This mosaic of Cerealia Facula is based on images obtained by NASA's Dawn spacecraft in its second extended mission, from an altitude as low as about 21 miles (34 kilometers). The contrast in resolution obtained by the two phases is visible here, reflected by a few gaps in the high-resolution coverage. This image is superposed to a similar scene acquired in the low-altitude mapping orbit of the mission from an altitude of about 240 miles (385 km).
The increased resolution afforded by the low altitude is revealing intimate details about the relationships between bright and dark materials across the facula, which will help resolve the mystery of its origin.
Cerealia Facula is located at about 19.7 degrees north latitude and 239.6 degrees east longitude.
Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorates Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. JPL 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.
