NASA, SpaceX sign cargo launch agreement

Impressed with the progress shown by the commercial spaceflight industry, NASA signs agreements with SpaceX, a venture started by PayPal founder Elon Musk, and Oklahoma-based Rocketplane Kistler (RPK) to begin developing spacecraft that can deliver cargo and, later, astronauts to the International Space Station. RPK’s bid eventually collapses in financial scandal, though SpaceX goes on to create Dragon, the first privately-funded vehicle to visit the ISS in 2012.
