NASA launched Dawn in 2007 to learn more about the beginning of the solar system. During its mission, the spacecraft studied the asteroid Vesta and dwarf planet Ceres, celestial bodies believed to have formed early in the history of the solar system.
The mission aided scientists in characterizing the early solar system and the processes that dominated its formation. Dawn is the only spacecraft to orbit two deep-space destinations, a feat enabled by the efficiency of the spacecraft’s ion propulsion system.
