NASA’s Dawn Sees Crescent Ceres

NASA’s Dawn spacecraft took this image of Ceres’ south polar region on May 17, 2017. Launched on Sept. 27, 2007, Dawn was NASA’s first truly interplanetary spaceship.

Lab Work Digs Into Gullies Seen on Giant Asteroid Vesta by NASA’s Dawn

Known as flow formations, these channels could be etched on bodies that would seem inhospitable to liquid because they are exposed to the extreme vacuum conditions of space. Pocked with craters, the surfaces of many celestial bodies in our solar system provide clear evidence of a 4.6-billion-year battering by meteoroids and other space debris.
