NASA, ESA Agree on New Orion Service Module video




This animation shows NASA's Orion spacecraft as it will appear on its Exploration Mission-1 in 2017, complete with a service module to be provided by the European Space Agency.

After Orion blasts off atop a Space Launch System rocket, the ESA-provided service module will fuel and propel the capsule on its journey through space. Exploration Mission-1 in 2017 will be the first mission to incorporate both the Orion vehicle and NASA's new Space Launch System. It will follow the upcoming Exploration Flight Test-1 in 2014, in which an uncrewed Orion will launch atop a Delta IV Heavy rocket and fly 3,600 miles above Earth's surface, farther than a human spacecraft has gone in 40 years.
