Artemis II is a ten-day U.S. spaceflight to send four astronauts on a flyby around the Moon and back to Earth. Launched from Kennedy Space Center on April 1, 2026, the mission is crewed by NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen. It is the second flight of the Space Launch System (SLS), the first crewed mission of the Orion spacecraft, and the first crewed mission beyond low Earth orbit since Apollo 17 in December 1972.
