Dawn Mission to Vesta & Ceres

The Dawn spacecraft will make an eight-year journey to the main asteroid belt between Mars and Jupiter in an effort to significantly increase our understanding of the conditions and processes acting at the solar system�s earliest epoch by examining the geophysical properties of the asteroid Vesta and dwarf planet Ceres. 

Evidence shows that Vesta and Ceres have distinct characteristics and, therefore, must have followed different evolutionary paths. By observing both, with the same set of instruments, scientists hope to develop an understanding of the transition from the rocky inner regions, of which Vesta is characteristic, to the icy outer regions, of which Ceres is representative.

Accellerating upwards, the Delta II 7925H rises out of the smoke, flame and steam of the launch

 

Rising into the dawn, Delta begins the roll program On a 93 degree launch azimuth, the Delta II 7925H climbs out in mid roll program.
