Artemis II is expected to take about 10 days total, according to NASA and recent mission coverage. The journey to the Moon’s vicinity is about 3 days each way , with the full mission planned around that overall 10-day window.

Quick scoop

If you mean the whole mission , think about 10 days.

If you mean the trip to the Moon itself , the outbound leg is roughly 3 days , followed by time in lunar flyby operations before the return trip.

Why it matters

Artemis II is a crewed test flight, so the timeline is built around checking systems, flying a lunar free-return path, and bringing the astronauts home safely rather than landing on the Moon.
