Exploration Mission 1 or EM-1 (previously known as Space Launch System 1 or SLS-1) is the first planned flight of the Space Launch System and the second uncrewed test flight of the Orion Multi-Purpose Crew Vehicle. As of April 2012 , the launch was projected to occur on December 17, 2017 from Launch Complex 39B at the Kennedy Space Center, and the Orion spacecraft would perform a circumlunar trajectory during the seven day mission. [3 ] It will be followed by [5 ] Exploration Mission 2.
Overview [ edit ]
The Block 1 version of SLS used on this mission will consist of two
five-segment Solid Rocket Boosters, four RS-25D engines built for the Space Shuttle program and an Interim Cryogenic Propulsion Stage. EM-1 is intended to demonstrate the integrated spacecraft systems prior to a crewed flight and demonstrate a high speed reentry (11 km/s) on Orion's thermal protection system. [5 ] [5 ]
On January 16, 2013, NASA announced that the European Space Agency would build Orion's service module based on its Automated Transfer Vehicle, so the flight could also be regarded as a test of ESA hardware as well as American.
