• NOTICE: Amended July 17, 2025. The Step-1 due date has been deferred to November 25, 2025.
• NOTICE: Amended July 15, 2025. ROSES-25 Amendment 1 announces restrictions on funding of interagency awards from most proposal opportunities in ROSES-25: Appendix A (Earth Science) of ROSES-25 already had a prohibition on funding to government agencies other than NASA. Appendix C, (Planetary Science) has also adopted this prohibition. Appendix B (Heliophysics), Appendix D (Astrophysics), and F.3 The Exoplanet Research Program have not applied an outright prohibition, but require that any proposer planning on funding for or through government agencies other than NASA must seek approval from the point of contact for the program element to which they are planning to propose.
• D.1 The Astrophysics Research Program Overview notes that approvals for interagency awards for less than $100k per year are unlikely to be granted, regardless of whether the Federal Agency is the submitting institution or a Co-I institution. For more information, see the research program overviews (A.1 -- D.1 & F.1) and Sections I(d)i and III(a) of the ROSES-25 Summary of Solicitation. New text is in bold and, where applicable, deleted text is struck through.
• The description of the specific proposal opportunity on this page is contained in the document 'F.3 Exoplanets Research'. The document 'F.1 Cross Division Research Overview' describes research activities within the NASA science division that is managing the specific proposal opportunity on this page and may impose requirements upon proposals submitted to this program element. The document 'Summary of Solicitation' describes the common requirements for all ROSES-2025 proposal opportunities. The document 'Table 1' contains the proposal check list from the Summary of Solicitation. The documents 'Table 2' and 'Table 3' contain the list of all proposal opportunities and their due dates, sorted by (full or Step-2) proposal due date or appendix number, respectively. All of these documents are kept up to date and incorporate amendments, clarifications, and corrections in a clearly identifiable manner.
