Dawn 's images led to widespread reports in the media about the bright spots, including in news sources, [22] astronomy magazines, [23] and science magazines. [24] An informal NASA poll during May offered the following ideas for the nature of the spots: [25] ice, volcanos, geysers, salt deposits, rock, or other. [26]
Dawn was launched in September 2007 with the mission of studying Ceres and the asteroid 4 Vesta. The spacecraft entered orbit around Vesta on July 16, 2011, and completed a 14-month survey mission before leaving for Ceres in late 2012. It went into orbit around Ceres on March 6, 2015.
