Dawn at Ceres - Framing Camera

The Dawn spacecraft is visiting the dwarf planet Ceres for the time period Dec. 26, 2014 through the end of the mission (planned for summer 2016). Framing Camera 2 is one of two identical units flying on the Dawn spacecraft, and the only one acquiring science data at Vesta and Ceres. The data sets linked below will include raw (level 1a) and calibrated (level 1b) versions of all available images acquired during the Ceres Encounter. So far, the Approach and RC3 L1a data are available. An updated Calibration volume with added calibraton files derived from the Vesta-Ceres cruise is also available.


Raw Data (Level 1a)

Status: Certified and released with minor liens as of Oct. 16, 2015



Data set id: Browse: Download:
Dawn Ceres FC2 raw, Approach and RC3 DWNCAFC2_1A (19 Gb) DWNCAFC2_1A-151016a.tgz (5.6 Gb)
Updated FC2 Calibration volume DWNCALFC2 (431 Mb) DWNCALFC2-151016.tgz (223 Mb)

Caution: These data volumes have been certified and released with known issues, which will be resolved during the liens resolution phase. Before making use of these data, please read the known issues below.


Known issues

These known issues are applicable to the Dawn FC2 Ceres data volumes linked above. Please read these before using the data.

1. The document describing the Dawn Ceres coordinate system has not yet been included on the volume. This document may be downloaded here. The coordinate system described in this document corresponds with that of the planetary constants kernel dawn_ceres_v05.tpc, which is available on the NAIF Dawn SPICE archive.

2. The Approach, RC3, and Survey data linked above are labeled in an earlier version of the Ceres coordinate system which differs slightly from that described in the Ceres coordinate system document. The planetary constants kernel used to label the Approach, RC3, and Survey data is dawn_ceres_v04.tpc, which is available on the NAIF Dawn SPICE archive.

3. When using the Framing Camera data in conjunction with the Dawn VIR data, be aware that the VIR data describes longitude with the 0 to 360 degree convention, whereas the FC data describes longitude with the -180 to 180 degree convention. This mismatch will be corrected during the liens resolution by the conversion of the FC data to the 0 to 360 degree convention.

4. The PDS external peer review of the data volumes found a number of additional minor liens which have not yet been corrected but which will be corrected before final archiving. The list of these liens may be downloaded here.
