During this time the crew will perform various checkouts of the spacecraft's life support systems as well as an in-space rendezvous and proximity operations demonstration using the spent Interim Cryogenic Propulsion Stage (ICPS) as a target. The Orion spacecraft will be sent to a high Earth orbit with a period of roughly 42 hours. The mission profile is a multi- trans-lunar injection (MTLI), or multiple departure burns, and includes a free-return trajectory from the Moon. The Artemis 2 mission plan is to send four astronauts in the first crewed Orion MPCV spacecraft into a lunar flyby for a maximum of 21 days using the Block 1 variant of the Space Launch System. The mission is also planned to be the first crewed launch from LC-39B since STS-116. Originally designated Exploration Mission-2 ( EM-2), the mission was intended to collect samples from a captured asteroid in lunar orbit by the now canceled robotic Asteroid Redirect Mission it was renamed after the introduction of the Artemis program.
Artemis 2 is planned to be the first crewed spacecraft to travel to the Moon, and beyond low Earth orbit, since Apollo 17 in 1972. The crewed Orion spacecraft will perform a lunar flyby and return to Earth. Artemis 2 (officially Artemis II) is the second scheduled mission of NASA's Artemis program and the first scheduled crewed mission of NASA's Orion spacecraft, currently planned to be launched by the Space Launch System (SLS) in November 2024.
