DAWN - image of the day - January 2017

The 6-mile-wide (10-kilometer-wide) Oxo Crater stands out on the dark landscape of Ceres in this view from NASA's Dawn spacecraft. Oxo is one of several sites at which ice has been identified by Dawn's visible and infrared mapping spectrometer. The crater is located at mid-latitudes (42 degrees North, 0 degrees East), and the presence of ice there is consistent with the recent mapping of hydrogen by Dawn's GRaND instrument (Gamma Ray and Neutron Detector). Ice is likely to be present at shallow depths in this region, waiting to be exposed via small impacts or landslides, as is believed to be the case for Oxo. Ice is not stable for long periods of time on Ceres' surface, thus its exposure at Oxo must be a relatively recent event.
