Solar System Observations (SSO)
The ROSES 2023 Solar System Observations (SSO)   Appendix C.6

NOTICE: This program element now accepts proposals seeking to conduct analysis of archival data resulting from Earth-based observations of planetary bodies in our Solar System.
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 C.6, Section 4 for further information.
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.
Proposals must indicate how their proposed objectives advance scientific knowledge and the NASA Planetary Science strategic objectives. Those objectives are discussed in more detail in the NASA Science Plan .
Investigations involving near-Earth objects (NEOs) should be proposed to C.21 the Yearly Opportunities for Research in Planetary Defense (YORPD) program element.
Refer to ROSES program element C.1, Section 4, for a detailed list of the data and astromaterials resources, and facilities available to proposers to this program element, and how to use them.
Mission data are available from the Planetary Data System (PDS).

Data available from The Planetary Plasma Interactions (PPI) Node

Other Data Within PDS
The following Discipline Nodes have additional information:
Atmospheres Node
Cartography and Imaging Sciences Node
Ring-Moon Systems Node
Small Bodies Node
Geosciences Node
Ancillary data (SPICE files) can be obtained from the NAIF Node

Proposals to this program element may be submitted at any time without any preliminary statement such as a Notice of Intent or Step-1 proposal. See Section 2.4 of C.1 of the Planetary Science Research Program Overview and for further information.
The standard rule for use of existing mission data has been that unless otherwise specified, spacecraft mission data to be used in proposed work must be available in the Planetary Data System (PDS), or an equivalent, publicly accessible, archive, at least 30 days prior to the full proposal due date. For No Due Date (NoDD) programs the 30-day rule applies to the submission date of the proposal rather than the due date. The calendar of record for data released in the PDS is the PDS Data Release Calendar .
Proposals submitted to this Program Element must follow all formatting and content requirements that are described in program element C.1 and Section IV(b)ii of the ROSES Summary of Solicitation.
Proposals submitted to this Program Element must include an Open Science and Data Management Plan (OSDMP).(See Appendix C.1, Section 3.7).
