Artemis II is expected to take about 4 days to reach the Moon on its outbound trip, and the full mission is planned to last about 10 days. NASA’s current mission descriptions say the journey to lunar vicinity is around three to four days, with the spacecraft then looping around the Moon and returning to Earth.

Quick Scoop

  • Time to reach the Moon: about 4 days.
  • Whole mission duration: about 10 days.
  • Mission type: a lunar flyby , not a landing.

What that means

Artemis II is designed to send astronauts around the Moon and back on a free- return trajectory, so it is more like a long-distance test flight than a landing mission. NASA’s published mission overviews indicate the spacecraft will spend a few days traveling outward, then swing around the Moon, and then spend several more days coming home.
