Ice Rich Crater At The Moon's North Pole

"NASA Radar returns first high-resolution view of an unusual crater near Moon's north pole Mini-RF, a synthetic aperture radar on board NASA's Lunar Reconnaissance Orbiter, recently imaged a potentially ice-rich crater near the north pole of the Moon. Located at 84°N, 157°W, this permanently shadowed crater, about 5 miles (8 kilometers) in diameter, lies on the floor of the larger, more degraded crater Rozhdestvensky (110 miles, or 177 kilometers in diameter). With no sunlight to warm the crater floor and walls, ice brought to the Moon by comets or formed through interactions with the solar wind could potentially collect here."
