(NextSTEP-3). NASA plans to release this solicitation — NextSTEP-3 Appendix B: Moon to Mars Architectural Studies — near the beginning of calendar year 2026. For full details, consult the links under the notice ID above.

NASA’s Moon to Mars Architecture defines capabilities needed for long-term, human-led scientific discovery in deep space. The agency’s architecture approach distills agency-developed objectives into capabilities and elements that support exploration and science goals. NASA continuously evolves that blueprint for crewed exploration, setting humanity on a path to the Moon, Mars, and beyond by collaborating with experts across industry, academia, and the international community.

This proposed solicitation seeks partner participation on a recurring basis, targeting several calls per year for proposal submissions. The proposals should focus on topics addressing infrastructure, transportation, habitation, concepts of operations, and planetary science capabilities identified in the latest revision of the

. The solicitation establishes a flexible acquisition strategy that accommodates both directed-topic calls on specific areas of government interest, as well as open topic calls.

NASA anticipates the first Appendix B directed-topic study calls will focus on lunar and Mars mission concepts. NASA intends to issue a directed call for research into an integrated surface power infrastructure (or power grid) that can evolve to support increasingly ambitious lunar missions. (Note: this call excludes proposals addressing the

but may include all technology solutions including alternate fission, solar hybrid, or other power grid approaches.)

Concurrently, NASA will issue a directed call for Mars crew transportation concept development, trade studies, and identification of risk reduction activities. This call would include in-space transportation, Mars surface access, and Mars ascent options for crew and cargo.
