Launched in 2007, NASA’s unmanned space probe Dawn enters orbit of Vesta, one of the largest bodies in the main asteroid belt between Mars and Jupiter. Over time, the mission plan calls for Dawn to spiral down to lower orbits to explore and map Vesta from orbit, trying to determine what secrets the large asteroid has about the earliest days of the solar system. If all goes well, Dawn will remain at Vesta until 2012, and will depart to explore another asteroid, Ceres, arriving there in 2015.
