NextSTEP-3 Appendix B: Moon Base Demonstrations

1. Introduction and Background

In December 2025, a national space policy was signed into place that emphasized America's leadership in space, including returning to the Moon, building a permanent base, investing in new technologies, and advancing lunar and orbital economies for future scientific missions. NASA’s Moon Base, located in the lunar South Pole region, will serve as the premier proving ground for deep space exploration, empowering scientific discovery and the development of advanced space technologies.
To accelerate phased implementation of Moon Base, NASA seeks to bridge the gap between technology development and mission operations, targeting concepts at technology readiness level (TRL) 6 and beyond. Industry partners play a critical role in addressing architectural gaps and risk reduction buy-down that create the knowledge foundation NASA needs to make informed programmatic decisions and strengthen its ability to achieve strategic exploration goals efficiently and effectively. To that end, NASA's Human Spaceflight Mission Directorate (HSMD) is actively embracing innovative ideas from industry partners through this Appendix B: Moon Base Demonstrations under the NextSTEP-3 Omnibus Broad Agency Announcement (BAA) that calls for industry-led demonstrations and special topic activities.

2. Acquisition Objective

2.1. Overview

The purpose of this solicitation is to acquire prototype demonstrations and special topic efforts that address critical architecture gaps identified for the lunar Moon Base. Awards will focus on the integration, demonstration, and maturation of concepts that have progressed beyond early component technology development.
The Government is seeking innovative solutions to advance lunar mission capabilities in key topic areas: infrastructure (including power and communication & position, navigation and timing (C&PNT)), transportation, mobility, habitation, autonomy & robotics, lunar and mission science, and mission Concept of Operations (CONOPS).
