What's Happening?
NASA is preparing to release a solicitation for industry-led architecture concept development and refinement studies under the Next Space Technologies for Exploration Partnerships-3 (NextSTEP-3) initiative. This effort aims to address gaps in the Moon
to Mars Architecture, which outlines the capabilities needed for long-term human-led scientific discovery in deep space. The solicitation, titled NextSTEP-3 Appendix B: Moon to Mars Architectural Studies, is expected to be released at the beginning of 2026. It will invite proposals focusing on infrastructure, transportation, habitation, and planetary science capabilities. NASA plans to issue several calls per year for proposal submissions, with the first directed-topic study calls focusing on lunar and Mars mission concepts. These calls will include research into integrated surface power infrastructure and Mars crew transportation concept development.
Why It's Important?
The Moon to Mars Architecture is a critical component of NASA's long-term strategy for human exploration of deep space. By seeking industry participation, NASA aims to leverage external expertise and innovation to address key challenges in space exploration. This initiative could significantly advance the development of technologies and systems necessary for sustainable human presence on the Moon and Mars. The collaboration with industry partners is expected to accelerate the pace of technological advancements, reduce risks, and enhance the overall feasibility of future missions. Successful implementation of this architecture could position the U.S. as a leader in space exploration, with potential economic and scientific benefits.
What's Next?
NASA anticipates issuing the first directed-topic study calls in early 2026, focusing on lunar and Mars mission concepts. These calls will include research into integrated surface power infrastructure and Mars crew transportation. The agency will continue to refine its acquisition strategy to accommodate both directed-topic and open-topic calls, allowing for a broad range of innovative solutions. As proposals are submitted and evaluated, NASA will work closely with selected industry partners to develop and implement the necessary technologies and systems. The outcomes of these studies will inform future mission planning and execution, paving the way for more ambitious exploration goals.
