NASA's Asteroid-Orbiting Probe Might Get One Final Mission
NASA's Dawn spacecraft might get a mission extension, but no one is really sure where it would go — if it ever stops orbiting an astroid.By Ethan Weston | April 23, 2016
NASA's asteroid-hopping probe may not be done yet. Even though its mission is supposed to be over this summer, a team of scientists have asked NASA for an extension.
Dawn launched back in 2007 and spent 14 months orbiting the asteroid Vesta before moving on to its final destination, the dwarf planet Ceres. It's the first craft to orbit two targets in the cosmos.
Vesta and Ceres are considered protoplanets, which are basically baby planets from the early solar system that never formed into the real thing.
