NASA is pulling something cute right now: a March Madness-like mission playoff, where readers can vote on certain NASA missions to move on to the next level. Eventually, on April 8, a winner will be announced. Round 1 voting started yesterday (March 19) and runs through today. The next round starts on the 23rd. I've already been getting emails from people on various missions asking me to plug their particular pony, but that wouldn't be fair. I know people from a lot of those missions, and worked on one or two myself. Plus, BABloggees are a discerning group, and I suspect you can figure this out on your own.
