Abstract

Asteroid 4 Vesta is the first rocky body visited by spacecraft with a surface gravity intermediate between the Moon and the smaller nonellipsoidal asteroids mapped to date (e.g., Eros, Lutetia). As such, it represents a unique natural laboratory in impact cratering mechanics on lowergravity planetary bodies. Dawn global mapping has revealed a rich variety of impact crater morphologies, some of which were not anticipated prior to arrival. Here we summarize some of the initial observations and preliminary interpretations regarding impact cratering processes on this transitional planetary body.
