NASA Dawn Mission

Asteroid Vesta and dwarf planet Ceres are 2 most massive residents of the asteroid belt. Though the 2 proto-planets lie close to eachother, Vesta is a rocky body like the inner solar system bodies while Ceres is believed to contain large quantities of ice like the bodies in the outer solar system. The mission objective of Dawn is to study Vesta and Ceres and compare the different evolutionary path each took as well as to get a overall picture of the early solar system. Dawn spacecraft has been launched on 27th Sept,2007.
