BOSTON, Aug. 30 (UPI) -- U.S. scientists say NASA's Lunar Reconnaissance Orbiter shows ice patches could make up 5 percent to 10 percent of material in the shaded walls of a crater.
Using a radar instrument on the orbiter, astronomers have estimated the amount of ice likely to be found inside the permanently shadowed Shackleton crater located near the moon's south pole, Boston University researcher Bradley Thomson, who led the research, and colleagues reported in the journal Geophysical Research Letters.
