NASA’s Artemis Human Landing Systems

The Human Landing System (HLS) is the mode of transportation that will take astronauts to the lunar surface in NASA's Artemis lunar exploration program. On early missions, the astronauts will live inside the pressurized crew cabin portion of the lander for up to a week. The HLS program, based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, is working closely with commercial partners to build innovative and technically advanced lunar landers, leveraging decades of human spaceflight experience and the speed of the commercial sector. In addition to the NextSTEP-2 Broad Agency Announcement Appendix H Option A contract that includes one uncrewed and one crewed demonstration mission to the lunar surface, the HLS program is taking steps to establish a regular cadence of crewed missions to the surface of the Moon. This paper will discuss the HLS program’s latest development activities.
