Dawn Gravity Science


Ceres L-0 (raw)

Status: Archived

This data set contains archival raw, partially processed, and ancillary/supporting gravity science data acquired during the Dawn mission while the spacecraft was in orbit around the asteroid Ceres. The radio observations were carried out using the Dawn spacecraft and Earth-based receiving stations of the NASA Deep Space Network (DSN). The data set was designed primarily to support generation of high-resolution gravity field models for Ceres.

Ceres L-2 (reduced)

Status: Archived

This data set contains archival results from gravity investigations conducted during the Dawn mission while the spacecraft was in orbit around the asteroid Ceres. Radio measurements were made using the Dawn spacecraft and Earth-based stations of the NASA Deep Space Network (DSN). The data set includes a spherical harmonic model of Ceres's gravity field generated by the Jet Propulsion Laboratory, radial gravity acceleration map, and Bouguet map; these results were derived from raw radio tracking data.

Note on the coordinate system utilized for the Ceres gravity field:
The V1.0 version of the data set differs slightly from the coordinate system used in other Dawn Ceres map products delivered to PDS. The coordinate system used for the Ceres V1.0 gravity data products is described in the data product labels. A V2.0 version of the Ceres L-2 gravity data products is in preparation and will align the coordinate system with the one utilized by other Dawn Ceres map products.
