These are very cool high-resolution photos of Mars that show detail of the planet and surface features, many of which clearly indicate erosion caused most likely by liquid water. (Not the latest b/w photos that just came back from the first lander Spirit.)
And might I add, a very cool site overall – I’m reading up on the current Mars lander mission ahead of the Nova special that airs later tonight. They did a great job of combining valuable written content and useful interactive features and animation into an engaging yet simple site design.
Also I noticed that they use the Chicago font in the site banner, which was the default Mac OS font up until I think Mac OS 8? Always a cool choice of typeface for that futuristic-yet-retro look.
