ROSES-25 Amendment 40: Exoplanets Research Program Step-2 Due Date Deferred to February 2, 2026

The Exoplanets Research Program (XRP), element F.3 of ROSES-25, solicits basic research proposals to conduct scientific investigations that significantly improve our understanding of exoplanets and exoplanet formation.

This program element is cross-divisional and jointly managed by three of the Divisions within NASA’s Science Mission Directorate: Astrophysics, Planetary Science, and Heliophysics.

Proposed investigations that combine multiple scientific disciplines, or that cross traditional Divisional science boundaries (for example, by including topics or analysis techniques from Heliophysics and Planetary Sciences), are highly encouraged.

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/.

Questions concerning F.3 XRP may be directed to the XRP program officers at [email protected].
