One of NASA's moon probes, the Lunar Crater Observation and Sensing Satellite (LCROSS), will complete a relatively simple mission next month: releasing a spent rocket stage toward a shadowy crater, then following it to see what the impact stirs up before crashing the mother ship itself into the crater...
Archeologists have uncovered a veritable tangle of ancient flax fibers in a cave in the Republic of Georgia. The find consists of tiny bits of flax fibers that had been spun—and in some cases dyed—by upper Paleolithic hunters who occupied the cave intermittently beginning some 32,000 years ago...
