NASA has announced a new submission date for Step-2 proposals under the F.15 Artemis III Participating Scientist Program (A3PSP), giving researchers a fresh opportunity to join humanity’s next giant leap in lunar exploration. The updated deadline, set as November 25, 2025, comes after previous delays caused by a lapse in government funding. This reset ensures that scientists who submitted Step-1 proposals can continue to compete for a role in the Artemis III mission, contributing to cutting-edge lunar research.
Step-2 Proposal Deadline Reset
ROSES-2025 Amendment 21 officially resets the Step-2 proposal due date for the F.15 A3PSP. Initially marked as “TBD” due to funding gaps, NASA now confirms that Step-2 proposals must be submitted by November 25, 2025. Only researchers who submitted Step-1 proposals are eligible to advance to this next stage, maintaining the program’s focus on pre-vetted candidates. This step ensures continuity in NASA’s selection process for the Artemis III mission, which will return humans to the Moon and expand scientific understanding of lunar geology.
Accessing the Amendment
On or about November 18, 2025, Amendment 21 will be posted on the official NASA Research Opportunities homepage: https://solicitation.nasaprs.com/ROSES2025
. It will also appear on NASA’s SARA ROSES blog: https://science.nasa.gov/researchers/solicitations/roses-2025/
. These platforms provide the official guidelines and details for eligible scientists to prepare and submit their proposals.
Support and Contact Information
Scientists with questions regarding the F.15 A3PSP can reach out directly to program contacts Sarah Noble and Amanda Nahm via [email protected]
. Direct inquiries ensure participants receive accurate guidance for their submissions and can clarify any uncertainties about eligibility, proposal requirements, or the review process.
What Undercode Say:
The Artemis III Participating Scientist Program represents a critical avenue for the integration of scientific research into NASA’s lunar missions. By setting the Step-2 proposal deadline to November 25, 2025, NASA provides a structured timeline that aligns with the broader Artemis III mission schedule. This timeline allows sufficient preparation for the mission’s scientific payload and ensures that selected scientists have the necessary time to plan experiments that will yield meaningful lunar data.
The program is strategically limited to Step-1 proposal submitters, which reduces administrative burden while prioritizing candidates with demonstrated capability and readiness. This tiered approach enhances the quality of proposals, as Step-1 evaluation already filters for feasibility, scientific relevance, and alignment with Artemis III objectives. For researchers, this is not just a submission; it is an opportunity to influence lunar exploration in tangible ways.
The reset also reflects NASA’s adaptability in response to external disruptions such as funding lapses. Maintaining continuity despite delays demonstrates organizational resilience and commitment to scientific goals. By providing a clear and definitive due date, NASA reinforces confidence in the program among the research community, ensuring active participation and minimizing uncertainty.
Moreover, the inclusion of direct support via program contacts underscores NASA’s effort to guide participants effectively, reducing proposal errors and increasing the likelihood of successful submissions. The accessibility of amendment details through official portals ensures transparency and allows all candidates to prepare thoroughly.
Scientifically, Artemis III will offer unprecedented insights into the Moon’s geology, resources, and environmental conditions. Participating scientists stand to gain unique data sets that can fuel decades of research, while NASA benefits from collaborative expertise that enhances mission value. This partnership between human exploration and scientific inquiry exemplifies the modern approach to space research, emphasizing cross-disciplinary collaboration and tangible outcomes.
Ultimately, the Step-2 proposal reset is more than an administrative update—it signals NASA’s intent to keep Artemis III scientifically robust. Researchers should view this as a call to refine their proposals with precision, creativity, and alignment with lunar exploration priorities. Those selected will not only contribute to historic missions but also help shape humanity’s understanding of Earth’s nearest celestial neighbor.
Fact Checker Results:
✅ Deadline for Step-2 proposals confirmed as November 25, 2025
