New NASA spacecraft to investigate moon mystery

CAPE CANAVERAL, FLORIDA, Sept 6:  More than 40 years after the last Apollo astronauts left the moon, NASA is preparing to launch a small robotic spacecraft to investigate one of their most bizarre discoveries. Crews reported seeing an odd glow on the lunar horizon just before sunrise. The phenomenon, which prompted a notebook sketch by Apollo 17 Commander Eugene Cernan, was unexpected because the airless moon lacked atmosphere for reflecting sunlight. (agencies)
