Astrophysics Science SmallSat Studies (ROSES 2019)

Funding Agency:
National Aeronautics and Space Administration

This program element solicits proposals for six-month studies of spaceflight mission concepts that can be accomplished for low cost using small spacecraft in standard form factors, including CubeSats, CubeSat constellations, and secondary (RideShare) payloads launched as Expendable Launch Vehicle Secondary Payload Adapter (ESPA) and ESPA-grande-ring compatible spacecraft. All proposed investigations must be responsive to the science goals of the Astrophysics Division, as described in the 2014 NASA Science Mission Directorate Science Plan and the NASA 2018 Strategic Plan1. All proposed investigations must be more capable than the suborbital-class CubeSat missions that are solicited within the Astrophysics Research and Analysis (APRA) program (D.3 of ROSES-2018).

The Astrophysics Science SmallSat Studies (AS3) program is intended to capitalize on the creativity in the astrophysics science community to envision science enabled by smaller and significantly lower cost missions. NASA expects to make awards for mission concept studies that will span the breadth of possible science investigations enabled by CubeSat/SmallSat technologies and available secondary launch opportunities. Mission design assistance, if required, for these mission concepts will be offered by NASA during the six-month studies (see Section 3.1). If such assistance is proposed, the proposal must include its cost within the submitted budget. NASA solicited missions of this class in the recent 2019 Astrophysics Explorers Missions of Opportunity solicitation and plans to do so at each future Astrophysics Explorers solicitation.

NASA recognizes and supports the benefits of having diverse and inclusive scientific, engineering, and technology communities and fully expects that such values will be reflected in the composition of all proposal teams as well as peer review panels (science, engineering, and technology), science definition teams, and mission and instrument teams.
