Title:
Ancient Cratered Plains on Ganymede
Explanation:
The largest moon in the Solar System shows regions that are ancient and battered. The high density of craters demonstrate that patches of Ganymede [ http://antwrp.gsfc.…] are indeed billions of years old. This photo [ http://antwrp.gsfc.…] is one of a series [ http://antwrp.gsfc.…] released by NASA [ http://newproducts.…] two days ago from the Galileo spacecraft orbiting Jupiter [ http://galileo.ivv.…]. The large impact crater on the left is 19 kilometers across, while dark indentations in Ganymede [ http://newproducts.…]'s crusty surface-ice run diagonally. Ganymede [ http://antwrp.gsfc.…] is composed of half rock and half water-ice. The Galileo spacecraft [ http://nauts.com/hi…] will continue to orbit Jupiter [ http://quest.arc.na…] over the next 16 months and send back data about Jupiter [ http://hea-www.harv…] and its four largest moons: Io [ http://antwrp.gsfc.…], Europa [ http://antwrp.gsfc.…], Ganymede [ http://antwrp.gsfc.…], and Callisto [ http://antwrp.gsfc.…].
