The Dawn Spacecraft, which has been orbiting the asteroid Ceres, has been given new life.
NASA has authorized a second extension of the Dawn mission at Ceres, the largest object in the asteroid belt between Mars and Jupiter.
It will continue at Ceres for the remainder of its science investigation and will remain in a stable orbit indefinitely after its fuel runs out.
The Dawn flight team is studying ways to maneuver Dawn into a new elliptical orbit, which may take the spacecraft to less than 120 miles (200 kilometers) from the surface of Ceres at closest approach.
A priority of the second Ceres mission extension is collecting data important for understanding the composition of Ceres' uppermost layer and how much ice it contains.
