| Data Set Name | Data Set Description | Data Resource Page | Citation |
| DAWN GRaND Vesta Maps | A global map of the abundance of hydrogen in micrograms/g within the regolith of asteroid 4 Vesta is provided for two-degree equal-angle pixels. Hydrogen abundances were determined from epithermal neutron counting data acquired by the NASA Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low altitude mapping orbit, about 210 km from Vesta's surface. | Browse | "Lawrence, D.J., Dawn GRaND fast neutron residual counting rate map, DAWN-A-GRAND-5-VESTA-FAST-RESIDUAL-V1.0, NASA Planetary Data System, 2014." |

| DAWN GRaND high-energy gamma-ray counting rate map | This data product describes a map of the high-energy gamma-ray (HEGR) count rate across the surface of Vesta. As shown in PEPLOWSKIETAL2013, HEGRS are sensitive to the bulk elemental composition of the near surface material, particularly its heavy major-element content. | Browse | "Peplowski et al., Dawn GRaND high-energy gamma-ray counting rate map, DAWN-A-GRAND-5-VESTA-HEGR-COUNTS-V1.0, NASA Planetary Data System, 2013." |
| DAWN GRaND Map Vesta Gamma Fe Corrected Counts | This data set provides tables of net counting rates of Fe gamma rays at 7.6 MeV measured by the BGO detector of Dawn's Gamma Ray and Neutron Detector acquired at the low altitude mapping orbit. The counting rates were normalized for variations of live time, solid angle of Vesta, and galactic cosmic ray intensity. They were also corrected for variations of neutron number density derived from thermal and epithermal neutron observations by GRaND | Browse | "Yamashita N., T.H. Prettyman, D.W. Mittlefehldt, M.J.

| DAWN GRaND Map Vesta Neutron Absorption | A global map of a unitless compositional parameter, delta-C_perpendicular (DCP), and propagated 1-sigma uncertainties is provided. DCP varies linearly with the macroscopic thermal neutron absorption cross section of Vesta's regolith. An equation for converting tabulated DCP values to absorption units is provided in this document. DCP was determined from thermal and epithermal neutron counting rates measured by the NASA Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low altitude mapping orbit, about 210 km from Vesta's surface. | Browse | "Prettyman, T.H., Dawn GRaND absorption map, DAWN-A-GRAND-5-VESTA-ABSORPTION-V1.0, NASA Planetary Data System, 2014." |
| DAWN VIR Derived Vesta Global Mosaics | This data set contains global mosaics of the Dawn VIR band centers and depths of pyroxene absorption bands, located at 0.9 (band I) and 1.9 microns (band II), from the Vesta encounter. The data set was acquired during the (High Altitude Mapping Orbit(HAMO), Low Altitude Mapping Orbit (LAMO), and HAMO-2) mapping phases between 2011-09-30 and 2012-07-24 . | Browse | "De Sanctis, M.C., M.T.

| Low resolution rotationally resolved spectra of Vesta | This data set contains low-resolution near-infrared (~0.7-2.5 microns) spectra of main belt asteroid (4) Vesta observed with the SpeX instrument on NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawai'i, and reported in Reddy et al. (2011). This data set archives reduced, calibrated spectra that were obtained as part of ground-based characterization of Vesta prior to the arrival of Dawn spacecraft. | Browse | "Reddy, V., Reddy Vesta Rotationally Resolved Near-Infrared Spectra V1.0.

| DAWN Framing Camera 2 Vesta global digital terrain model | This data set contains the Vesta digital terrain model based on the Dawn High Altitude Mapping orbit (HAMO) Framing Camera 2 (FC2) images and derived by using the stereo photo-grammetric (SPG) method. The HAMO DTM covers approximately 95% of the Vesta surface (few permanently shadowed areas near the poles required interpolation). The a DTM has a lateral spacing of ~70 m/pixel (64.0 pixel/degree) and a vertical accuracy of +/-6 m. | Browse | "Preusker, F., F. Scholten, K.-D Matz, T. Roatsch, R. Jaumann, C.A. Raymond, and C.T.

| DAWN Framing Camera 2 Vesta global mosaics derived from HAMO and LAMO | This data set includes various Vesta global mosaics derived from images acquired by the Framing Camera 2 (FC2) on the NASA Dawn spacecraft at the high and low altitude mapping orbits (HAMO and LAMO). Data are provided in cylindrical and polar stereographic projections. In addition to the mosaics, the flatfield and stray light used during the processing of the raw images are provided. | Browse | "Roatsch, T., E. Kersten, K.-D. Matz, F. Preusker, F.

| DAWN Vesta Gravity Models | 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. | Browse | "Konopliv, A.S., Park, R.S., Asmar, S.W., and Buccino, D.R., Dawn Vesta Derived Gravity Data, NASA Planetary Data System, DAWN-A-RSS-5-VEGR-V2.0, 2017." |
