Orion (Orion Multi-Purpose Crew Vehicle or Orion MPCV) is a partially reusable crewed spacecraft used in NASA 's Artemis program. The spacecraft consists of a Crew Module (CM) space capsule designed by Lockheed Martin and the European Service Module (ESM) manufactured by Airbus Defence and Space.

Orion is NASA’s new spacecraft, built to take humans farther into space than they’ve ever gone before. It will carry the crew to space, provide emergency abort capability, sustain the crew and provide a safe return to Earth.

The Orion spacecraft (more formally, the Orion Multi-Purpose Crew Vehicle) is NASA's vehicle of choice to take astronauts to the moon, a future lunar space station and potentially, on to Mars.

Orion, NASA’s newest spacecraft built for humans, is developed to be capable of sending astronauts to the Moon and is a key part of eventually sending them on to Mars. An uncrewed Orion will be tested on Artemis I and travel 40,000 miles past the Moon, farther than any spacecraft built for humans has gone before.
