Galileo Encounter with 951 Gaspra: First Pictures of an Asteroid
Galileo images of Gaspra reveal it to be an irregularly shaped object (19 by 12 by 11 kilometers) that appears to have been created by a catastrophic collisional disruption of a precursor parentExpand

Geological evidence for solid-state convection in Europa's ice shell
The ice-rich surface of the jovian satellite Europa is sparsely cratered, suggesting that this moon might be geologically active today. Moreover, models of the satellite's interior indicate thatExpand
