When a NASA rocket slammed into the Moon last fall, scientists knew they would get information about the composition of the lunar soil at the poles that has never been sampled.

The findings from that NASA mission, called LCROSS for Lunar CRater Observing and Sensing Satellite, are out, and they are interesting to say the least.

The emptied upper stage of a rocket crashed into the Cabeus crater near the Moon's south pole last October. A second spacecraft followed to analyze the ejected debris for signs of water and other constituents of the super-chilled lunar landscape.
A numerical model can't help you finish a marathon, that will take a lot of running, but math can at least help you be the most efficient your body can be.

The best part about the night before a marathon is 'carb'ing up' the night before with a healthy pasta dinner but marathoners in training long before that make many mistakes with their diet, assuming "I'm in training" means they can eat twice as much of anything.
