Prometheus: over easy
Looking for all intents and purposes like a celestial egg after a session in Saturn's skillet, Prometheus displayed its pockmarked, irregular surface for Nasa's Cassini spacecraft on 27 January 2010.

Prometheus is one of Saturn's innermost moons. It orbits the gas-giant at a distance of 139 353 km and is 86 km across at its widest point. The porous, icy-bodied world was originally discovered by images taken by Voyager 1 back in 1980. You could say this latest "egg-cellent" view has the Cassini science team licking their chops at the thought of future Prometheus images.

This raw, unprocessed image of Prometheus [pro-MEE-thee-us], taken in visible light, was obtained by Cassini's narrow-angle camera at a distance of approximately 36 000 km.

The Cassini Equinox Mission is a joint United States and European endeavour. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for Nasa's Science Mission Directorate, Washington, DC. The Cassini orbiter was designed, developed and assembled at JPL.
