NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
If you don’t already know: Yes, there is water on the moon. NASA suggests there’s as much as 600 million metric tons of water ice there, which could someday help lunar colonists survive. It could even be turned into an affordable form of rocket fuel (you just have to split water into oxygen and hydrogen, and presto—you have propulsion for spaceflight).
