PDS Asteroid/Dust Archive
Dawn Gravity Science
Vesta L-0 (raw)
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 Vesta.
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 Vesta.
Vesta L-2 (reduced)
This data set contains archival results from gravity investigations
conducted during the Dawn mission while the spacecraft was in orbit
around the asteroid Vesta. 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 Vesta'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: The Vesta Gravity L2 volume has been updated to version 2 by the
addition of a Bouguet map. Some catalog files have been updated. The
volume is otherwise unchanged.
