List of Falcon 9 first-stage boosters

A Falcon 9 first-stage booster is a reusable rocket booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX. 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. 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. Since then, Falcon 9 first-stage boosters have been landed and recovered times out of attempts, including synchronized recoveries of the side-boosters of the Falcon Heavy test flight, Arabsat-6A, USSF-44, USSF-67 and STP-2 missions. One of the Falcon Heavy center boosters landed softly but it was severely damaged during transport.
In total recovered boosters have been refurbished and subsequently flown at least a second time, the leading boosters have flown 13 to 15 missions. 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. This milestone was first achieved by Booster B1051 on the Starlink-27 mission in 2021.
All boosters in Block 4 and earlier have been retired, expended, or lost. The last flight of a Block 4 booster was in June 2018. Since then all boosters in the active fleet are Block 5.
Booster names are a B followed by a four-digit number. The first Falcon 9 version, v1.0, had boosters B0001 to B0007. All following boosters were numbered sequentially starting at B1001, the number 1 standing for first-stage booster.
List of boosters.
v1.0 and v1.1.
These boosters were the first 2 major versions of the Falcon 9. The Falcon 9 looked very different from what it does today and it was much smaller and had much less power. On the maiden flight and second flight of V 1.0, SpaceX included basic recovery hardware (parachutes) to try and recover the booster. 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. First came some controlled water landings, then came the attempts on the drone ship "Just Read the Instructions 1". None of these boosters were recovered or survived landing after an orbital launch. Two test devices made several short flights each.
Full Thrust up to Block 4.
Falcon 9 Full Thrust (or sometimes called Falcon 9 version 1.2) was the first version of the Falcon 9 to successfully land. Changes included a larger fuel tank, uprated engines and supercooled propellant and oxidizer to increase performance. 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. 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. 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. The boosters were either retired or expended after that second launch.
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". All boosters are Falcon 9 variants, unless otherwise noted. Boosters B1023 and B1025 were Falcon 9 boosters, which were converted to Falcon Heavy side boosters for the Falcon Heavy test flight.
Block 5.
There are three booster types: Falcon 9 (F9), Falcon Heavy core (FH core) boosters, and Falcon Heavy side (FH side) boosters. Falcon 9 and Falcon Heavy side boosters are reconfigurable to each other. A Falcon Heavy core booster is manufactured with structural supports for the side boosters and cannot be converted to a Falcon 9 booster or Falcon Heavy side booster. The interstage mounting hardware was changed after B1056. The newer interstage design features fewer pins holding the interstage on, reducing the amount of work needed to convert a Falcon 9 booster to a Falcon Heavy side booster.
Block 5 is the latest iteration of the Falcon 9 and Falcon Heavy boosters. Changes include a stronger heat shield, upgraded engines, new carbon composite sections (landing legs, engine sections, raceways, RCS thrusters and interstage), retractable landing legs, titanium grid fins, and other additions that simplify refurbishment and allow for easier reusability. A Block 5 booster can fly more than ten times. On 11 September 2022, during the Starlink 4-2 mission, B1058 was the first to complete fourteen launches and landings to become the fleet leader. B1052, first launched in April 2019 alongside with B1053, is the oldest and earliest launched of the active Falcon 9 boosters, and has completed 7 launches and landings as of 5 September 2022. Amongst all B5 boosters, B1058 is the booster with most spacecrafts (779) launched to orbit and along with the record for most spacecraft mass launched to orbit by a single booster, that is, of ~. , SpaceX used a total of 22 new B5 boosters, of which 11 are no longer active (five have been expended and six have been lost due to failed landings or being lost during recovery).

Statistics.
Booster turnaround time.
This chart displays the turnaround time, in months, between two flights of each booster. As of April 2022 the shortest turnaround time was 21 days, for the sixth flight of B1062. Boosters that are still likely to be re-used (active fleet) are highlighted in bold and with an asterisk.
Full Thrust booster flight counts.
This chart lists how often boosters were flown. It is limited to the Full Thrust versions as previous versions were never recovered intact. The entries for Block 5 include active boosters that can make additional flights in the future. Blocks 1–3 made 27 flights with 18 boosters (1.5 flights per booster), Block 4 made 12 flights with 7 boosters (1.7 flights per booster). As of , Block 5 made flights with boosters ( flights per booster) with Falcon 9.
Block 5 booster flight status.
This chart shows the current status of Block 5 boosters that have flown; how often they have flown and whether they are still active, expended (i.e. no attempt was made to recover) or destroyed (i.e. recovery of the booster failed).
Falcon 9 FT booster timeline.
This timeline displays all launches of Falcon 9 boosters starting with the first launch of Full Thrust. Active boosters that are expected to make additional flights in the future are marked with an asterisk. Single flights are marked with vertical lines. For boosters having performed several launches bars indicate the turnaround time for each flight.
Notable boosters.
Booster 0002 "Grasshopper".
"Grasshopper" consisted of "a Falcon 9 first-stage tank, a single Merlin-1D engine" with a height of .
