• NOTICE: Amended October 3, 2025. This amendment changes to "TBD" the Step-2 proposal due date for F.15 Artemis III Participating Scientist Program. The solicitation "close date" shown in NSPIRES is NOT a new proposal due date; that is merely an artefact of the NSPIRES system. When funding is reinstated, an amendment will be issued setting a new Step-2 proposal due date. We anticipate that proposers to programs that were set to TBD will be given back as many business days as the government was shut down.
• NOTICE: Corrected September 23, 2025. The contents of the Expertise and Resources Not Anonymized Documents in Table F.15-2 were corrected. New text is in bold and deleted text is struck through.
• NOTICE: Corrected September 19, 2025. References and citations are permitted after and outside the page-limited sections, see Tables F.15-1 and -2. New text is in bold and deleted text is struck through.
