![]() Boosters B1023 and B1025 were Falcon 9 boosters, which were converted to Falcon Heavy side boosters for the Falcon Heavy test flight.‘The Bear’ Season 2: Let’s Talk About That Ending, Carmy’s Arc, and Providing Joy - Spoilers All boosters are Falcon 9 variants, unless otherwise noted. Since no data is provided, Falcon 9 boosters listed as simply "FT" (Full Thrust) denote Blocks 1 to 3, while Block 4 is listed as "FT Block 4". The boosters were either retired or expended after that second launch. Flights of all Falcon 9 rockets up to Block 4 were limited to 2 flights only, with a total of 14 second flights of these variants. Block 4 was a test version that included new hardware like titanium grid fins later used for the next and final major version of the Falcon 9, Block 5. Five different versions of Full Thrust have been produced, Block 1 to 4 (all retired) are found in this list while the active Block 5 is listed separately. Changes included a larger fuel tank, uprated engines and supercooled propellant and oxidizer to increase performance. ^ Mission names are presented in parentheses when applicable.įalcon 9 Full Thrust (or sometimes called Falcon 9 version 1.2) was the first version of the Falcon 9 to successfully land.Sequential numbering according to Jake Meyer's "SpaceX Data" API. ^ Exact assignment of boosters B1004–B1009 is not well documented.Two test devices made several short flights each. None of these boosters were recovered or survived landing after an orbital launch. First came some controlled water landings, then came the attempts on the drone ship "Just Read the Instructions 1". However, as the boosters broke up on re-entry due to aerodynamic forces both times, SpaceX gave up on parachutes and decided to pursue propulsive landings instead. On the maiden flight and second flight of V 1.0, SpaceX included basic recovery hardware (parachutes) to try and recover the booster. They were much smaller and had much less power. These boosters looked very different from the more recent models. These boosters were the first two major versions of the Falcon 9. All following boosters were numbered sequentially starting at B1001, the number 1 standing for first-stage booster. The first Falcon 9 version, v1.0, had boosters B0001 to B0007. Since then all boosters in the active fleet are Block 5.īooster names are a B followed by a four-digit number. The last flight of a Block 4 booster was in June 2018. Īll boosters in Block 4 and earlier have been retired, expended, or lost. This milestone was first achieved by Booster B1051 on the Starlink-27 mission in 2021. ![]() SpaceX intentionally limited Block 3 and Block 4 boosters to flying only two missions each, but the company indicated in 2018 that they expected the Block 5 versions to achieve ten flights, each with only minor refurbishment. ![]() ![]() ![]() In total 38 recovered boosters have been refurbished and subsequently flown at least a second time, the leading boosters have flown 15 missions. One of the Falcon Heavy center boosters landed softly but it was severely damaged during transport, and one mission, ViaSat-3, had its center core and side boosters fully expended, which makes it the first time the side boosters were expended. Since then, Falcon 9 first-stage boosters have been landed and recovered 203 times out of 214 attempts, including synchronized recoveries of the side-boosters of the Falcon Heavy test flight, Arabsat-6A, USSF-44, USSF-67, and STP-2 missions. After multiple attempts, some as early as 2010, at controlling the reentry of the first stage after its separation from the second stage, the first successful controlled landing of a first stage occurred on 22 December 2015, on the first flight of the Full Thrust version. The manufacture of first-stage booster constitutes about 60% of the launch price of a single expended Falcon 9 (and three of them over 80% of the launch price of an expended Falcon Heavy), which led SpaceX to develop a program dedicated to recovery and reuse of these boosters for a significant decrease in launch costs. Left to right: Falcon 9 v1.0, v1.1, v1.2 "Full Thrust", Falcon 9 Block 5, Falcon Heavy, and Falcon Heavy Block 5.Ī Falcon 9 first-stage booster is a reusable rocket booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX. ![]()