"Grasshopper" began flight testing in September 2012 with a brief, three-second hop, followed by a second hop in November 2012 with an 8-second flight that took the testbed approximately off the ground, and a third flight in December 2012 of 29 seconds duration, with extended hover under rocket engine power, in which it ascended to an altitude of before descending under rocket power to come to a successful vertical landing. "Grasshopper" made its eighth, and final, test flight on 7 October 2013, flying to an altitude of before making its eighth successful vertical landing. "Grasshopper" is retired.
Booster 1019.
Falcon 9 B1019 was the first Full Thrust booster, and was first launched on 22 December 2015 for Falcon 9 flight 20 and landed on the Landing Zone 1 (LZ-1). It became the first orbital-class rocket booster to perform a successful return to launch site and vertical landing.
SpaceX decided not to fly the booster again. Rather, the rocket was moved a few miles north, refurbished by SpaceX at the adjacent Kennedy Space Center, to conduct a static fire test. This test aimed to assess the health of the recovered booster and the capability of this rocket design to fly repeatedly in the future. The historic booster is currently on display outside SpaceX headquarters in Hawthorne, California.
Booster 1021.
Falcon 9 B1021 was the first booster to be re-flown and the first to land on a droneship. It was first launched on 8 April 2016 carrying a Dragon spacecraft and Bigelow Expandable Activity Module (BEAM) on the SpaceX CRS-8 mission and landed on an autonomous spaceport drone ship (ASDS). After recovery, inspections and refurbishing, it was launched again on 30 March 2017 for the SES-10 mission and recovered successfully a second time. This event marks a milestone in SpaceX's drive to develop reusable rockets and reduce launch costs. Following the second flight, SpaceX stated that they plan to retire this booster and donate it to Cape Canaveral for public display.
Boosters 1023 and 1025.
B1023 became the third orbital-class rocket to land on a droneship after launching Thaicom 8 into a geostationary transfer orbit on 30 May 2016. It was an unusually hard landing that broke the energy absorbers on at least one of the landing legs, causing the booster to "walk" across the droneship and lean over, but the rocket arrived safely at Port Canaveral. B1025 successfully launched the CRS-9 resupply mission on its maiden flight on 18 July 2016 and landed on LZ-1, being the first after B1019 to do so.
B1023 and B1025 were assigned the role of side boosters for the Falcon Heavy test flight in 2017, after which they underwent separate static fire tests. The boosters were mated to a newly built Falcon Heavy core, B1033, for the flight. The maiden flight of Falcon Heavy on 6 February 2018 launched SpaceX CEO Elon Musk's Tesla Roadster and a dummy astronaut into a heliocentric orbit passing the orbit of Mars. The boosters successfully separated from the core and performed a synchronized landing on LZ-1 and the adjacent LZ-2. B1023 is now on display at the Kennedy Space Center Visitor Complex in its Falcon Heavy side booster configuration.
Booster 1046.
B1046 was the first Block 5 Falcon 9, the final version of the SpaceX first stage. It was first launched on 11 May 2018, carrying Bangabandhu-1, Bangladesh's first geostationary communications satellite. This marked the 54th flight of the Falcon 9 and the first flight of the Falcon 9 Block 5. After completing a successful ascent, B1046 landed on the drone ship "Of Course I Still Love You". After inspection and refurbishment, B1046 was launched a second time on 7 August 2018, carrying the Telkom-4 (Merah Putih) satellite. The Telkom-4 mission marked the first time an orbital-class rocket booster launched two GTO missions. This was also the first re-flight of a Block 5 booster. Four months after the Telkom-4 mission, B1046 arrived at Vandenberg Air Force Base to support the SSO-A mission. Following delays for additional satellite checks, liftoff occurred from SLC-4E on 3 December 2018. This marked the first time that the same orbital-class booster flew three times. Its fourth and last mission launched a Crew Dragon capsule up to the point of maximum dynamic pressure, where it separated to test its abort system in flight. After separation of Falcon and Dragon, B1046 was compromised by aerodynamic forces.
Booster 1048.
B1048 was the third Falcon 9 Block 5 to fly and the second Block 5 booster to re-fly, and the first booster ever to be launched four, then five times. During the last launch, an engine shut down seconds before the planned shutdown, becoming only the second time a Merlin engine failed since the failure during the SpaceX CRS-1 in October 2012. The primary mission was unaffected and the Starlink payload deployed successfully, further confirming the reliability of the rocket due to redundancy of the engines. With reduced thrust, B1048 was unable to sufficiently slow down its descent, and thus was unable to land.
Booster 1049.
