Weekend spaciness

1) The new Carnival of Space is up at Lab Lemming's tent, and it's a BIG tent. 2) Emily has news that Phobos is a bit lighter than previously thought. What a pile. 3) Emily also has some nifty new MESSENGER images explained. I've been too lazy to deal with that. 4) Tom notes that HiRISE spotted Spirit on Mars. Massively embiggenated version is here. 4) This is dumb. So why did it make me smile so much? Oh right: I'm a dork.
