The shuttle's successors

At first sight the Dream Chaser looks like a smaller version of the Space Shuttle, the vehicle it is designed to replace. In fact its origins can be traced back to the designs for Nasa's unfinished HL-20, a winged craft that was to serve as the lifeboat for the International Space Station.

Dream Chaser

  • 2015 launch date
  • Atlas V launch vehicle
  • 7 total crew capacity
  • $100m Nasa funding so far*
  • Runway landings

Like the shuttle, Dream Chaser's primary mission is to carry crew and cargo into low-Earth orbit and the International Space Station. Its developer, the Sierra Nevada Corporation, says the re-usable craft will be able to land on conventional runways.
