NASA Found More Water On the Moon —But Don’t Plan On Having a Sip Any Time Soon

The permanently shadowed craters at the moon’s south pole are both the first and last place lunar astronauts would want to spend their time. The appeal is that they have generous deposits of water ice, a critical resource for any potential lunar base (ice means drinking water, yes, but it also means oxygen that can be used for synthesizing atmosphere and hydrogen for rocket fuel). But then there’s that business of the permanent shadows. It gets awfully cold on an airless body if there’s no sunlight—about -250º C (-418º F), in this case—and working in permanent darkness is no easy business, either. It would be a lot handier if there were significant amounts of water on what amounts to the more temperate parts of the moon: the near and far sides where any one spot is brilliantly lit for two full weeks out of every month. Well, good news: NASA announced today that it has discovered water in just such a site: Clavius Crater, located between 50 and 75 degrees latitude in the southern lunar hemisphere on the near side of the moon. “Water is extremely critical for deep space exploration,” said Jacob Bleacher, NASA’s chief scientist for human exploration and operations, at a Monday press conference. “We know that it exists in some of the darkest and coldest craters, so finding it in places that are easier to reach is very helpful for future exploration.” The new discovery was made by the Stratospheric Observatory ...
