The shuttle's successors

In 2010 SpaceX became the first privately owned company to send a spacecraft into orbit and recover it, using an uncrewed Dragon capsule. They estimate Dragon can carry seven astronauts to the International Space Station (ISS) for $20m (£12.5m) a seat. Later this year, Dragon is scheduled to begin a series of 12 cargo missions to the ISS.

Garrett Reisman, SpaceX

Dragon

  • 2014 launch date
  • Falcon 9 launch vehicle
  • 7 total crew capacity
  • $75m Nasa funding so far*
  • Sea landings
    with parachutes

The Dragon spacecraft is receiving development grants from Nasa, as part of the commercial crew development programme. Dragon is launched on a Falcon 9 rocket, also built by SpaceX, unlike most of its competitors, which will initially use the Atlas 5. Although current operation calls for a water landing, SpaceX intends to develop a thruster system that would eventually allow Dragon to make a soft touch-down on land.
