized capsule and 960 kg attached to the unpressurized trunk section.  Spacecraft berthing at ISS is scheduled to occur on February 21.  SpaceX does not announce total spacecraft mass, but based on early publications by the company and on more recent expert estimates, CRS-10 Dragon likely weighed about 8,430 kg at liftoff, including cargo.

The flight was performed by the F9-32 vehicle, a v1.2 (or "Block 3") variant, which used first stage number B1031.   The vehicle's stages were test fired at McGregor, Texas, apparently during December, 2016.   The first stage performed a brief static firing at LC 39A on February 12, 2017 after a scrubbed attempt the day before.  The first and second stages without payload were stacked for the test.

With the flight, Falcon 9 became the first launch vehicle family to perform a second orbital flight in 2017.   

For Falcon 9 and Falcon Heavy, SpaceX added a large horizontal processing hangar just south of the SLC 39A fence line and replaced the crawlerway ramp with dual rail tracks for a transporter erector launcher (TEL) to roll upon while carrying rockets up to the pad.   The flame trench was rebuilt and reconfigured, with exhaust now exiting only toward the north, and large "rainbirds" were added to spray water on the launcher during liftoff.  Additional changes to the pad are planned to support Commercial Crew launches, including installation of a crew access arm on the fixed service tower.  

Falcon Heavy is not expected to debut from LC 39A until after Cape Canaveral SLC 40 is restored to service sometime after mid-2017.   Meanwhile, SpaceX hopes to perform a first unmanned flight of its Dragon 2 Commercial Crew spacecraft from LC 39A by year's end.  An improved "Block 5" Falcon 9 being developed to launch Dragon 2 will perform the launch.

It was the 95th launch from LC 39A, a number that includes 12 Saturn 5 and 82 Space Shuttle liftoffs, the most recent by Shuttle Atlantis on July 8, 2011 for STS-135 mission.

f9-33a.jpg (9884 bytes)Falcon 9 Reflies First Stage, Orbits SES 10 (March 31, 2017 Update)

SpaceX launched a previously-flown Falcon 9 first stage for the first time on March 30, 2017. The stage, B1021, boosted the F9-33 mission that lofted the SES 10 communications satellite to geosynchronous transfer orbit from Kennedy Space Center Launch Complex 39 Pad A. B1021 had previously flown during the F9-23 CRS-8 mission on April 8, 2016, when it landed downrange on a converted barge. After a 22:27 UTC liftoff, B1021 repeated the feat, landing again on the downrange floating platform after performing reentry and landing burns.

After the first stage completed its 2 min 38 sec ascent burn, the Falcon 9 second stage fired its Merlin 1D Vacuum engine for 345 sec to reach a parking orbit. After a 17 min 55 sec coast to the equator above the west African coast, the stage restarted for 53 seconds to accelerate the 5,282 kg SES 10 satellite toward a planned 218 x 35,410 km x 26.2 deg transfer orbit. SES 10 separated from the stage 32 min 03 sec after liftoff.

After raising itself to geostationary orbit, Airbus Defense and space-built SES 10 will serve Latin America, using 55 Ku-band transponder equivalents, from 67 deg West.

After the flight, SpaceX CEO Elon Musk announced that the company had, in another first, directed one of the two payload fairing halves to a landing zone in a test of future payload fairing recovery.  The fairing had been equipped with a cold gas thruster system.  Eventually, steerable parachutes and inflatable shock absorbers will be used to bring the fairings down to recoverable ocean landings.

It was the first reflight of a complete orbital-class liquid fueled rocket stage.  Blue Origin's New Shepard rocket had previously reflown, but on much less taxing suborbital missions.  Reusable Space Shuttle orbiters brought back three main engines (SSMEs) and avionics, but expended the large external propellant tank that fed the three SSMEs.  Space Shuttle solid rocket boosters were also recovered and reused, but they were disassembled after each flight and the motor segments never stayed together to fly again as a unit.

