NASA officially expects Artemis III to launch no earlier than 2028. The mission was delayed from an initial target of September 2026 in January 2024 and further pushed back to 2027 in December 2024 before the final adjustment to 2028.
Artemis III aims to land two astronauts at the Moon's south polar region while up to four astronauts launch aboard Orion. Only two astronauts will descend to the surface aboard Starship HLS while the others remain aboard Orion during descent and ascent phases.
The total mission duration including flights will be about 30 days. This timeframe covers the journey from Earth to lunar orbit, the surface operations lasting approximately one week, and the return trip.
Artemis III aims to land two astronauts at the Moon's south polar region. The goal is to sample lunar water ice found in permanently shadowed craters within this specific area.
Delays occurred due to spacesuit readiness issues reported by an Office of Inspector General audit on the 10th of August 2021 and technical hurdles with SpaceX Starship HLS. Valve problems in the life support system and heat shield issues on Orion contributed to schedule slippage that pushed the launch date from 2025 to 2028.
