Artemis II is currently expected to launch in early February 2026, with NASA targeting a window that opens around 5–6 February 2026 rather than a single fixed date, and officially describing the mission as launching “no earlier than” that time and “no later than April 2026.”

Quick Scoop: Artemis II Launch Timing

  • The earliest launch window for Artemis II opens in early February 2026, with NASA planning for “no earlier than” about 5–6 February 2026 for liftoff.
  • NASA also lists the mission more broadly as scheduled no later than April 2026 , giving flexibility for any final tests, weather, or technical issues.
  • Within that February window, specific days such as 6–11 February 2026 are identified as viable launch opportunities depending on orbital constraints and vehicle readiness.

Why There Isn’t One Exact Day Yet

  • Lunar missions like Artemis II must launch within narrow windows tied to the Moon’s position, lighting conditions, and the planned trajectory, so agencies quote ranges rather than a single firm date until very close to launch.
  • Final timing will depend on technical readiness checks, rollout and rehearsal milestones at Kennedy Space Center, and weather , which is why NASA continues to use “no earlier than” language for the mission.

In practical terms, if you’re tracking when does Artemis 2 launch , plan around the early-February 2026 window, while expecting that the exact day and hour could still shift as NASA completes final preparations.
