PASADENA, Calif., March 21 (UPI) -- NASA says its Dawn spacecraft has revealed unexpected details on the surface of the giant asteroid Vesta, including some never seen before on an asteroid.
Vesta is one of the brightest objects in the solar system and is visible to the naked eye from Earth, and the orbiting Dawn spacecraft has found that some areas on Vesta can be nearly twice as bright as others, giving clues to the asteroid's history, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Wednesday.
