Mission Brief

Artemis II is the first crewed mission as part of the Artemis program. Artemis II will send a crew of 4 - 3 Americans and 1 Canadian around the moon and return them back to Earth. The mission will test the core systems of NASA's Orion spacecraft including the critical life support system, among other systems which could not be tested during Artemis I due to the lack of crew onboard.
