"Where's the kaboom? There was supposed to be an Earth-shattering kaboom!"
OK, I guess LCROSS "worked" in the sense that the impactor (presumably) threw up a cloud of debris that the probe could send back information on as it made its own plunge to the surface, but it was a little anticlimactic. I was hoping for a visible flash from the impact. (Heck, even when the LHC was starting up and had its own live webcast, there was a flash on a fluorescent screen as the proton beams made it through each sector, so even a casual viewer could see exactly when something had happened.)
Oh well, it'll be interesting, over the next few days, to see what the analysis of the spectral data reveals.
