Solar System Workings 2020

Last updated: 2/25/2020, based on the 2/24/2020 Amendment 2 to ROSES 2020.

Critical Dates

    NOI due date:                        11/13/2020

    Proposal due date:               01/09/2021

    Data Availability date:        12/10/2020


The Solar System Workings (SSW) program is described in Appendix C.3 of the ROSES 2020 NRA. See the NSPIRES website.

This is a very wide ranging call. While we provide a brief synopsis here, proposers must refer to the call for specifics.

"The Solar System Workings (SSW) program element supports research into atmospheric, climatological, dynamical, geologic, geophysical, and geochemical processes occurring on planetary bodies, satellites, and other minor bodies (including rings) in the Solar System. This call seeks to address the physical and chemical processes that affect the surfaces, interiors, atmospheres, exospheres, and magnetospheres of planetary bodies."

Data Sources

The specific data availability and restrictions given for the 2020 SSW are given in Sections C.3 and C.1 of ROSES 2020.

In order to determine which volumes at the Ring-Moon Systems Node meet the SSW basic eligibility requirements for publicly available timing (based on the Step 2 Proposal due date), see the Data Status tab.

Finding SSW Relevant Data within the PDS

Data at the Ring-Moon Systems Node.
  • Search for data
  • our Outer Planets Unified Search tool OPUS, allows users to search for and obtain subsets of data based on a wide range of constraints. OPUS supports Cassini CIRS, ISS, UVIS and VIMS data, New Horizons LORRI and MVIC data, Galileo SSI data, Voyager ISS data, HST ACS, NICMOS, STIS, WFPC2 and WFC3 data. The results returned include preview products and tables of metadata.

  • Browse our Data Directories
  • Download entire volumes as tar.gz files.
  • Use our Mission Information Pages
  • Our mission information pages provide overviews of data sets and instruments along with links to detailed descriptions of the instruments and to the data and to Ring-Moon Systems Node generated browse images and footprint diagrams.

    • Galileo. Our Galileo page supports the Solid State Imager (SSI) and the Near-Infrared Mapping Spectrometer (NIMS).
    • Voyager. Our Voyager pages support ISS including new data sets of uncompressed, calibrated and geometrically corrected images, IRIS, and occultation data from PPS, UVS, and RSS. These pages also provide access to the Voyager SPICE kernels generated at the Ring-Moon Systems Node.
    • HST. Our HST page describes our HST holdings including the volumes in our "HST Observations of the Outer Planets" project which provide references to HST observations made with the ACS, NICMOS, STIS, WFPC2, or WFC3 that included an outer planet system. The volumes are updated periodically.
    • Uranus Ring Plane Crossing . While publicly available URPX observations obtained under Planetary Astronomy Program are covered by this NRA, we do not currently have any such data. If eligible URPX data becomes available at the Ring's Node prior to the proposal deadline, this page will reflect it.

    Additional links within PDS

    • For more information about proposing with respect to PDS archiving, see the PDS Engineering Node's Information for Proposers page.
    • From that page, follow the link to the Proposers to Individual R&A Programs page which contains links to several additional resources including one to the Proposer's Archiving Guide, written specifically to support DAP proposers, and links to ROSES support pages at the individual nodes.
    • The PDS NAIF Node and observation geometry.
    • SPICE data and software may be obtained from the NAIF web site. SPICE data files contain spacecraft and solar system geometry data necessary to interpret scientific observations from space-based instruments. The SPICE system also includes a large suite of software, mostly in the form of subroutines, that users incorporate in their own application programs to read SPICE files and to compute derived observation geometry, such as altitude, latitude/longitude, and lighting angles.
