Falcon 9 is a partially reusable, 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.

The payload fraction is the quotient of the payload mass and the total vehicle mass at the start of its journey. It is a function of specific impulse, propellant mass fraction and the structural coefficient. In aircraft, loading less than full fuel for shorter trips is standard practice to reduce weight and fuel consumption.
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
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 .
As of 2023, SpaceX and NASA are the only launch providers which have achieved first-stage reuse of an orbital vehicle with SpaceX’s two-stage Falcon 9 and 2.5-stage Falcon Heavy, and NASA’s Space Shuttle Solid Rocket Boosters. Rocket Lab has recovered multiple first stages of their Electron rocket, but has not flown them again.
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. [citation needed] The interstage mounting hardware was changed after B1056. The newer interstage design ...
A drag count is a dimensionless unit used by aerospace engineers. 1 drag count is equal to a of 0.0001. [ 1 ] [ 2 ] As the drag forces present on automotive vehicles are smaller than for aircraft, 1 drag count is commonly referred to as 0.0001 of C d {\displaystyle C_{d}} .
A similarly designed Falcon 5 rocket was also envisioned to fit between [22] the Falcon 1 and Falcon 9, but development was dropped to concentrate on the Falcon 9. [ 21 ] The first version of the Falcon 9, Falcon 9 v1.0 , was developed in 2005–2010, and flew five orbital missions in 2010–2013.