After its 2016 flight, the B1021 stage was partially disassembled (its engines were removed, for example) and was shipped back to the SpaceX factory in Hawthorne, California.  After the engines were re-installed and other refurbishment work completed, the stage was shipped to the company's McGregor, Texas test site.  There, it was test-fired on January 25, 2017, completing what appeared to be a standard test cycle for a Falcon 9 first stage.  The new second stage was also test fired in late January or early February.  After shipment to LC 39A's Horizontal Integration Facility, the assembled F9-33 rocket performed a five-second static test at LC 39A on March 27, 2017, with no payload installed.

[8] First Falcon 9 v1.1. First VAFB SLC 4E launch of Falcon 9. 
     1st stage performed two reentry burns (3 and 1 engine), but 2nd 
     burn cutoff early due high roll rates. 2nd stage restart for 
     disposal burn failed. 
[9] First Falcon 9 GTO+ launch.  Targeted 295 x 80,000 km x 20.75 degree 
      supersynchronous transfer orbit.  Stg 1 briefly restarted post sep.
      Fire reported in Stg1 octaweb during ascent.
[A] Lower than planned fuel reserves reported at end of final Stg2 burn.
      Planned orbit achieved.
[10] First Falcon 9 fitted with extending landing legs.  First stage 
      performed two retro burns after separation, lowering itself to a 
      simulated landing in the Atlantic off the Georgia/S. Carolina coast.
[11] 2nd Falcon 9 with legs.  First stage performed two retro burns and 
      landed in Atlantic but exploded during tip over.
[12] 1st stg attempted landing on converted barge about 320 km downrange, 
      but landed hard on barge and was lost.
[13] 187 x 1,371,156 km x 37 degree insertion orbit.  DSCVR bound for Earth-Sun L1.
      Stg 1 barge landing attempt abandoned due high seas. 
[14] First stage landed hard on downrange landing platform and was destroyed.
[15] Broke up at about T+2m 19sec, before staging, due Stg2 LOX tank overpress.
[16] First stage boosted back to CC LZ-1 (former LC 13) and landed.  Performed 
      boostback, reentry, and landing burns using 3, 1, and 1 engine.  First 
      Falcon 9 v1.2 (Full Thrust) flight.
[17] First stage landed on downrange landing platform, but one leg failed to 
      lock in place.  Stage fell over and was destroyed.
[18] First stage landing on downrange platform failed.
[19] 3,136 kg cargo, incl 1,413 kg BEAM in trunk.  1st stg landed on barge 
      (1st barge success).
[20] First stage landed on downrange platform.  First GTO landing.  First 
       successful 3-engine landing.
[21] First stage landed on downrange platform.
[22] First stage destroyed during landing attempt on downrange platform.  One of 
       three engines produced low thrust during final landing burn.  Stage 
       "accordianed" on hard landing.  Mission otherwise successful.
[23] First stage landed at CC LZ-1.
[24] F9 and AMOS 6 destroyed in explosion during hot fire countdown at SLC 40. 
       Launch was planned for 09/03/16.
[25] First stage (B1029) landed downrange on drone ship "Just Read the 
       Instructions".
[26] First stage (B1031) landed at CC LZ-1.
[27] First stage (B1030) purposely expended.  No legs or fins. First 
        expendable v1.2.  Allowed heaviest-yet GTO payload. 
[28] First Stg 1 reflight using B1021.  Stage landed downrange on drone ship 
        "Of Course I Still Love You". PLF half recovery test. 
        Planned 218 x 35,410 km x 26.2 deg, but achieved agreed parameters.
[29] First stage (B1032) landed at CC LZ-1. Block 4 second stage.
[30] Expendable first stage (B1034).  Heaviest-yet GTO payload.  Stg 2 
        burned to depletion.  Block 4 second stage.
[31] First stage (B1035) landed at CC LZ-1.  1st reflight by Dragon C106.
