Dawn entered orbit around Vesta on July 16, 2011, and completed a 14-month survey mission before leaving for Ceres in late 2012. It then entered orbit around Ceres on March 6, 2015. NASA considered, but decided against, a proposal to visit a third target. On October 19, 2017, NASA announced that the mission would be extended until the probe's hydrazine fuel supply was used up. On November 1, 2018, NASA announced that the Dawn spacecraft had finally exhausted all of its hydrazine fuel, thus ending its mission. The satellite is currently in an uncontrolled state about Ceres.
