NASA tries to get the private section into the rocket-launching business by awarding a total of about $500 million to two companies to develop low-cost flights to the International Space Station.
Under the Commercial Orbital Transportation Services (COTS) Program, SpaceX and Rocketplane Kistler will only be paid after the companies reach specified goals along the way. The first stage of the program involves sending cargo to the International Space Station. The second stage requires sending and returning crews.
Right is Dragon, the capsule that SpaceX plans to develop.
