All this is in preparation for the Artemis II mission, scheduled for launch in Sept 2025.
The spacecraft, with 4 astronauts, will perform a flyby of the Moon and return to Earth using a free-return trajectory from the Moon. Unlike the similar Apollo 8 mission, the Orion spacecraft will not enter lunar orbit.
The mission will be the 1st to carry humans beyond low Earth orbit since Apollo 17 in 1972.
Artemis III will feature human landing on the moon.
