The CST-100 is Boeing's entrant into the race to replace the shuttle as part of Nasa's Commercial Crew Development programme.

The spacecraft is slightly wider than the Apollo capsule, with a base about 15ft across (4.5m). It will be re-usable for up to 10 missions and will be launched from either an Atlas V, Delta IV or a Falcon 9 rocket. The spacecraft will land using parachutes.
