From Wikipedia, the free encyclopedia
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. Set to launch in 2017 from Launch Complex 39B at the Kennedy Space Center, the Orion spacecraft would perform a circumlunar trajectory during the seven day mission.[3][5] 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 a Interim Cryogenic Propulsion Stage.[5] 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]
