Q: How Humanity’s Next Moon Explorers Could Live In Lunar ‘Pits’

 Just look at that new video from NASA showing the first moon landing site in three dimensions. It’s tempting to touch on the surface nearby the Eagle lander there in the center and do some prospecting. 
  
 You’ll notice a lot of craters in that video, which is based on Lunar Reconnaissance Orbiter data. Across the moon’s surface, a separate study saw the spacecraft investigate 200 extremely steep-walled craters, known as “pits”. 
  
 These would be fascinating places to send astronauts for scientific study. Not only that, they’re actually one of the safest spots possible on the moon, according to a new study. 
  
 “Pits would be useful in a support role for human activity on the lunar surface,” stated lead researcher Robert Wagner of Arizona State University. 
  
 “A habitat placed in a pit — ideally several dozen meters back under an overhang — would provide a very safe location for astronauts: no radiation, no micrometeorites, possibly very little dust, and no wild day-night temperature swings.” 
  
 And if you look at the picture below, you can see at least one of those pits is in the Sea of Tranquility — the approximate landing area where Apollo 11 touched down 45 years ago this week. The pits were found mainly using a computer algorithm that scanned LRO photos, although a few of the craters were previously identified with the Japanese Kaguya spacecraft. 
  
 Large craters or lunar “seas” (ancient, solidified lava flows) are the locations where most of these pits are found. How they were formed is being investigated, but there are some hypotheses. Perhaps a meteorite impact caused a collapse, or perhaps molten rock flows under the surface gradually lost their lava, leaving voids. 
  
 To learn more, the researchers say more LRO images would be great (only 40% of the surface imaged had the appropriate lighting conditions for this study) and in the future, we’d need to get much closer-up than pictures taken from orbit. 
  
 “The ideal follow-up, of course, would be to drop probes into one or two of these pits, and get a really good look at what’s down there,” added Wagner. 
  
 “Pits, by their nature, cannot be explored very well from orbit — the lower walls and any floor-level caves simply cannot be seen from a good angle. Even a few pictures from ground-level would answer a lot of the outstanding questions about the nature of the voids that the pits collapsed into. We’re currently in the very early design phases of a mission concept to do exactly this, exploring one of the largest mare pits.”

 If scores of cartoons and ancient cave drawings are to be trusted, caves were mankind's first shelter on Earth. How appropriate, then, that NASA thinks caves could play the same role on the moon. 
  
 NASA says that the moon has as many as 200 "lunar pits," which aren't exactly craters—they're probably not formed by asteroid or meteor impacts. More likely, they are formed when part of the moon collapses over a void or a cave. Most importantly, many of them probably widen underground, opening up to form large underground caves, where astronauts (or future moon dwellers) could probably live. 
  
 "Pits would be useful in a support role for human activity on the lunar surface," Robert Wagner, an Arizona State University researcher who discovered the holes, said in a statement. "A habitat placed in a pit—ideally several dozen meters back under an overhang—would provide a very safe location for astronauts: no radiation, no micrometeorites, possibly very little dust, and no wild day-night temperature swings." 
  
 So, that sounds pretty ideal, and would probably be a nice stepping stone before we have full-on lunar colonies on the moon's surface. 
  
 The pits were discovered by NASA's Lunar Reconnaissance Orbiter and were detected by an algorithm that Wagner wrote, which automatically scanned the orbiter's high definition images of the moon's surface. 
  
 NASA believes the caves were probably formed by ancient lava streams hollowing out large swaths of underground channels under the moon, which eventually hardened as the lava cooled. It's essentially the same process that creates "lava tubes" on Earth, but there's little way of knowing if it's the same process without actually sampling them.

 That brings us to the question—what now? The next step, Wagner says, is trying to drop a probe into them. If that goes well, maybe we'll be able to set up lunar bases underground someday. 
  
 "The ideal follow-up, of course, would be to drop probes into one or two of these pits, and get a really good look at what's down there," Wagner said. "Pits, by their nature, cannot be explored very well from orbit." |||||
A: 
If humans ever set up camp on the moon, NASA thinks they can make great use of some natural shelter: moon caves. As Vice explains, the space agency has identified more than 200 lunar pits on the moon's surface, and those pits lead to caves below that range anywhere from 5 yards to 1,000 yards in diameter. It's not entirely clear how the caves formed, but NASA floats one hypothesis: Ancient lava flows created voids beneath the surface, and then nearby meteor strikes caused the roofs to cave in. "Pits would be useful in a support role for human activity on the lunar surface," says Arizona State University's Robert Wagner, whose photo-scanning algorithm identified most of them, notes Universe Today. "A habitat placed in a pit—ideally several dozen meters back under an overhang—would provide a very safe location for astronauts: no radiation, no micrometeorites, possibly very little dust, and no wild day-night temperature swings." The next step is to drop a probe into one of holes to look around. Bonus: The research could shed light on how surface patterns such as the "man on the moon" formed.
