Ceres' surface shows evidence for different types of flows that indicate the presence of ice in the regolith (as described in PIA21471).

One type of flow encircles the large impact crater at right in this image. Scientists see features in this flow that indicate a low degree of internal friction within its material, meaning it was able to flow easily and far from its source. This could be due to the incorporation of a significant amount of liquid water or water vapor into the ejecta blanket. This flow also shows a large ridge along its edge (seen most clearly just to the left of the large crater). These features are commonly associated with flows on Mars called "fluidized ejecta blankets" (see for example PIA04947).

This feature is located southwest of Kerwan crater at 40 degrees south latitude, 109 degrees east longitude. This is in the vicinity of the latitudes where Dawn's gamma ray and neutron spectrometer (GRaND) instrument sensed the presence of ice in the first meter of Ceres' regolith (see PIA21081).

The image was taken on August, 7, 2016 from an altitude of about 240 miles (390 kilometers) above Ceres. The image resolution is about 120 feet (35 meters) per pixel.

Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK, Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.
