"The LCROSS Centaur and Spacecraft impacted the moon at approximately 4:30 a.m. PDT. Scientists are reviewing the initial data and will report what they know at a Post Impact News Conference at 7:00 a.m. PDT / 10:00 a.m. EDT on NASA TV."
This is an interesting experiment. Under lunar conditions, the plume of debris from the impacts could soar 10km high, offering an unparallelled opportunity to analyze its composition.
COMMENT: I don't expect they will find water ice in sufficient quantities to support a lunar base for humans, but any water will be a major discovery.
Then for comic relief, we have conspiracy theorists who claim we are testing a new kind of bomb. Guys... wouldn't it be a lot cheaper to test a bomb on Earth rather than spend thousands of dollars per kg to haul it to the Moon?
