NASA Plans To Build Houses On the Moon By 2040 (forbes.com.au) 100

Several scientists from NASA told the New York Times that the agency is planning to build houses on the moon by 2040. Forbes reports: The agency is set to return to the moon and is hoping its astronauts can stay long-term -- in a house built on the moon via a 3D printer. The idea is to build the house structure out of a special lunar concrete from the moon's surface, and NASA has found just the company to do it: Austin-based 3D printing company, ICON. In what's been dubbed Project Olympus, ICON

ICON created its first 350-square-foot prototype home in Austin in March 2018 with a proprietary machine called Vulcan. This year, it showcased its first model home at Wolf Ranch in Georgetown, Texas, which is part of its 3D-printed 100-home community project. The start-up first received funding from NASA in 2020, and in 2022 it announced an additional $60 million for a space-based construction system that can be used beyond earth. The idea is to send a 3D printer up to the moon via a rocket, and the printer completes its job from there.
"We've got all the right people together at the right time with a common goal, which is why I think we'll get there," NASA's director of technology maturation, Niki Werkheiser told The New York Times. "Everyone is ready to take this step together, so if we get our core capabilities developed, there's no reason it's not possible."

    NASA doesn't believe in reusable rockets. Instead, they are blowing billions on Artemis/SLS which uses ben franklins as fuel. And that cash is forced not out a rocket nozzle but an actual toilet. I've seen it myself, I was more surprised about it than you.

      What are you talking about? SLS isn't a NASA program, it's a congressional pork program NASA is forced to administer and dump much of their funding into.

      NASA meanwhile has been investing as heavily in reusable rockets as they can get away with without the Administrator getting fired. Which wasn't much at first, but SpaceX wouldn't exist without them.

    • Literally nobody who's paid attention to the US space program since the Shuttle was surprised at all.

    • They count on SpaceX with its StarShip, which can lift more cargo as SLS. And Blue Origin will also have bigger rockets in the near future.
  • Radiation is pretty high on the surface so better to hide underground.

    • How bad can the radiation be? Buzz Aldrin was outside the Earth's atmosphere for like 8 days (mostly within the capsule) and he's still kicking. How many of the Apollo astronauts got cancer? I think most of them lived well into their 80s or 90s.

        Its the gravity that will doom you. Long-term stays on the moon would be less than 6 mos before your cardiovascular system, ligaments and tendons started to weaken due to the 1/6th level of resistance. Bones also decalcify without the peziolelectric stimulation in the legs that trigger calcium layers. Its questionable if 1/3rd grav on mars is enough to allow return trips. Staying on Luna too long will turn into a 1-way trip. The Moon is a Harsh Cold Mistress is a good read that touches on some of these problems.
        • In an improvement from the ISS, at least on the moon the astronauts won't have to worry about shaking the moon apart whilst using their micro-gravity exercise machines...
        • That's pure speculation.

          At present we only have data for 1g and 0g. We have absolutely no idea how intermediate levels of gravity will affect people. Will 14% gravity do 86% of the damage of 0g? 99%? 1%? Right now we don't have any idea, because we really don't understand the biochemical mechanisms behind the problems

            Not give up, because centrifuges can handle it. But they might need to be pretty large. Which would mean not this decade.

            • In theory, yes. Unfortunately in practice building and maintaining huge pressurized centrifuges on the surface of a planet is going to be insanely expensive. You think housing costs are bad on Earth?

              That might still be viable for research or industrial outposts, but is going to put a huge damper on colonization - AKA people migrating with the plan that they and their descendants will live there in perpetuity.

              I suspect that if they prove necessary, would-be colonists will instead opt for much cheaper giant

        • Its the gravity that will doom you.

          Technically it's not gravity - astronauts in low earth orbit where gravity is almost identical to that on the surface of Earth suffer the same effect. What you need is a reaction force acting on your body and simulating things like this is how we have had astronauts survive for periods well over a year [wikipedia.org] and still return successfully to Earth afterwards.

        • And if that doesn't do it the sheer boredom of being trapped in a small, sub-like, building existence might drive you mad. Maybe you'll have people snap t each other like they sometimes do in Antarctic bases. Then there is the need to take care of any medical emergencies on your own.

        The Apollo astronauts literally reported seeing the flashes of cosmic rays hitting their retinas.

        Only being in a hazardous environment for 8 days is kinda not the same thing as being in that environment for 8 weeks, 8 months, 8 years, or 80 years.

        1) The Apollo capsules had some aluminum shielding. It turns out the shielding was not great in hindsight. 2) 8 days is much less exposure than weeks, months, years that people will live in homes. That's like asking how bad can be outside exposed to the elements (for 8 days) be? Short term exposure is not the problem.

          Plus, the normal chances of getting cancer are very low. Even with the chances being multiplied by a factor of 10 for the astronauts, it still isn't very large. And we're talking about a very small sample of very extraordinary people (physically).

          If you have 10,000 astronauts, you might see the uptick in cancer rates. With a dozen? Not likely.

      • by HiThere ( 15173 )

        The radiation level varies a lot. And the trip home from the moon takes long enough that you can't just evacuate. So good shielding is necessary. Whether you can do it with a 3-d printed "house", I don't know. There's no reason why not in principle...but it sure wouldn't be something light. (Not unless you carried your own building materials along. Plastics have lots of light elements, and they tend to be what you need. A nice dense hydrocarbon would make a pretty good shield, largely because of all

      • 8 days is peanuts compared to how long people will stay in those moonbases.
    • by Rei ( 128717 )

      Hypothetically. But given that we've never even sent a probe to even near a lunar lava tube, the TRL is quite low. There's also the issue of access to the surface being key for (A) solar power (if not using nuclear), and (B) all person and goods transfer in and out of the tube.

