Artemis: An Overview of NASA's Activities to Return Humans to the Moon

NASA is well underway in its plans to return humans to the Moon and build long-term infrastructure both in orbit and on the surface. Following the Artemis I and Artemis II flight tests, NASA will begin crewed landings and regular missions to the Moon. Artemis will return value to the American public and the global community, enable groundbreaking scientific discovery, and prepare NASA and its partners for exploration of the solar system. Work on the initial Human Landing System (HLS), procurement activities for future HLS, and work on the initial modules of the lunar-orbiting Gateway are underway. International partnerships are playing a critical role in the planning, development, and execution of these missions. As of December 2021, three international partners have entered agreements to contribute to the Gateway and 14 nations have signed the Artemis accords. A new spacesuit acquisition strategy will stimulate economic growth and meet the growing needs of NASA and emerging customers. Requirements development is underway for an unpressurized lunar surface rover and plans for a pressurized rover, foundation surface habitat, and the Artemis Base Camp are in work. This paper will provide an update on the HLS demonstration missions and the procurement status for HLS services; a comprehensive look at the Gateway's components and related statuses; a summary of planned surface systems; and an outline of the strategies NASA will use to successfully implement these plans, preparing for humanity's next giant leap: Mars.
