NASA released a solicitation under Appendix E of the second Next Space Technologies for Exploration Partnerships (NextSTEP-2) Broad Agency Announcement (BAA) to seek proposals from industry in support of design analysis, technology maturation, system development and integration, and spaceflight demonstrations for a human lunar landing system. Proposals were received March 25, 2019.

Appendix E will be a six-month risk reduction effort including studies and prototype development. Following the March 26 announcement by Vice President Pence that charged NASA to send humans to the lunar South Pole by 2024, NASA assessed options to expedite the work. Appendix E will continue, and will be used to guide NASA’s HLS requirements, formulation and planning. The HLS development and crewed flight demonstration will be competed under a new, open solicitation, NextSTEP Appendix H, Integrated Human Landing System

Feb. 14 2019 Industry Forum

NASA hosted a Human Landing System Industry Forum on February 14, 2019 in Washington, DC at the NASA Headquarters James E. Webb Auditorium. NASA Administrator James Bridenstine and senior NASA managers summarized the agency’s plans to partner with industry to develop a human lunar landing system. NASA provided a status of the current lunar architecture and an overview of the NextSTEP-2 Appendix E BAA, and the event included an open Question & Answer session for industry participants.
