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).
A Falcon 9 v1.0 being launched with a Dragon spacecraft to deliver cargo to the ISS in 2012. F9 v1.0 was an expendable launch vehicle developed from 2005 to 2010. It flew for the first time in 2010. V1.0 made five flights, after which it was retired. The first stage was powered by nine Merlin 1C engines arranged in a 3 × 3 grid.
The Falcon 9 v1.1 features stretched first and second stages, and a new octagonal arrangement of the 9 Merlin-1D engines on the first stage (replacing the square pattern of engines in v1.0). SpaceX notes that the Falcon 9 v1.1 is cheaper to manufacture, and longer than v1.0.
It was first fired with a full mission duty firing in 2007, [4] first flew on the third Falcon 1 mission in August 2008, [5] powered the "first privately-developed liquid-fueled rocket to successfully reach orbit" (Falcon 1 Flight 4) in September 2008, [5] and subsequently powered the first five Falcon 9 flights — each flown with a version 1. ...
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 ...
SpaceX was planning to develop a 560 kN (130,000 lbf) version of Merlin 1C to be used in Falcon 9 Block II and Falcon 1E boosters. [23] This engine and these booster models were dropped in favor of the more advanced Merlin 1D engine and longer Falcon 9 v1.1 booster. Merlin 1C Vacuum engine at Hawthorne factory in 2008
Designed and operated by SpaceX, the Falcon 9 family includes the retired versions Falcon 9 v1.0, v1.1, and v1.2 "Full Thrust" (blocks 3 and 4), along with the active Block 5 evolution. Falcon Heavy is a heavy-lift derivative of Falcon 9, combining a strengthened central core with two Falcon 9 first stages as side boosters. [1]
