NASA extends mission over dwarf planet Ceres for second time
NASA has authorised a second extension of the Dawn mission at Ceres, the largest object in the Mars-Jupiter asteroid belt. During the extension, the spacecraft will descend to closest-ever altitudes of 200 km above the dwarf planet, which it has been orbiting since March 2015. The mission would study Ceres' uppermost layer for ascertaining the quantity of ice present.
