"We Begin Bombing the Moon in Five Minutes"

I know some of you may be wondering what NASA's LCROSS mission (aka "bombing the moon") has to do with Seattle, and it is simply this: If the moon happens to crack open after impact, that stuff is going to go everywhere.

"This is a completely unique mission that will excavate two large holes dozens of meters across on the lunar surface. It will give us composition measurements we wouldn't otherwise be able to get," said Tim McClanahan, from Goddard Space Flight Center.

And it may end life as we know it. Good night, moon. (It's almost as bad as CERN sucking us into a black hole.)

Here is the deal: NASA is winding up its Lunar CRater Observing and Sensing Satellite (LCROSS) mission with a bang. The mission launched last June 18, and its goal is to determine whether there's ice on the moon. Tonight, the spacecraft will separate from its upper-stage Centaur rocket, and the rocket will impact a crater at the lunar south pole at about 4:30 a.m.PDT.

Cue moon dust. The spacecraft will shoot through the plume and analyze the shit out of it in a hurry, because four minutes later it's due to smack into the moon itself. (It's got two near-infrared spectrometers, a visible light spectrometer, two mid-infrared cameras, two near-infrared cameras, a visible camera and a visible radiometer, says NASA.)

The idea is that once the moon dust hits the sunlight above the crater rim, anything water-esque will vaporize and the instruments will catch the results. NASA says, in all seriousness, that we need to know if the moon's got water because it would totally help with manned interplanetary trips.

CHS says you can see the moon go boom from Cal Anderson Park (assuming clear skies), but if you've noticed how cold it is at night lately, you can watch it stream on UWTV or NASA TV.
