Falcon-9 is a liquid fueled orbital launch vehicle for medium to heavy sized missions, which is currently under development at SpaceX (Space Exploration Technologies Corp.). It is techonologically based on the Falcon-1 launch vehicle. Both stages are Kerosene / LOX fueled.
The first stage, which will be reusable after recovery by parachutes, is to be powered by 9 of the SpaceX built Merlin-1C engines with regenerative cooling. The upper stage will use a single Merlin engine and will also be reusable. The Falcon-Heavy is offered with a 5.2 m fairing.
High inclination launches will launch from Vandenberg AFB. Launch site for low inclination launches is Cape Canaveral. An additional launch site near Brownsville, Texas, is also under consideration.
The first flight for a Falcon-Heavy is planned for 2014 from Vandenberg.