      I'm all for studying lunar lava tubes better! But it's a bit early to start calling them great habitats without knowing what they're like and what tech would be needed to make them livable.

      • Well, China is busy hunting for lava tubes with surface-level access to give it a shot. Having to use "skylights" would be a much more challenging proposition, though simply fully collapsing a section of roof and backfilling a ramp to the surface might be an adequate solution if the tube is small enough. Though you still have the fragility and limited shielding of a surface-level roof to consider.

            Not if we can avoid it - hence the search for walk-in tunnel openings that likely lead to deeper tunnels that will also be more stable and offer more shielding.

            But if we have to - a skylight severely compromises the structural integrity of an arch, and as such they tend to span the entire width of the tunnel, resulting in two independent tunnels leading away from a sinkhole - if collapsing one of them compromises the other, you probably didn't want to build there anyway. And importantly, breaking things (a

        • If you want to know what it's likely to be like inside a lava tube, go to Hawai'i; they've got lots of them. Most of them are old, of course, but some are fairly new. The new ones can tell you what to expect when you first enter the tubes. The old ones can give you an idea of how much you can smooth the sides and level the floor before you add any coating to them. And, if you go far enough up the old ones, you can get an idea what they were probably like when they formed. Lots of good data to help you

            I live in Iceland, I know what Earth lava tubes are like :)

            No two are the same, and lava tubes on the Moon are not expected to be like those on Earth.

            • If nothing else, you can at least get a general idea about how rough the inside will probably be, how sharp (much more important when you have to protect your space suit than when you're working in a shirt sleeves environment) and how hard they are. And, thanks, I'd not thought of Iceland, but knew about Hawai'i because been there and seen them.
              • by Rei ( 128717 )

                You really can't. Gravity is different (flow rates / scales), lavas are different (indeed the light areas are mainly anorthosite), there's no atmosphere for subsequent oxidation (fresh lava is much sharper than old), outgassing is probably much more vigorous, and cooling is only radiative, for starters.

                You cannot just make assumptions with space exploration - you have to actually investigate and try things out. Even in the huge rush of the lunar space race both the US and USSR launched a significant series

              • To second Rei's comment - lava tubes are all different. They've got a national park in California I visited as a child - dozens of tubes mildly developed with paths and approved for public exploration, and countless miles more that you can explore at your own risk.

                And every single one of them different - within the span of a few blocks, sometimes even within the same tunnel and its branches, you'll see everything from sections as smooth as flowstone, to covered in razor sharp spikes or edges, and everythin

        Sorry, but if you don't know the environment, you can't estimate the technology readiness level. That we need to know more about the environment is clear, what or readiness level is, isn't. (At 70 degrees we may already have several self-sealing envelopes that would work. I have a question as to whether they could be repurposed for a vacuum on the outside, but having a question isn't an answer. Someone will know.)

    Considering how denialism, shortsightedness in planning and advancement of personal interest within the political machines have been put ahead of meaningful admission of repeated ecological neglects comparable to the The Dust Bowl, preparation comparable to the Netherland's policy for defense of coastline and flooding (spectacular recent example in New York) and removal of corruption within a political party "because the other side are WORSE" I think there's going to be a pattern of crisis-to-crisis reaction spending that's going to see a loss of support within the public for spending money in space.

    This is even with the money printer going BRRRRR.

      To be entirely cynical... two things in the US have historically pushed space exploration - propaganda and pork barrelling.

      This leads to both parties wanting to spend money but not in a terribly efficient way that produces optimal science progression. And then both parties can argue about the waste and each can say it's the other's fault.

      But in the end, some damn spectacular stuff gets done.

      Now, however, there's a third motive starting to pop up - power. First there's territorial control, second comes profit. A manned presence on the Moon means you control territory on the Moon in a very real way. Controlling territory on the Moon means, if you're able to do any effective in-situ resource utilization, you have better access to space-based resources than those who don't have territory there.

      I'm not convinced we're there yet, LEO is still better for pretty much everything and anything that might interest a politician, but maybe the politicians believe that's changing and they're competing for the high ground.

      • Space development is also beginning to leave the domain of political funding, which I suspect will be what really saves it.

        The asteroid belt promises a gold rush to dwarf anything ever seen on Earth - with gold actually being one of the less valuable treasures to bring home, and at over $50M/ton even that will be *incredibly* profitable to ship back for the foreseeable future.

        And the moon is both a short-term testing ground for the needed technologies, and a long-term source of pre-made industrial equipment

  • The NYTimes article [nytimes.com] also discusses the development of a high-strength, high-temperature concrete made largely from lunar regolith. This would be used for creating landing/launch pads. These will definitely be needed, because kicking up a cloud of lunar dust with every rocket is not a great idea for the long-term reliability of a base or rockets.
    • Certainly not great, but it remains to be seen how big a problem it really is.

      After all, most of the dust from a rocket launch will be moving fast enough to be scattered across the entire surface of the moon, while the dust from earth-moving equipment will mostly land right back on your equipment and habitat.

      If we've got hundreds of flight a day it'll likely start to be a problem, but that's LONG term.

Ironically, the existence of a base makes this a bad idea since you're taking unnecessary risks whereas the Apollo program had to
