Jupiterís large ice moon Ganymede

Jupiterís large ice moon Ganymede

Fig. 9.21 . Dark patches of ancient terrain are apparently frozen in swaths of bright, younger and translucent ice on Jupiterís satellite Ganymede, the largest moon in the solar system. More recent impact craters have splashed fresh, bright ice across the surface of the ice-covered moon. This image was taken on 27 February 2007 from the New Horizons spacecraft on it way to an expected encounter with Pluto in July 2015. (Courtesy of NASA/JHUAPL/SRI.)
