This close-up view of Hakumyi crater , as seen by NASA's Dawn spacecraft, provides insight into the origin of the small crater and lobe-shaped flow next to its southern rim. The sharp edges of these features indicate they are relatively recent with respect to the more subdued Hakumyi, which is 43 miles (70 kilometers) wide. The lobate flow ends in a tongue-shaped deposit. A more discrete feature slightly west (left) of the large lobe-shaped flow suggests an ancient or partially developed lobe.
These kinds of flow features, which typically are found at high latitudes on Ceres, are expressions of what is termed "mass wasting," meaning the downslope movement of material. This process is initiated by slumping or detachment of material from crater rims. Here the process seems to have been triggered by small craters whose remnant shapes can be discerned at the top of each flow.
Dawn took this image from its low-altitude mapping orbit, or LAMO, at a distance of about 240 miles (385 kilometers) above the surface. The center coordinates of this image are 52 degrees North latitude and 26 degrees east longitude.
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, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.
