Hi Ray Nice picture of Dione. Seems Saturn Moons have a lot of their
own individual features. Dione looks a lot like our Moon. Easy to see
after Jupiter was formed how the early universe had so much meteorite
activity. Craters can last for billions of years. Its kind on nice
telling old ones from new ones. Read that Callistro's icy surface is the
most battered in the known solar system. If NASA wants to find water
they only have to look at Jupiter's Moons. Io with all its active
volcanoes must have some flowing liquid water on its surface. There has
to be great stresses on both surface,and core because Io is so close to
Jupiter,and its great orbiting speed. Not much further away than Moon
and Earth. I see Io as the most dynamic Moon of all the Moons and,makes
our Moon a cold dusty crated dry object with no action going on its
surface. Bert
