More Mars!
A very cool website courtesy of the folks at Google: Mars. Sure, they may trample on free speech to cozy up to China, but at least they can make pretty pictures available to all.
You can click on spacecraft up at the top and it will pinpoint all the robots that have crashed and/or landed on the ruddy planet. See if you can find where the Polar Lander died.
The main map is false-color topographical, but you can also select "visible" (black and white) and "infrared," which someone will have to explain to me, but it's actually the one I recognize the best. Zoom in on the crater of Olympus Mons. (Do a search for Olympus.) Volcanic craters upon volcanic craters.

An infrared image is another form of false-color image. The camera "sees" in the infra-red range of electromagnetic radiation, like 1-10 microns. Then the image processing converts the IR image into a visible color image (0.4-0.7 microns).
