Amendment 22: C.8 Yearly Opportunities for Research in Planetary Defense Step-2 Proposal Due Date Reset to December 3, 2025

ROSES-2025 Amendment 22 resets the step-2 proposal due date for C.8 Yearly Opportunities for Research in Planetary Defense (YORPD), which was previously set to TBD because of the lapse in government funding. The new Step-2 proposal due date for this program element is December 3, 2025. Only those who previously submitted a Step-1 proposal can submit a Step-2 proposal.

On or about November 18, 2025, 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
