Spacex falcon 9 launch dec 15 201712/4/2023 ![]() Stage 1 (str., reusable) / 9 × Merlin-1D (upr.) Some later flights might also use a floating barge for landing, if performance requires it. The first mission of the Falcon-9 v1.2 performed a successful landing of the first stage on land. The first landings on a barge was tried on the Dragon CRS-5 and Dragon CRS-6 missions, but both failed. ![]() In 2013, the enlarged Falcon-9 v1.1 took over, featuring higher powered Merlin-1D engines in a new octagonal arrangement and larger tanks. The first flight for a Falcon-9 v1.0 took place in June 2010. The Falcon-9 will also lift the Dragon space capsule for ISS cargo flights, which has also been developed into a crewed spacecraft. An additional launch site at Boca Chica near Brownsville, Texas, was also under construction, but this site has in 2018 been dedicated for the Starship development. High inclination launches will launch from Vandenberg AFB. Launch site for low inclination launches is Cape Canaveral launch pad SLC-40. ![]() The Falcon-9 is offered with a 5.2 m fairing. The upper stage uses a single Merlin engine and will also be potentially reusable. The first stage, which is potentially reusable after recovery by parachutes (v1.0) or by powered landing (v1.1 and later), is powered by 9 of the SpaceX built Merlin-1C (v1.0) or Merlin-1D (v1.1) engines with regenerative cooling. It is technologically based on the Falcon-1 launch vehicle. Falcon-9 is a liquid fueled orbital launch vehicle for medium to heavy sized missions, which is developmened by SpaceX (Space Exploration Technologies Corp.).
