Artemis II is planned as a roughly 10‑day mission that loops around the Moon and then returns to Earth, splashing down in the ocean.

Because the mission launched on 1 April 2026, that means “coming back” (re‑entry and splashdown) is expected about 10 days after launch, so approximately around 10–11 April 2026, assuming the flight stays on its nominal timeline and no in‑flight extensions or contingencies occur.

NASA’s official description notes that Artemis II is designed as a 10‑day flight to test the Space Launch System rocket and Orion spacecraft with a crew before later missions attempt an actual Moon landing.
