ROSES-25 Opportunity: Astrophysics Theory Program

9 November 2026

Proposals Due 3 February 2027

The ROSES-25 D.10 Astrophysics Theory Program (ATP) supports efforts to develop the basic theory for NASA's space astrophysics programs. The proposed work submitted for this program must both:

  • Be directly relevant to NASA space astrophysics goals by facilitating the interpretation of data from space astrophysics missions or by leading to predictions that can be tested with space astrophysics observations; and
  • Consist predominantly of theoretical astrophysics studies or the development of theoretical astrophysics models.

ATP proposals satisfying both of the above requirements may involve development of data analysis methods for astrophysics missions and may incidentally include actual data analysis as a test of the theory or the method.

ROSES-2025 Amendment 81 releases D.10 ATP as a new opportunity in ROSES-25. Neither NOIs nor Step-1 Proposals are requested. Proposals are due 3 February 2027.

Please direct questions concerning D.10 ATP to Sanaz Vahidinia at HQ-ATP@mail.nasa.gov.

This cropped horizontal image has layers of semi-opaque rusty red colored gas and dust that starts at the bottom right and goes toward the top left. There are three prominent pillars rising toward the top left. The left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines.
