My Tweets this week

If you'd like to see these in real time, Follow me at Twitter. A word on some conventions: "RT" means "Retweet" -- I'm repeating something that somebody else said. Anything preceded by an "@" symbol is the username of someone else on Twitter. Twitter is a microblogging service that limits updates to 140 characters in length; I use it primarily to post links to stories I don't have time to write about here on the blog and to mention really really tiny bits of news that aren't worth full blog entries.

RT @LRO_NASA: Orbit #1141 about the Moon! Final insertion burn today successful & my mission orbit of 50km above the Moon is stable.

I've gotten what I can out of the 3 Moon water papers. They contradict each other in places, which is fun. Looking forward to the briefing.
