Notice of Intent Due Date: February 11, 2026
Proposal Due Date: April 02, 2026
This program element solicits proposals for “Pioneers”, Astrophysics space and suborbital science investigations that are greater in cost, scope, and capability than what was possible within the Astrophysics Research and Analysis (APRA) 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 Small Sats, 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.
All proposed investigations must be responsive to NASA’s science goals in Astrophysics, as described in the FY 21-22 Update to “Science 2020-2024: A Vision for Scientific Excellence” and the 2022 NASA Strategic Plan, both of which may be found at http://science.nasa.gov/about-us/science-strategy/.
