KENNEDY SPACE CENTER, FLA. -- In the Astrotech Space Operations facility, Orbital Science technicians install a computer chip on the Dawn spacecraft. The silicon chip holds the names of more than 360,000 space enthusiasts worldwide who signed up to participate in a virtual voyage to the asteroid belt and is about the size of an American five-cent coin. Dawn's mission is to explore two of the asteroid belt's most intriguing and dissimilar occupants: asteroid Vesta and the dwarf planet Ceres. Dawn is scheduled to launch June 30 from Launch Complex 17-B. Photo credit: NASA/Jim Grossmann
