In the second of two demonstrations under that contract, SpaceX delivered cargo to the orbital outpost in May, 2012 using its Dragon capsule launched atop its Falcon 9 booster rocket.
SpaceX will fly 12 logistics missions to the station under its 1.6 billion Commercial Resupply Services contract awarded in 2008. The first of those flights is scheduled for no earlier than Oct. 5, 2012.
NASA is still waiting for its second cargo services provider, Orbital Sciences Corp., to wrap up its own demonstration program. Orbital holds a 1.9 billion contract to make eight deliveries to the space station with its Cygnus space freighter and Antares launcher.
Orbital has two flight demonstrations scheduled: the Antares maiden flight, in which the rocket will carry a ballast payload; and a mission with the full Antares/Cygnus stack. These demonstrations are scheduled for October and December, 2012 the company says.
