Title:
Callisto Full Face
Explanation:
Callisto [ http://www.nineplan…]'s surface shows its age. While probably formed at the same time as Io [ http://www.nineplan…], the difference between the surfaces of these two moons of Jupiter [ http://www.solarvie…] could hardly be greater. Io's surface [ http://antwrp.gsfc.…] is young, shows practically no impact craters, and is continually being repaved by the lava exploding [ http://antwrp.gsfc.…] from its many large volcanoes. Callisto [ http://www.jpl.nasa…]'s surface is old, shows the highest density of impact craters [ http://www.lpi.usra…] in the Solar System [ http://www.explorat…], and harbors no volcanoes [ http://volcano.und.…] or even any large mountains. Callisto's surface [ http://www.nature.c…] is one large ice-field, laced with cracks [ http://antwrp.gsfc.…] and craters [ http://antwrp.gsfc.…] from billions of years of collisions with interplanetary debris [ http://antwrp.gsfc.…]. The above image [ http://photojournal…] was taken in 2001 May and is, so far, the only complete global color image taken by the Jupiter-orbiting Galileo spacecraft [ http://galileo.jpl.…].
