Re: Ring Habitat on Mars Doughnut Torus
surprise we are still in the same range for material mass whether its the 304L or the Austenitic High-Manganese Steel: roughly 1,000 tons for the same tubing dimensions

Re: Ring Habitat on Mars Doughnut Torus
SpaceNut,
Was there any mass reduction at all?

Re: Ring Habitat on Mars Doughnut Torus
There may have been a bit but not any thing that mattered.
I am going to think of another plan to build with the fabric, and regolith but targeting just 100 so that it can be repeated as many times as we need. Once its got air in it and not losing it we may be able to do counter pressure with more materials on the out side with more fabric and regolith. Interlocking the tiers for a finished shape.
I will create a new topic later

Re: Ring Habitat on Mars Doughnut Torus
SpaceNut,
Maybe we are better off using impermeable fabric and regolith bags only. There's no significant upper limit to the size of inflatable structures here on Earth.
Take note of the size of the human standing to the left of this structure:
Look at how tiny the cranes are next to this inflatable:
If we can pressurize and fill with regolith dust for structural support and radiation protection, then the habitat should still be there a century from now. That ought to provide sufficient time for Iron mining and smelting for steel construction.
