NASA is not focusing completely on Mars exploration, but looking past Mars as well. The Spacecraft Dawn was launched Thurs. Sept. 27 with a destination of the asteroid belt past Mars. Its mission is to explore Vesta a large asteroid and Ceres a dwarf planet. The trip is a long ways, however, and Dawn will not reach Vesta until 2011 and Ceres in 2015. It will take readings on different geographical and composition features.
