Solar System Observations (SSO) supports primarily Earth-based observations, including ground-, airborne- and space-based astronomical observations, of bodies in our Solar System. With ROSES-2022, SSO started soliciting proposals for analysis of archival data acquired with Earth-based observatories. This program seeks to understand the physical, chemical, and dynamical processes that shape the atmospheres, exospheres, surfaces, interiors, and motions of Solar System objects. Proposals are solicited for new observations over the entire range of wavelengths, from X-ray to radio, that contribute to the understanding of the nature and evolution of the Solar System and its individual constituents.
This program element does not have a proposal due date. Proposals may be submitted at any time, pending certain eligibility timing issues related to resubmissions and duplicate proposal avoidance (see the program element text and appropriate Division Overview appendix (e.g., Appendix A.1, B.1, C.1, etc.)). The date shown above of 3/29/2024 is the last day that proposals may be submitted.
