Dawn Reveals Secrets of Giant Asteroid VestaPasadena CA (JPL) Apr 26, 2012 Findings from NASA's Dawn spacecraft reveal new details about the giant asteroid Vesta, including its varied surface composition, sharp temperature changes and clues to its internal structure. The findings were presented at the European Geosciences Union meeting in Vienna, Austria, and will help scientists better understand the early solar system and processes that dominated its formation. Images from Dawn's framing camera and visible and infrared mapping spectrometer, taken 420 miles (680 kilomet ... read more |
