Living up to all the ambitions of its official name, OSIRIS - REx would explore the origins of asteroids and thus the solar system itself, connect spectral colors observable from Earth to specific
minerals on the asteroid, identify potential resources such as water for rocket fuel, help evaluate the threat of asteroids to Earth, and return some regolith (asteroid soil) for detailed analysis.
While exposed water ice would not be stable at the surface of Ceres at its relatively close distance to the Sun, water and ammonia do appear to be bound up in crustal
