PASADENA, Calif., April 19 (UPI) -- NASA says it is extending by 40 days its Dawn spacecraft mission exploring the giant asteroid Vesta, the second-most-massive object in the main asteroid belt.
The mission extension will allow Dawn to continue its scientific observations at Vesta until Aug. 26, while still arriving at its second destination, the dwarf planet Ceres, at the same originally scheduled target date in February 2015, the space agency said in a release Thursday.
