A couple of posts ago we showed how to use content from the Geography Network and the USGS PIGWAD site to turn ArcGIS Explorer into a Mars Explorer.

George Dailey, ESRI Education Manager, ups the ante and takes things further in a recent post on the GIS Education Community blog. We really like the use of both online and local content, and also popup photos from the NASA Photojournal site. Check out these cool screenshots.
