Amendment 51: D.15 Astrophysics Pioneers Final Text and Due Dates

ROSES-2021 Program element D.15 "Astrophysics Pioneers" solicits Astrophysics space and sub-orbital science investigations that are greater in cost, scope and capability than possible via the Astrophysics Research and Analysis program, but are smaller in cost than what is possible within the Astrophysics Explorers Mission of Opportunity (MO) program (e.g., PEA O of SALMON-3 for the 2019 opportunity). Investigations are solicited using platforms that include cubesats (including constellations), SmallSats, lunar surface hosted payloads via the Commercial Lunar Payloads Services program, major balloon missions, and International Space Station (ISS)-attached payloads. 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-2021 Amendment 51 releases final text and due dates for D.15 Pioneers. Mandatory Notices of Intent are due January 27, 2022, and proposals are due March 17, 2022.

On or about December 3, 2021, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2021" (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at
