While watching a rocket launch is plenty of fun, 2011 will also see a number of missions finally arrive at their destinations. July will mark the end of Dawn's four-year journey to the asteroid belt which cuts between the orbits of Mars and Jupiter. Dawn will investigate the icy dwarf planet Ceres and the rocky asteroid 4 Vesta to help researchers better understand conditions during the original formation of the solar system. This Hubble image of Ceres is one of the best we have, so you can see why researchers want to take a closer look.
