Team Zopherus from Rogers, Arkansas, is the second-place winner of Phase 3: Level 4 of NASA’s 3D-Printed Habitat Challenge. The team’s design includes using a moving printer that deploys rovers to retrieve local materials.
The competition for this stage challenged teams to use modeling software to create a full-scale habitat design. This level built upon an earlier stage that required 60 percent design completion; for this round, submissions were 100 percent complete.
Entries were scored on architectural layout, programming, efficient use of interior space, and the 3D-printing scalability and constructability of the habitat. Teams also prepared short videos providing insight into their design as well as miniature 3D-printed models that came apart to showcase the interior design. Points were also awarded for aesthetic representation and realism.
NASA’s 3D-Printed Habitat Challenge aims to further the progression of sustainable shelters that will someday occupy the Moon, Mars or beyond by pushing citizen inventors to develop new technologies capable of additively manufacturing a habitat using indigenous resources with, or without, recyclable materials.
The 3D-Printed Habitat Challenge is managed through a partnership with NASA’s Centennial Challenges Program and Bradley University. Bradley has partnered with sponsors Caterpillar, Bechtel and Brick & Mortar Ventures to administer the competition. NASA’s Centennial Challenges program is part of the agency’s Space Technology Mission Directorate, and is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

How is the lander/printer "sealed to the ground"? There doesn't seem to be an drilling of anchors or similar, what allows it to be pressurised enough to serve as an emergency shelter? Assuming (for illustration only) a 50 tonne lander mass and a 5m diameter, you would be limited to 0.1 atm pressure without additional anchoring.

@walperstyle 5 лет назад

The atmosphere on mars is extremely thin. So far it also seems to be a fairly stable planet (not crazy seismic activity). Buildings wouldn't need to be anchored down. Some places here on Earth have buildings that are a few thousand years old and made of woods or bricks.

@1FatLittleMonkey 5 лет назад

@@walperstyle Sorry, I wasn't clear. Because the air pressure on Mars is low, less than 1% of Earth's, any Earthlike pressure inside a structure will be creating outwards force on any it, including trying to push it off the ground. At 1atm of internal pressure (if it is intended to be used as an "emergency shelter" for crew), it will be producing an upwards component of 10 tonnes of force per square metre. A 50 tonne lander, 5m diameter, will break its seal with the ground at just 0.1 atm. Even using pure oxygen (which is risky) you need around twice that pressure. Anchors aren't necessary for earthquakes or wind, they are necessary to hold it against its own internal pressure.

@walperstyle 5 лет назад

its own internal pressure is only an issue in the event it has somewhere to go. I'd imagine it wouldn't be that hard to create something much like a suppressor (commonly known as a silencer by hollywood people who watch too many action movies. Insulation that disperses pressure. But yeah< I guess they didn't show that much detail in this. To be honest, it wouldn't that difficult to create a structure that acts much like Blow off Valve used in vehicles. Or at least a series of layers that works in such a manner. Otherwise, its own pressure isn't any different than being in a submarine.

@1FatLittleMonkey 5 лет назад

@@walperstyle Layers/etc are irrelevant. It's the overall pressure difference. In a 5m vehicle at 1atm, there's 200 tonnes-equivalent pressure trying to push it off the ground and just less than a tonne from Mars' atmosphere pushing down. It will rip itself off its foundation. (Or in this case, off of any seal they've sprayed on the ground.) You can't maintain a pressure difference between the inside and outside, if it is open to the ground, without anchoring it down against that pressure difference. It's just physics.

@walperstyle 5 лет назад

@@1FatLittleMonkey Layers are not irrelevant if you disperse pressure. It gives it an avenue to dissipate energy over time and area. I think we are not understanding each other, you seem to think its just dirt on the bottom.

I'll work FOR FREE, so long as you supply air and food. I'll build whatever you need me to and have plenty of experience turning wrenches and building electrical systems.

@christina5025 5 лет назад

I feel like this should have taken first place. I'm no scientist or engineer but I've heard Martian dust is an extreme pain, and of the top three habitats, this seems to be the only one to account for how to keep said dust out during construction...

@treylane5456 5 лет назад

Thanks, Christina! We thought the dust problem was extremely important to deal with. The martian atmosphere is cold enough and low enough pressure that it would also freeze and/or boil any water in traditional concrete before it would have a chance to set. Both of those processes would ruin printed concrete. I might be a bit biased, but I think we're on the same page ;-)

@1FatLittleMonkey 5 лет назад

@@treylane5456 Does the lander/printer have any ground anchors that weren't shown in the video? I can't see how you can pressurise it to any level that would allow water to remain liquid, or serve as an emergency shelter, without the pressure lifting it enough to break the ground-seal. Elsewhere in the thread I used an example of a 50 tonne lander with a 5m diameter: it would only take 0.1atm internal pressure to lift it off any ground-seal. At 1atm pressure, that same 5m lander would produce 200 tonnes-equivalent of upward force.

@logiconabstractions6596 5 лет назад

You also don't have regolith on the Moon. Maybe there's an equivalent mineral they could use, maybe not.

@adamsmith8538 5 лет назад

What about the fact that the martini dirt is toxic? How will u be able use it to build parts of the interior if the regolith is toxic and would be exposed to humans?

