ROSES-25 Amendment 38: D.5 Astrophysics Pioneers Updates and Due Dates Delayed

14 January 2026

D.5 Astrophysics Pioneers solicits proposals for Astrophysics space and sub-orbital science investigations that are greater in cost, scope, and capability than possible within the Astrophysics Research and Analysis suborbital and CubeSat program but are smaller in cost than what is possible within the Astrophysics Explorers Mission of Opportunity (MO) program (e.g., PEA Q of SALMON-3 for the 2021 opportunity). Investigations are solicited using platforms that include CubeSats (including constellations), other SmallSats, and major balloon missions.Technology development and maturation within the proposed project is allowed, but the primary review criterion for selection is the merit of the proposed science investigation

ROSES-2025 Amendment 38 delays the due dates for this program and makes three small changes to Section 5.3. Mandatory Notices of intent are now due February 11, 2026, and proposals are now due April 2, 2026. New text is in bold and deleted text is struck through.

On or about January 14, 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/

Programmatic questions concerning D.5 Astrophysics Pioneers may be directed to Pablo Saz Parkinson at pablo.sazparkinson@nasa.gov.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
