This may be the Space Prizes blog, and this is a big Space Prize weekend for the Northrop Grumman Lunar Lander Challenge, but there's no way with dad activities I can keep you up to date with the action as reported by The Launch Pad (numerous posts), Cosmic Log, RLV News (numerous posts), News Scientist, and others. Check out those links for the background and latest news on the attempt. It looks like it's happening right now in a break in the weather. The Launch Pad also notes many twitter accounts that are active and at the site in this post. I have many of these accounts in the "Space Prizes Tweets" on the right side panel here - but you only get the most recent couple posts from each account, the panel takes a while to pop up, and it doesn't like refreshes (and with this event to keep up to date you will want to refresh).
Note: I also just added unrocket (Unreasonable Rocket twitter) to both the twitter list and tweet panel.
