Title:
Callisto: Dark Smashed Iceball
Explanation:
Callisto [ http://seds.lpl.ari…] is a dirty battered world, showing the most beaten surface of Jupiter [ http://antwrp.gsfc.…]'s major moons. Made of a rocky core covered by fractured ice, Callisto [ http://www.c3.lanl.…]'s past collisions with large meteors are evident as large craters surrounded by concentric rings. The four largest moons of Jupiter: Io [ http://antwrp.gsfc.…], Europa [ http://antwrp.gsfc.…], Ganymede [ http://antwrp.gsfc.…], and Callisto were all discovered by Galileo [ http://galileo.imss…] and Marius [ http://seds.lpl.ari…] in 1610 with early telescopes and are now known as the Galilean satellites. The NASA spacecraft Galileo [ http://www.jpl.nasa…] is scheduled to arrive at Jupiter is December of 1995.
