Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [a] designed and manufactured in the United States by SpaceX.The first Falcon 9 launch was on 4 June 2010, and the first commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012.

Rockets from the Falcon 9 family have been launched 425 times over 15 years, resulting in 422 full successes (99.29%), two in-flight failures (SpaceX CRS-7 and Starlink Group 9–3), and one partial success (SpaceX CRS-1, which delivered its cargo to the International Space Station (ISS), but a secondary payload was stranded in a lower-than-planned orbit).
The third version of the Falcon 9 was developed in 2014–2015 and made its maiden flight in December 2015. The Falcon 9 Full Thrust is a modified reusable variant of the Falcon 9 family with capabilities that exceed the Falcon 9 v1.1, including the ability to "land the first stage for geostationary transfer orbit (GTO) missions on the drone ship" [14] [15] The rocket was designed using ...
Falcon 9 v1.1 was developed in 2010–2013, and made its maiden flight in September 2013. The Falcon 9 v1.1 is 60 percent heavier, with 60 percent more thrust than the v1.0 version of the Falcon 9. [20] It includes realigned first-stage engines [21] and 60 percent longer fuel tanks, making it more susceptible to bending during flight. [20]
Falcon 9 Block 5 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [c] designed and manufactured in the United States by SpaceX. It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust .
"The SpaceX Falcon 9 vehicle may return to flight operations while the overall investigation of the anomaly during the Starlink Group 8-6 mission remains open, provided all other license ...
The Falcon 9 v1.0 first stage was used on the first five Falcon 9 launches, and powered by nine SpaceX Merlin 1C rocket engines arranged in a 3x3 pattern. Each of these engines had a sea-level thrust of 556 kN (125,000 pounds-force) for a total thrust on liftoff of about 5,000 kN (1,100,000 pounds-force).
SpaceX resumed Falcon 9 flights 15 days later. In August, another grounding was triggered by the failure of a Falcon 9 first stage to land back on Earth, a mishap that did not affect mission success.
