AI Thread Summary
The discussion centers on a proposed concept called The Space Tent for Martian towns, which suggests using a giant inflatable dome made from super-strong plastic instead of traditional glass structures. The design aims to protect against asteroid impacts, with an inner layer that can stretch upon impact and an outer layer to prevent piercing from smaller debris. Concerns are raised about the structural integrity of glass domes, particularly regarding their weight and susceptibility to breaking. The conversation also touches on the need for easy repair methods, potentially utilizing self-sealing materials or nanotechnology. Overall, the Space Tent concept emphasizes practicality and safety for Martian habitation.

Hey we've all seen those movies and documentaries where civilization has buil giant glass domes on The Moon or oher planets. I say this is structurally unsound. It's going to break or atleast crack. I divised an idea called The Space Tent. We take a giant plastic bag the size of our martian township. We inflate it so it is a giant dome. It's infalted high so large car sized asteroids and objects will bounce off. It's smaller ones that I think are going to be the problem.

My Physics tells me that if we make it out off a superstrong form of plastic it may work. 2 actually. 1 innnerlayer that can stretch lik a garbage bag when large objects hit it. And then an outerlayer of tough tight plastic that will stop small sharp slow objects from peircing it. The logic is hat large object would be slown down and just roll off. Light objects would just bounce off. Least the fast one. The slow ones might get stuck on he plastic.

Then there's of course the issue of how do we repair it when there's a hole. I hink this beter than glass cause it would certainly break on contact. We'd have to make giant pillar cause glass is heavy. It would also be a lot more expensive. It may work cause they use this on this space station I believe. I wouldn't use it on The Moon cause there's no atmosphere to stop really large asteroids.

Why do you assume they are glass? Surely if we have a super strong plastic, strong enough that we can inflate to do the job and protect us inside, it would make sense to make thicker (more solid) layers and create panels in the shape of a dome. Giving you better structure and rigidity. Plus, far more protection. Kevlar body armour style.
 
Do you have any clue how fast asteroids hit the moon? Nothing we can make will cause them to 'bounce off'. You need to learn a lot more about physics and engineering...
 
That's why I sai I wouldn't make it on The Moon. It has no atmosphere. This would be for Mars and thick atmosphered planets. Besides hey use an airbag on The Space Station.

You've seen the craters on Mars right? And you know the atmospheric build up of the planet?
 
Yes Mars is 1/3 the size of Earth/ I know he atmosphere is far thinner but it could deflect and bun small asteroids. Besides if any asteroid large enough to make huge craes hit our colony it wouldn't matte if the cover was made of glass or plastic.

...or several feet of steel reinforced concrete, for that matter. So the dome doesn't have to be made to withstand such things.

Why not just make it from a material easy to patch (or even self-sealing?)?
 
With nanotechnology doesn't someone have selfrepairing plastic?
