Dawn is an unmanned NASA space probe. It has orbited and studied the asteroid Vesta, and it is currently orbiting the dwarf planet Ceres. Both Vesta and Ceres are in the asteroid belt. Dawn is the first spacecraft to visit Ceres and the first to visit Vesta. It also is the first spacecraft to orbit two extraterrestrial bodies.
Dawn was launched on September 27, 2007 at Cape Canaveral Air Force Station aboard a Delta 7925-H rocket. It then travelled to Mars for a gravity assist, making its closest approach to Mars in February 2009.
