When On the Moon and Mars, Move Underground 294

astroengine writes "Recent observations of the lunar and martian surface are turning up multiple discoveries of 'skylights' — collapsed roofs of hollow rilles or lava tubes. These holes into ready-made underground bunkers could provide ideal shelter for future manned bases on the two worlds. Firstly, they would provide shelter from the barrage of micrometeorites, solar x-rays and deep space cosmic rays. Secondly, they'd help protect our burgeoning colonists from the extreme swings in surface temperature (on the moon, temperatures vary by 500 degrees F, but inside these lava tubes, the environment remains at a fairly constant -35 degrees). Thirdly, the sci-fi notion of underground space cities could become a reality."

    it's not obvious to me how you can have a habitat in space without being underground.

    I guess you could just build thick-walled structures of some sort, but going underground seems like it's probably slightly easier.

        Would it not be an option to send robotic construction workers to the site ahead of time to begin construction of the shelter? Or, send two separate ships, one that just has cargo on board? That way, the ship that carries the people would need to carry less, and therefor the weight that would be allocated to kit could be allocated to slightly thicker walls.

            Forcing everyone into the hot tub during a solar flare is actually not as impractical as some might think.

            There was a situation like that depicted on Defying Gravity [wikipedia.org], episode 8, "Love, Honor, Obey" where during a solar flare the crew took refuge in a room surrounded by the water tanks and polyurethane insulation.

              Also, it would be a good idea to mention "BBC Space Odyssey: Voyage to the Planets" (avoid the castrated US version), which is monumentally better (why, why do I even compare them?) and of which "defying gravity" is a direct rip-off, just made extremelly poorly.

                Sorry to offend. I haven't seen "Voyage to the Planets" (UK or US versions). The Wikipedia page describes a different motivation for their voyage than on Defying Gravity - the latter was more about inter-personal relationships (unfortunately described as Grey's Anatomy in space) and the alien objects on the various planets.

                I actually liked the show. I don't understand people's vitriol against the various science liberties employed, like instant communication over distance or the artificial gravity, as many (most?) other popular Sci-Fi shows do the same (Star Trek, Firefly, Stargate, etc... - Don't get me started in SG-U.) In addition, the production quality (CG, music, etc) was very high for a weekly show. The half-mile long ship itself was designed with input from NASA and consideration of possible advancements and launch capabilities over the next 40 years.

                Before passing complete judgment on DG, I would recommend watching all 13 episodes, not just the 8 aired. Perhaps I'm biased toward some of the character relationships and interactions as they reminded me of things in my own relationships and things I felt when my wife died of a brain tumor in 2006. I know the last scene of the last episode, Kiss, though sappy, was like my last kiss with my wife, except she didn't wake up afterward. I heard her last breath, felt her last heartbeat and kissed her goodbye.

                There's more to good sci-fi than the science.

                  I disagree.

                  If a show/movie is depicting technology close to our own, then it should be consistent in that portrayal, and not show technology that is hundreds of years away or more.

                  What would you think of a TV show set 5 years in the future, but which shows cops carrying portable laser guns, while everything else is exactly the same? It'd be stupid, and everyone would say so. Several leaps in technology would be required to have handheld laser guns, the biggest of which would probably be batteries capable of storing far more energy than today's. If that did happen, many other things would change because of it; electric cars would become popular very very quickly, for instance.

                  Or how about a show set 10 years in the future, where everything's mostly the same, people still drive cars, but instead of taking planes to faraway locations, they use teleporters? Again, stupid.

                  It's the same deal with artificial gravity and FTL communications. The only difference is that they aren't quite as obvious to science-ignorant audiences as ray guns and teleporters. Artificial gravity and FTL communications might indeed be possible (we'll never know until we achieve them, as you can't prove a negative), but if technology evolves to the point where these technologies (particularly artificial gravity) are possible, then we'll also have much better propulsion technology, and many other things would be different.

                  These things work in Star Trek and Stargate because 1) in Star Trek, they're portraying a society far more advanced than ours, not only in time but in technology (partly because of contact with technologically-superior races like the Vulcans), so they have a lot of leeway in making up possible new technologies, and 2) in Stargate, even though it's set in present-day, it posits contact with races with much older civilizations and FAR more advanced than ours (especially the Asgard) with technologies we can currently only dream of, so again they have lots of leeway in making up stuff that's well beyond our current understanding of physics. Notice than in both these series, FTL propulsion is commonplace. Anyone advanced enough to have FTL propulsion will probably also have figured out artificial gravity along the way. Firefly is slightly less defensible because they don't have FTL propulsion, but they are hundreds (maybe thousands) of years in the future and have apparently figured out how to travel to another star system, as well as terraform many planets and moons, both things that are well beyond our technology, and their propulsion, while sub-FTL, is still far more advanced than our primitive chemical rockets.

