(06/27/2007) --- KENNEDY SPACE CENTER, FLA. -- At the top of Launch Pad 17-B, at Cape Canaveral Air Force Station, workers help to guide NASA’s Dawn spacecraft into position for stacking with the Delta II launch vehicle. Launch is scheduled for July 7. Dawn is the ninth mission in NASA's Discovery Program. The spacecraft will be the first to orbit two planetary bodies, asteroid Vesta and dwarf planet Ceres, during a single mission. Vesta and Ceres lie in the asteroid belt between Mars and Jupiter. It is also NASA’s first purely scientific mission powered by three solar electric ion propulsion engines. Photo credit: NASA/Troy Cryder.
