Orion MPCV (Multi-Purpose Crew Vehicle) is planned manned spacecraft for missions to the moon, asteroids and eventually to Mars.
MPCV ia a capsule design, which inherits its shape from the Apollo capsule, but is otherwise a completly new construction. It was to launched on a Ares-1 launcher derived from Space Shuttle technology. In contrast to Apollo, landing will be on land, assisted by air-bags or retro-rockets.
After the Constellation was cancelled, the Orion CEV capsule was renamed Orion Multi-Purpose Crew Vehicle (MPCV). It will serve as a vehicle for lunar and interplanetary missions. The LEO missions to ISS will instead be flown on commercial vehicles.
In late 2012 ESA joined the project and will provide a service module for Orion based on the ATV service module. The OME main engine for the first three missions are Aerojet AJ10-190 (OMS) engines left over from the Shuttle. Later missions will feature a different engine, possibly with green propellants.
The first Orion MPCV capsule will be launched in 2020 on a SLS (Block 1) rocket. The second will follow in 202ies on an improved SLS (Block 1B) EUS rocket on missions to lunar orbit. The first one will be unmanned, the second one will carry four astronauts.
Later, Orion MPCV will perform lunar and interplanetary missions.
