This is a very cool program, very similar to Google Earth, but with a lot of unique features that give you other ways to look at our little rock in the universe. Ocean temps, topo maps, a lot of interesting stuff to play with. They even let you jump over to the moon and expore it in a similar fashion. The closeup views don’t seem to be as detailed as Google Earth, but it seems worthwhile to have both programs. They are both free.
