Here's a couple of great photo albums from yesterday's Northrop Grumman Lunar Lander Challege:
Photo Album: 2008 NGLLC, Day One - The Launch Pad - Will Pomerantz gets a rare perspective on the events.
LLC Day 1 in Pictures - Personal Spaceflight
RLV News is ready for the day, and gives a number of links to start the day right:
NG-LLC and Armadillo/RRL suborbital space
Space VidCast.com coverage starts in 14 minutes as I'm writing. If that doesn't work, try here.
The GLXP Twitter has also been a good source.
I plan to update this post once or twice later today as events unfold, but these are the kinds of primary sources you should check for the best coverage.
Update: Well, it looks like the day's first attempt didn't work, and Armadillo isn't going to try again today. That's it for now, but Peter Diamandis discussed the possibility of an early Spring rematch with John Carmack and the Space VidCast hosts. See the above sites for more details.
