The Artemis Program is a NASA-led multinational lunar exploration program that will reestablish human presence on the Moon since Apollo 17 in 1972. It was formally established in 2017 as a replacement/successor to the Space Shuttle and Constellation programs, aiming to make the first crewed landing on the Moon in the 21st century by 2025


  • This addon only includes the Orion spacecraft. Other components (like CAPSTONE, the CLPS landers, Starship HLS, etc.) will be released as separate addons
  • The maiden flight of Orion is a separate addon here: Exploration Flight Test-1
  • The Artemis 2 mission is not yet included as there has no sufficient public information to accurately simulate it on Celestia
  • For Artemis 3 and beyond, the Lunar Gateway addon must be installed first
