Space cadets! Tired of meteors and space station flyovers obscured by clouds? Just before dawn Tuesday, we can watch 2007's second total eclipse of the moon get cut short by moonset. The full August "Fruit Moon" will begin to slip into the Earth's shadow at 4:40 a.m. EDT. Totality begins at 5:52 a.m. But that's only 30 minutes before the eerily dim moon sets into the western horizon. The next lunar eclipse we'll see start to finish? On the evening of Feb. 20, 2008 ... unless it's cloudy.