B1049 was the oldest Falcon 9 booster on active duty until its last flight on Nov 22, 2022, after which this title went to B1052. It was the first to successfully launch and land six, then seven times, and the second to launch and land eight, nine, and then ten times respectively. It launched two commercial payloads, Telstar 18V and the eighth Iridium NEXT batch, and eight internal Starlink batches. B1049 has been seen with its landing legs and grid fins removed indicating that it will be expended on its next flight. The final flight of B1049 was originally thought to be O3b mPower 4-6 but a regrouping of the launches meant that an expendable booster was no longer required. It was then originally planned that B1049's last flight would be the launch of Nilesat-301 however, plans changed and the mission was flown with a recoverable booster (B1062.7). B1049 flew the Eutelsat-10B communications satellite on November 22, 2022. This mission was its last flight.
Booster 1050.
B1050 launched for the first time on 5 December 2018. A grid fin malfunction occurred shortly after the entry burn, resulting in the booster performing a controlled landing in the ocean instead of the planned ground pad landing.
No future flights for B1050 were planned, and it was scrapped due to its damage.
Booster 1051.
B1051 was the sixth Falcon 9 Block 5 booster built. On its maiden flight on 2 March 2019, it carried a Crew Dragon into orbit on the Demo-1 mission. It then flew its second mission out of Vandenberg AFB launching the Radarsat constellation. It then flew 4 Starlink missions and launched SXM-7, totaling 5 flights in 2020 alone, and becoming the first Falcon 9 to launch a commercial payload on its seventh flight. On 18 December 2021, it flew for a record 11th time. It was the first booster to be used eight, nine, ten, eleven, and twelve times respectively. It flew for the final time on 12 November 2022 for the Intelsat G-31/G-32 mission, and was expended.
Booster 1056.
B1056 first launched on 4 May 2019, carrying a Cargo Dragon to the ISS. Because of the failure of the static test fire of Crew Dragon C204's SuperDraco abort engines on LZ-1, it landed on a drone ship instead. It flew three more times. On 17 February 2020, B1056 was planned to perform the 50th orbital-class rocket landing, just 27 days after its previous launch. The booster soft-landed in the Atlantic Ocean and was severely damaged after launching Starlink satellites into orbit, becoming the first Block 5 booster to fail landing.
Booster 1058.
Falcon 9 B1058 was first launched on 30 May 2020, from Kennedy Space Center Launch Complex 39A (Apollo 11 launch site). It carried NASA astronauts Doug Hurley and Bob Behnken to the International Space Station. It was the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission, and the first crewed flight test of Dragon 2. It was the first crewed orbital spaceflight by a private company. The booster is the first and currently only Falcon 9 booster to feature NASA's worm logo, which was reintroduced after last being used in 1992. On 11 September 2022, it flew for the 14th time and became the first booster to be recovered 14 times. On 17 December 2022, it was also the first booster to fly and land for the 15th time.
Booster 1061.
Falcon 9 B1061 first launched Crew-1 to the ISS in November 2020, the first operational flight of Crew Dragon, and landed on a drone ship. It became the first booster to fly crew twice as well as the first reused booster to fly crew as a part of the Crew-2 mission. This first stage went on to complete additional missions. B1061 is the only booster to land on all of SpaceX's different landing zones and drone ships, except LZ-2.
Booster 1062.
Falcon 9 B1062 launched Inspiration4 in 2021, operated by SpaceX on behalf of Shift4 Payments CEO Jared Isaacman. The mission launched the Crew Dragon "Resilience" on 16 September 2021 at 00:02:56 UTC from the Florida Kennedy Space Center's Launch Complex 39A atop a Falcon 9 launch vehicle, placed the Dragon capsule into low Earth orbit, and ended successfully on 18 September 2021 at 23:06:49 UTC, when the "Resilience" splashed down in the Atlantic Ocean. B1062 currently holds the record for the fastest booster turnaround time at 21 days and 4 hours between 8 April 2022
(Axiom-1) and 29 April 2022 (Starlink Group 4–16) beating the previous record of 27 days and 6 hours held by B1060. This was the first time a booster had flown twice in the same month. According to the SpaceX webcast of the Starlink Group 4-16 mission, the booster spent just 9 days in refurbishment.
Booster 1069.
Falcon 9 B1069 launched SpaceX CRS-24 to ISS in December 2021 for NASA. SpaceX achieved the feat of 100 successful orbital rocket booster landings in this mission, coinciding with the 6th anniversary of its first booster landing. The rough seas led to the Octograbber robot not being able to secure the booster to the deck, leading to both the booster, dronseship and the Octagrabber robot being heavily damaged in transit. It took months for SpaceX to refurbish B1069, returning into service only on Group 4-23 mission in August 2022.
On its next flight for Eutelsat Hotbird 13F, B1069 included a hosted promotional payload by FIFA, that was a box powered by starlink containing 2 Adidas Al Rihla (the Journey) balls, that were to be used in 2022 FIFA World Cup in Qatar. These match balls were launched and brought back by landing on the droneship surviving the stresses of the booster. Later, they were taken out and shipped back to Qatar for the world cup. This was actually the first payload on a Falcon 9 booster and thus showed the ease of reusability. The balls' flight by SpaceX was, in part, a promotion for the company's Starlink satellite internet service. An associated website invited World Cup attendees to visit the Starlink office in Doha.
