The Exploration Mission 2 or EM-2 is scheduled to be the first crewed mission of NASA's Orion on the Space Launch System. The mission is to restart manned exploration of the Solar System. NASA is aiming to launch between 2021 and 2023, with a crew to perform a practice flyby of a captured asteroid in lunar orbit. This mission is expected to be the first time Americans will have left low Earth orbit since Apollo 17 in December 1972.
EM-2 is a single-launch mission of a Space Launch System Block IB with an Exploration Upper Stage, lunar Block 1 Orion Multi-Purpose Crew Vehicle (MPCV), and a payload insertion of 50.7 t. It is to be an 8 day mission with a crew of four astronauts, sent on a free return trajectory around the Moon.