@treylane5456 5 лет назад

Completely valid point! Using the two print heads, you could coat every bit of exposed martian concrete with a thin layer of printed plastic, or some type of penetrating binder could be sprayed on that would seal the martian concrete. Another option would be to filter out/neutralize perchlorates during materials processing. While a serious issue, we felt it was solvable in a couple of different ways without altering the design. Your concern about toxic regolith is one of the reasons we placed the Z-series suits in an airlock. We wanted to provide a way to service the suits in an environment that could be decontaminated first.

@miamzd1 5 лет назад

A great start! Well planned, good functionality and scale ability. A lot more needs to be added on and scaled up.

@wakeupuk3860 5 лет назад

What an absolute joke and total naive ambition of such plans to send humans to Mars. First with the numbers planned plus weight and size of the ship, fuel requirements and realistic times could be well over a year there and longer back. For Earth and Mars alignment to give the shortest travel distance, might mean a year or more living there. Even with all this 3D technology it would mean several humans in close proximity for maybe three years and unlike astronauts circling earth for half a year with the knowledge if need be they could be back on earth with in a month. Yes there are projects for people to pretend by wearing pretend spacesuits and living in pods in deserts with others - to see the effect on humans coping living with each other. It is all false and wishful thinking as no way apart maybe from very senior Buddhist Monks can 'even' very intelligent, proven calm personalities, group harmony tested profiles astronauts being able to live in such proximity with out ending up killing each other. We as a race on the evolutionary scale when we consider the type of films, games, pursuits and interests where violence, sex, self abuse, egos etc are now the norm - really are still in our caves banging the rocks. Plus even if the pods made to house them are technological marvels than we are amazed at when we watch them are still no more than confined huts with nothing but 'red' dust, stones and dried mud ever where. No research is being done on not seeing the green grass or blue sky of earth for so long, not letting loose and getting drunk, finally getting away from those at work or at home who drive us mad. Also the need for sex, even if planned and profiled assigned couples is planned for, what about falling outs, jealousies or unplanned relationships. What happens if your planned partner after two months fancies another member of the group and you can hear them having sex in pod you live in. I only went through 6 days of a girl friend choosing to dump me on a holiday for a guy whose wife I certainly did not fancy, and I am sure if I had known I would have had to listen to them having sex and me none for two years, I expect I would have murdered them both. We as a race, are no way ready for space travel in both terms of our primitive and basic traits plus current technology to travel to space. It may well be that even if there is intelligent life out there, life as know it 'Jim' due to it's very makeup is bound to the planet it is created on. Also to be honest even loving SF, watching the man land on the moon (if we actually did) and following all the NASA flights I now at 66 years old and see in truth what a foul, violent, destructive and obnoxious race we mainly are - should NEVER be allowed to colonize space.

@totalermist 5 лет назад

@@Lindenlc10 >That is why The Boring Company is doing what it is doing in L.A. That's nonsense. First of all, Mars soil is nothing like the ground in the L.A. basin so any experience gained there is worth very little on Mars(aside from the basics, that is). Furthermore, the current state of drilling and boring on Mars is this: www.skyandtelescope.com/astronomy-news/mars-insight-drill-hits-snag/ And no, the Boring Company is not magically better than scientists and engineers from DLR and JPL - they'd face the same issues. Boring and drilling requires detailed knowledge of the ground you're digging through and no one has this knowledge yet. Building underground structures is always more expensive, complicated, and risky than building above ground. Expanding existing natural structures such as caves or lava tubes is a valid option, though. But again, no such structures have been found and mapped on Mars yet.

@tobifoong8025 5 лет назад

I agree that an automated Mars version of The Boring Machine would be on Mars ASAP. but the first Habitats will be the StarShips themselfs. Each Starship has enough space for 700 - 800 seated passengers. The first Mars Astronauts will be only about 10-12 people so there will be more than enough living space for those 12 people in the first 2 StarShips (ie twice the space of the ISS). I believe the 3rd batch of landings( 1: 2 cargo, 2: 2 cargo + 2 Crewed. ) will have the TBM drills and Habitats like Zophorus and whatever things they discover they need from mission batch 2: This 3rd batch will be 5 years after the fist landings. Ie close to 2030 at the earliest. 10-12 years from now we should have fairly good robotics.

@tobifoong8025 5 лет назад

@@totalermist You cant compare the Mars Insight kinetic impact drill tool with the Boring machine's rotary Drill bits based on decades of tunnel boring all over the world. TBM is thousands of times larger and thousands of times more powerful !! By the time the Boring Machine gets to Mars it will have had 10 years of new technology. In 5 years TBM will be automated robotic drilling machines. Now add 5 more years of adapting that to the Mars environment before they are launched. It will be much more advanced, almost like is "Magically" so.

@InfuriatedHawk 5 лет назад

Sharp edges and corners, like those found in a pyramid, create stress concentration that can prove catastrophic when you have large differences between internal air pressure and atmospheric pressure. With balloons, the natural tendency is to expand outward in a spheroid shape because the sphere is inherently the most stable shape. That's why air tanks and large aircraft fuselages are typically cylindrical and airplane windows are rounded.