                  If you want to see near-term space exploration shown realistically, rent a copy of 2001: A Space Odyssey. Made way back in the late 60s, they got just about everything right: NO artificial gravity except by rotation, long communications delays, etc. The only things they got wrong were 1) the timeframe was way too optimistic (it's 9 years past 2001 and we're still nowhere near long-term manned missions, large rotating space stations, or moon bases; we slacked off starting in the 70s and we're getting lazier), and 2) the intelligence of the HAL9000 computer.

                  If they could depict all these things correctly in a movie made back in the 60s, before inexpensive CGI existed, there's simply no excuse for any movie or TV show to screw up future technology now.

            • Red Mars did it.

          • On the other hand, occasionally you have an extremely lightweight payload of human beings. Send them at very high acceleration on a much faster hyperbolic (far above escape velocity) transfer orbit.

            Is it really feasible to send humans faster than Hohmann with current tech? Last I heard it wasn't... which makes radiation (and perhaps worse, isolation!) a legit problem.

            Similarly I was under the impression that it wasn't necessarily attenuation from atmospheric mass that provided cosmic radiation shielding, but rather the magnetosphere, which is something not easily duplicatable on an interplanetary craft.

              The atmosphere stops the cosmic rays, which are far too energetic to be bothered by the magnetic field. The latter stops the solar wind which would otherwise erode the atmosphere, though it would stop them quite readily while it lasted.

        Conditions on the moon would actually be pretty unenviable for heavy machinery. The low gravity would be a plus, allowing impressive feats of strength, and otherwise implausibly spindly construction(though remember that mass, and inertia, don't change. That one can be embarrassing). It's all downhill from there, though.

        The lunar surface experiences no weathering, only meteorite and micrometerorite impacts, so it consists largely of fused globs and shards of glassy materials, as sharp as they day they formed. Without an atmosphere, static cling is a serious issue. Without much water(or the temperature envelope in which to use it) you can't just hose that stuff off. It worms its way into every crevice, and just grinds away. If you generate heat, conduction and convection work substantially less well than you would expect, since there is no atmosphere. The rock still conducts heat away from the work area; but any air-cooled machinery isn't exactly going to work very well...

        I doubt that it is impossible; but it is a nasty pile of engineering challenges. Something like Mars, which is basically a desert that used to beat up and steal the lunch money of even the toughest earthly deserts might actually be much easier(despite being further away). They have actual weathering there, an atmosphere(albeit a rather thin one) for air-cooling, and a surface that isn't exclusively made of tiny shards of glass that just want to cling to you and grind away....

      If you're expressing some sort of sentiment about leaving the moon or mars dead and barren and pristine environments then I'm very much

      The lack of an atmosphere, lack of gravity to sustain one, and lack of naturally occurring liquid water means the moon more or less totally lacks much of the negative changes we could induce by colonization. Air pollution doesn't do much for you when you don't have any air to pollute. There's no water cycle to carry waste where you don't want it. The outside environment (aka hard vacuum and or regolith) is already lethal/abrasive, good luck making it 'worse' by polluting it.

      About all you'll get is the 'desp

    It all boils down to a system of tubes?

    Space colonists will be selected from a population conditioned to survive underground for extended periods.

    I would highly recommend Kim Stanley Robinson's Mars trilogy. It's great science fiction and he piles on the science. In his novels some colonists actually live in lava tubes on Mars. I never get tired of reading those 3 books.

    "the sci-fi notion of underground space cities could become a reality."

    Because the stuff I've read clearly calls for moon settlements to have transparent glass domes.

    • transparent glass domes don't do well when meteorites hit them. With no atmosphere there will be regularly occuring meteorites.

    "Thirdly, the sci-fi notion of underground space cities could become a reality.""

    Well, duh. Shockingly enough, many 'sci-fi' writers are fairly smart people who know what they're talking about. Underground space cities aren't usually ideas authors just pulled out of their asses because they though it'd be cool. Mostly they show up because the authors sat down and thought 'hmm, well, if there was _really_ a settlement on a rock with no atmosphere and very little gravity and we wanted to deal with the problems of extreme temperature variations and exposure to radiation and so forth, I wonder what would be a good idea...oh, hey, underground cities!"

    It tends to bug me when stories like this get written from a viewpoint (often subconscious) of 'hey, those crazy science fiction writers thought about this fifty years ago, but now someone with letters behind their name wrote about it in a Serious Publication, that makes the thought Real!'

    So you want your underground Moon colony, but having a hard time getting funding for the project? No problem. Just spin to them as an ultra secure penal facility.

    The politicians can now say the public is safe because the prisoners have no way of getting back home. The prison industry will love it. All that extra cash flow and stuff. The scientific community at large will now have a reason to turn a blind eye. And if they die in the vacuum of space, no one will care.

    When you send mankind into space, expect all of it's demons that make up Humanity to follow right behind.

    "...ready-made underground bunkers could provide ideal shelter..."

    said ideal shelters detected by collapsed roofs.

    Exogeologist: "Look at that collapsed cave! We could live in there."
    Pilot: "Sure, you go in first perfesser."

    This beats the astronauts' old "built by the lowest bidder" grumbles all to hell.
