The above video begins with a sequence above Divalia Fossa, an unusual pair of troughs running parallel over heavily cratered terrain. Next, the virtual spaceship explores Vesta’s 60-km Marcia Crater, showing numerous vivid details. Last, Dawn images were digitally recast with exaggerated height to better reveal Vesta’s 5-km high mountain Aricia Tholus. Currently, Dawn is rising away from Vesta after being close enough to obtain the most detailed surface images and gravity measurements of the Solar System’s second largest asteroid. I
