Mars

Astronomy Picture of the Day has a wonderful panoramic shot of Mars from the rover Spirit. Click here to check it out.

I also picked up a book called Roving Mars: Spirit, Opportunity, and the Exploration of the Red Planet by Steve Squyres. He is the principal scientific investigator from the mission. Dr. Squyres is the perfect example of a passionate scientist. He practically exudes excitement about the study of Mars. I'm hoping to get to listen to him personally in February when he gives a presentation at the University of Washington. Anyway, check both out; they're excellent.
