NASA to Launch 'NextSTEP-3 Appendix B' Solicitation for Commercial Moon Base Demonstrations

NASA’s Exploration Systems Development Mission Directorate is preparing to issue a new call for commercial innovation aimed at establishing a permanent human presence on the Moon. Under the Next Space Technologies for Exploration Partnerships-3 (NextSTEP-3) Omnibus Broad Agency Announcement, the agency will soon release "Appendix B: Moon Base Demonstrations." This forthcoming solicitation invites private sector partners to propose industry-led demonstrations, risk-reduction concepts, and specialized technical activities designed to support the infrastructure of a long-term lunar base.

The initiative represents a crucial step in NASA's Artemis campaign, which aims to transition from initial human landings to sustained, year-round scientific and exploratory operations on the lunar surface. Unlike the Apollo missions of the 20th century, the modern lunar architecture relies heavily on commercial collaboration to develop critical technologies, such as surface power generation, waste management, localized resource extraction (in-situ resource utilization), and habitable structures. By leveraging the NextSTEP public-private partnership model—which has previously yielded advancements in lunar landers and deep-space habitats—NASA seeks to share both the financial costs and the technological breakthroughs required for deep-space survival.

"Establishing an enduring presence on the lunar surface requires us to think beyond transport and focus on daily survivability and operational efficiency," said a senior NASA exploration systems official. "Through Appendix B, we are opening the door for commercial partners to validate technologies that will mitigate risks and lay the groundwork for a thriving lunar economy." Key areas of interest in the upcoming solicitation are expected to include advanced thermal control systems, dust mitigation technologies, and autonomous construction techniques capable of withstanding the harsh lunar environment.

While the official solicitation is currently marked as "Coming Soon," industry stakeholders are already preparing proposals to align with NASA’s timeline for Artemis surface operations. The insights gained from these Moon base demonstrations are not only vital for sustaining life on the Moon but will also serve as a blueprint for eventual crewed missions to Mars. The formal Request for Proposals (RFP) is anticipated to be published on the federal government's acquisition portal in the coming weeks, signaling a competitive new phase in the commercial space race.
