NASA has confirmed that February 6 through February 11, 2026 marks the opening launch window for Artemis II, the first human mission since the Apollo era.
If launch conditions are not met during the February window, NASA has established backup opportunities in March and April, allowing flexibility as final testing, reviews, and weather assessments continue.

Artemis II will send four astronauts aboard the Orion spacecraft on a multi day lunar flyby trajectory. While no landing is planned, the mission will carry humans beyond low Earth orbit for the first time since Apollo 17 in 1972.
The flight is designed to rigorously test life support systems, deep space navigation, communications, and spacecraft performance in the lunar environment before NASA attempts surface missions later in the decade.

Unlike uncrewed test missions, Artemis II represents the transition to operational human deep space flight. The mission will evaluate how Orion and its crew perform during extended operations tens of thousands of kilometers from Earth, including high speed lunar return conditions.
NASA considers Artemis II a critical prerequisite for Artemis program goals that include a sustained human presence on and around the Moon.

Launch windows are determined by orbital mechanics, recovery constraints, lighting conditions, and tracking coverage. The February 6–11 window represents the first alignment that satisfies all mission requirements, with March and April reserved as planned alternatives.
In the coming weeks, NASA teams at Kennedy Space Center will complete final integrated testing, countdown rehearsals, and readiness reviews ahead of a formal launch decision.

Artemis II marks the moment the Artemis program moves from preparation to execution with astronauts aboard. Once Orion launches with its crew, human spaceflight will officially return beyond Earth orbit, opening the next chapter of lunar exploration and setting the foundation for future surface missions.
The opening of the launch window signals that the return toward the Moon is no longer theoretical. It is scheduled.
