LCROSS impacts today!

Remember Deep Impact? One space scientist commented at the time, “I can’t believe they pay us to have this much fun.” And it seems that they’ve managed to convince NASA to have more fun crashing stuff into other bits of our solar system – with the target this time being the Moon.
The impact plume kicked up by LCROSS when it impacts inside the crater Cabeus, near the Moon’s South Pole, will hopefully confirm the presence of small amounts of ice in the lunar subsurface.
The time of impact is around 11:30 UTC, which conveniently works out as lunchtime here in the UK. NASA and SLOOH are both providing live feeds of the event, that will hopefully include live pictures of the impact itself, and not just lots of gleeful scientists in mission control giggling that 5 year-olds (something which Twitter will happily provide). Still, I plan to tune in as I munch on my lunch. The actual scientific results, of course, will probably take a while to come out, so the immediate appeal is just seeing a big explosion…
