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).
<p>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.
