NASA’s “Moon Bombing” For Water Ice Tonight—A Quick Explanation October 8, 2009

NASA’s surprisingly controversial “moon bombing” with the LCROSS craft is set for tonight, at 4:30am!

A lot of people (and I mean a lot–Twitter has been on fire , 38 Tweets on it in past ~30 seconds) are wondering why NASA’s doing this, and some are expressing levels of outrage.

A quick explanation: Water ice is important to moon colonies (and beyond—the oxygen and hydrogen can be used to make rocket propellant, which is incredibly expensive to launch off of Earth; and thus, the Moon could be a cost-effective ‘gas station’ for Mars and beyond), and this event tonight is a key study to whether it exists in shadowed craters sensors can’t see into.  (See this great article from Universe Today for more on why water on the Moon is valuable.)

The LCROSS will drop it’s spent Centaur rocket (non-explosive, basically a large piece of metal) into the Cabeus A crater, and the LCROSS itself will follow into the crater, taking readings as it goes (and eventually impacts the same location).

The $79 million spent on the mission could pay itself back for the U.S.—private space development is a rapidly growing industry, one that Obama has suggested could be valuable to an economic turnaround. Companies are already set for a variety of commercial applications (including an extremely promising alternative energy, as explained there by Apollo 17 astronaut/geologist Jack Schmitt) , but the presence of valuable water ice gives them another lucrative motivation.

This will be a historic event—the mainstream-public attention alone has guaranteed that, and the successful discovery of water ice will be yet another spur to an already charging “base race” back to the Moon  (for resources, this time) :)

You can watch the impact live on NASA TV at 4:30am PST (and there’s even a free watching event at OMSI here in Portland, OR.)

Hope that we are not playing to much with the Mother Nature
