Intriguingly, that means water could potentially reach the surface from a deep crater, where there was less ice to get through — perhaps even from a crater like the one where Dawn saw the bright spot.

Jupiter's largest moon, Ganymede, has solidified its membership in the growing cadre of solar system locales where liquid water flows beneath the surface.
