We're closer than ever to fulfilling our destiny as the moon's mole people.
According to a recently published report in Geophysical Research Letters, scientists believe they've confirmed the presence of naturally occurring caverns that could "potentially serve as secure shelters for humans and instruments." These are lunar lava tubes, and their existence has long been suspected and hoped for. Now, by combing data from NASA and JAXA (Japan's equivalent space agency), we're more certain than ever that they exist -- and that we've found one.
Put simply: A lunar lava tube in the Marius Hills region is the best location for a lunar colony we've found yet.
The tubes would be ideal colony sites because, as you probably know, the moon lacks an atmosphere (the lovely space blanket that protects us from asteroids and the sun's rays). Without some kind of shelter, colonists and valuable equipment would be exposed to the unforgiving reality that is life off the planet and outside an atmosphere. The existence of these tubes would mean a ready-made shelter for colonists.
