Craters On Vesta, Ceres Could Point To Jupiter’s Age

The goal of NASA's Dawn mission is to capture the earliest moments of the Solar System, investigating the conditions and processes that gave rise to the formation of planets. It will help determine the nature of the building blocks from which the terrestrial planets were formed, in particular the connection between size and water presence. The primary mission objective is to study two of the largest protoplanets remaining intact since their formation, Ceres and Vesta, which reside in the so-called "asteroid belt", a densely populated with small bodies zone between Mars and Jupiter.
