We'll do it during a full moon, to make sure we get all of it.

One of the less subtle ways used to discover the composition of extraplanetary bodies is to take a big hunk of metal and slam it into said body's surface. Whatever lies underneath will be thrown high into space, and then we can do spectroscopy on the ejecta and discover what it's composed of. NASA plans to nuke the moon in October, but this gentleman has some concerns that we should probably take seriously.
Seriously:
"If the true intent of the LCROSS mission moon bombing is a hostile act by NASA against known extraterrestrial civilizations and settlements on the moon, then NASA and by extension the U.S. government are guilty of aggressive war which is the most serious of war crimes under the U.N. Charter and the Geneva Conventions, to which the U.S. is subject."
