If you think Google Earth is cool, check out NASA WorldWind! My boyfriend is getting his master's degree in this stuff, and all the professors in his department practically salivate over this program!

"World Wind lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there.

Virtually visit any place in the world. Look across the Andes, into the Grand Canyon, over the Alps, or along the African Sahara."
