NASA issued a draft Broad Agency Announcement under NextSTEP‑3, Appendix A, on June 29, 2026, to advance concepts that accelerate the technological readiness of critical systems for lunar surface and cislunar architecture.

This solicitation seeks to close key technology gaps and mature capabilities in vertical solar arrays, ISRU oxygen production systems, Stirling radioisotope generators, in‑space manufacturing, and advanced nanomaterials production.

It focuses on identifying technology areas that require further risk reduction and ground‑based testing to mature competing solutions to Technology Readiness Level (TRL) 5–6. Funded efforts will advance the technology objectives of NASA’s Moon Base by demonstrating critical systems and accelerating the development of transformative capabilities needed for near‑term mission success.
