To commemorate the NASA Apollo 11 mission Google has launched Google Moon which uses Google Earth imagery to explore the moon. This will really come in handy if you ever are lost on the moon. But seriously, they have some pretty fascinating satellite images of the big chunk of cheese. See for yourself here, and be sure to zoom in all the way.
I'd love to see Google take it step further and explore the ocean's of Earth and show us some of the deeper depths that have never been explored by the human eye. That would be incredible.
