A team of scientists, led by Shuai Li of the University of Hawaii and Brown University, used data from NASA's Moon Mineralogy Mapper to confirm the water ice at the moon's dark and cold north and south poles. "Most of the newfound water ice lies in the shadows of craters near the poles, where the warmest temperatures never reach above -250 degrees Fahrenheit. Because of the very small tilt of the Moon's rotation axis, sunlight never reaches these regions," NASA said in a statement. Previous observations found possible signs of surface ice on the lunar south pole. This latest discovery...
