NASA ROSES-25 Amendment 39: Rolling Submissions Extended Through August

Historically the new omnibus ROSES solicitation was released in February but proposals to the programs from the prior year’s ROSES that were rolling submissions (no due date) could be submitted until the end of March. This overlap period allowed those who had a proposal in work to submit it rather than having to start again. This year we anticipate that ROSES-26 will be released in July so the close date for ROSES-25 has been extended to the end of August.

ROSES-2025 Amendment 39 extends due dates for three program elements: 1) It extends the last date for submission to C.2 Solar System Science to August 1, 2026, see footnote [4] in Tables 2 and 3 of ROSES-25. 2) it extends the last date for proposals to A.4 Rapid Response and Novel Research in Earth Science and A.10 INNOVATE to August 31, 2026, see footnote [3] in Tables 2 and 3 of ROSES-25. However, once ROSES-26 is released (in July 2026), proposers are strongly encouraged to create new proposals vs. the new ROSES.

Moreover, this amendment also makes other changes to the program elements, so please review the text. For example, the expected budget and number of new awards in Section 4 of C.2 Solar System Science have been increased.

On or about January 22, 2026, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2025” (NNH25ZDA001N) will be posted on the NASA research opportunity homepage at https://solicitation.nasaprs.com/ROSES2025 and will appear on SARA’s ROSES blog at: https://science.nasa.gov/researchers/solicitations/roses-2025/
