Asteroid Mappers: Vesta Edition

Help us map the surface of asteroid Vesta using images from NASA' Dawn spacecraft. Measure the sizes and positions of craters and other surface features.

Why do we care about craters? Craters can tell us a lot about what’s happening on a planetary surface. One of the main uses of craters is to tell ages. The age of Vesta’s surface is really important to know, because it was probably one of the very first objects to fully form in the solar system.
