The Orion Multi-Purpose Crew Vehicle will be America’s next manned spacecraft. The capsule has been in development since 2005. In 2013, NASA announced that the European Space Agency will build Orion’s Service Module using hardware that was developed for the Automated Transfer Vehicle (ATV), a cargo ship built to service the International Space Station.

Orion’s Crew Module houses four astronauts for deep-space missions lasting up to three weeks.

The Service Module, built by the European Space Agency carries rocket engines for propulsion, large solar panels for generating electrical power and oxygen for the astronauts to breathe.

The Spacecraft Adapter is a set of panels for protecting the Service Module during the ascent through the Earth’s atmosphere.

An Instrument Unit contains guidance and control electronics for the booster rocket.

Orion will be launched on the Space Launch System booster. The vehicle features components evolved from those used in the Space Shuttle’s booster system. A central core stage has five liquid-fueled rocket engines. Strapped at the sides are large solid fuel boosters similar to the shuttle’s SRB boosters, but containing more fuel.

Orion’s first uncrewed test flight took place on Dec. 5, 2014. Orion was scheduled to make another test flight during the debut launch of the SLS rocket, with a crewed flight to follow in the 2020s, but that schedule is under consideration.
