Artemis II target launch date and current program status
Artemis II is the first crewed flight test of NASA’s Orion spacecraft and SLS rocket, planned to orbit the Moon and return to Earth. As of mid-2026, Artemis II remains in late production and testing; NASA has not set a firm launch date, following earlier schedule slips. The mission remains critical to Artemis III and sustainable lunar operations, with official updates expected via NASA channels.
What is Artemis II and why it matters
Artemis II will send astronauts around the Moon and safely return them, proving core Orion and SLS systems, operations, and human-rating for future missions. It is a foundational step before Artemis III’s lunar landing and long-term surface activities. The flight will demonstrate deep space navigation, life support, and emergency procedures, providing high-value data for crewed lunar exploration.
Latest official status as of 2025–2026
NASA publishes Artemis II status in quarterly reports, mission updates, and Artemis campaign summaries. No firm launch window has been announced after delays affecting SLS and Orion final tests. The agency emphasizes readiness over rigid calendars, prioritizing crew safety and system verification. Partners including ESA (European Service Module) and contractors continue integration and testing work.

Recent development timeline (context, not a prediction)
Artemis II has moved from planning to hardware completion: Orion capsules underwent environmental testing, SLS stages were assembled and processed at Kennedy Space Center, and mission simulations have been conducted. Formal crew training and dress rehearsals preceded earlier planned launch windows. Subsequent reviews revealed additional work, extending timelines. Official milestone reviews now govern any future date announcements.
What to expect before and after launch
Before Artemis II, NASA will complete integrated testing, review all certification results, and provide public updates through official Artemis channels. After launch, the mission will execute a multi-day outbound transit, lunar flyby, and return trajectory using Earth’s atmosphere for a skip-like entry profile. Recovery operations in the Pacific will conclude the flight test, informing Artemis III and beyond.

Common questions about Artemis II timing
Will Artemis II launch in 2026? NASA has not confirmed 2026. Has Artemis II been canceled? No; the mission remains active. When will we know a firm date? After full review gates and certification reviews, with public announcements via NASA channels. Is Artemis II dependent on Artemis III? Artemis II is a prerequisite proving crewed flight capability ahead of landing missions.
Bottom line on when Artemis II will fly
Artemis II does not have an announced launch date as of 2026, following earlier schedule slips. The mission is in late production and testing, with official status updates provided by NASA. Crewed lunar flyby timelines will be confirmed only after rigorous review and certification, so treat any firm date as speculative until NASA declares readiness.
