NASA spacecraft Dawn, the largest probe ever launched by the agency, is slowly approaching protoplanet Vesta, where it will spend a year in exploratory orbit before moving on to Ceres.NASA's pioneering Dawn spacecraft, a year late in being launched and 20% over budget, is slowly creeping up on the protoplanet Vesta and is expected to enter orbit around it about July 16, the first stop on a remarkable journey that will later take the craft to the larger dwarf planet Ceres.
