On a quest to locate water and other volatile minerals in the Moon’s soil, the LCROSS experiment—Lunar Crater Observation and Sensing Satellite—hurtled a spent Centaur rocket into a dark crater at the lunar South Pole last year. The crater, known as Cabeus, is one of the permanently shadowed regions of the Moon, and researchers believe it is also one of the coldest.

After six years of up-close observations, the Cassini space mission is painting the most detailed picture ever of Saturn and its complex ring system.
