Solar and Planetary Research Grants

Astronomy and Astrophysics Research Grants (AAG), not under the SPG Program.Proposals that address planet formation within circumstellar disks are appropriate for this SPG Program; proposals that address star formation are better directed to the AAG Program and will not be considered by the SPG Program. Proposals submitted to one of these two programs, and deemed more appropriate for the other program, will be routed to the other program and considered during the next proposal submission season for that program. Potential proposers are cautioned that this could delay a proposal considered more appropriate to the AAG Program for up to a year. Proposals that are solely or predominantly for the acquisition, analysis, or interpretation of space-based data from NASA-supported missions will be returned without review.
