Dawn at Ceres - VIR

The Dawn spacecraft is visiting the dwarf planet 1 Ceres for the time period Dec. 26, 2014 through the end of the mission, which has been extended through 2018. VIR is an imaging spectrometer that combines two data channels in one instrument, Visible (VIS) and Infrared (IR). 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, data are available through XMO4 (Extended mission Opposition orbit).
