If we're ever going to colonize another world, we can't rely solely on the supplies we bring with us. We'll have to make use of the resources available at our destination, with water being one of the most important. Not only can we drink it, but add a bit of science and voilà! You've got oxygen to breathe or rocket fuel to fly. Figuring out what resources are where is extremely important, and we've been honing this craft by looking at our celestial ally, the Moon. A study published last year suggested that water may exist in high quantities in the lunar interior, and now researchers have found evidence of water being distributed across the entire satellite, which is at odds with the widely held theory it's concentrated in the colder spots at the Moon's poles.
