And what better time to read about this crazy material called "aerogel": it's basically a glass foam sponge with nanometer-scale cells. It has the density of air, and barely conducts heat. It's used in space shuttle tiles, and now they're using a giant scoop of the stuff to catch comet particles. More cool pictures here (the brick one is especially cool.) Lots more details at LBL.
I'm sure you've heard that the Spirit Mars rover successfully landed today. Up-to-the-minute updates are at spaceflightnow.com, including pictures.
