Orion is NASA’s next exploration spacecraft to send astronauts farther into space than ever before, beyond the Moon to asteroids and even Mars.

ESA has contracted and is overseeing the development of the European Service Module, the part of the Orion spacecraft that provides air, electricity and propulsion. Much like a train engine pulls passenger carriages and supplies power, the European Service Module will power the Orion crew module to its destination and back to Earth.
