In case you missed it, yesterday morning, NASA slammed the LCROSS Centaur probe (and shortly thereafter the shepherding spacecraft) into the moon. Giant plumes of dust and debris were meant to fly up, something like this:
A bit disappointingly, that is not quite how it played out. The impact site was harder than anticipated, and there was little (or no, from my perspective) visible plume. Still, the important part is the spectral analysis, and while initially it’d been expected that we might have an estimate of the water on the lunar poles by an hour or so after impact, we may have to wait a while yet.
It was fun attacking the moon, however.
