Artemis 1 (known as Exploration Mission-1 or EM-1 before the introduction of the Artemis program) is the second planned flight of the uncrewed Orion Multi-Purpose Crew Vehicle to be launched on the first flight of the Space Launch System. The launch is planned from Launch Complex 39B at the Kennedy Space Center no earlier than November 2020. The Orion spacecraft will spend approximately 3 weeks in space, including 6 days in a retrograde orbit around the Moon. It is planned to be followed by Artemis 2 between 2022 and 2023.
The Block 1 version of the SLS rocket 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. Artemis 1 mission is intended to demonstrate the integrated spacecraft systems prior to a crewed flight, and in addition, test a high speed reentry (11 km/s or 6.8 mi/s) on Orion’s thermal protection system.
