Poloidal rotation or bust!

>>11786378
You just need two compartments attached with a tether that spin around a central axis.

>>11786378

The most important part is designing the structure so that the centrifugal loads are not transferred to the delicate atmosphere-bearing main structure, and especially not the spokes containing the elevators. This can probably be achieved by having tubes made of a 2 shell construction, with the inner shell retaining the atmosphere and the outer shell absorbing the loads, with a tubular truss structure separating the inner and outer shells.

For space stations a complete torus is the way to go, and for interplanetary spacecraft a semitorus & counterweight would be better.

>Poloidal rotation
please spoonfeed me I'm retarded and don't know what that is

>almost 60 years of crewed spaceflight
>not one space station with rotational gravity

Even a simple tether system that put out .2 g would be useful, what gives?

They need a place to film movies and TV in zero G, and a place for tourists to experience it.

Space stations need to be more than science outposts if anyone is going to live in one outside of rich fucks. A space hotel is probably the first real thing going up.

>>11786391

What?

>>11786535
for interplanetary, launch in pairs and do can on string

Musk isn't into space colonies. He's more of a planet colony kind of guy. Bezos is the space colony dude.

>Musk isn't into space colonies.
Irrelevant that he wants to retire on Mars. He's really the ride guy. Buy rides from him, do whatever you want in space. He's not going to say no to a 50 launch block purchase.

>>11786378
why

>>11788239

Because houses in space.

>>11788102
Bezos is going to try to become Degwin Zabi but he's going to fail

>>11788610
why

>>11788663

Because you touch yourself at night.

>>11788852
>>11788610
those are not good reasons.

>>11786535
What about flip and burn spaceships? Do we have the tech to provide constant acceleration?

>>11786378
O'Neill cylinders seem obviously impractical, as it would take a monumental effort to keep them spinning around the right axis. (any imbalance and the rotation would flip to an axis perpendicular to the intended one)

But, it could be used to make the night day cycles. Make it a torus, but not a balanced torus, but more like the spinning top, and with windows on one side and mirrors on the other. With the right amount of imbalance, it might be possible to make the station flip every 12 hours, creating a night/day cycle.

>>11788663
Because gravity on Mars: 0.38G
Atmosphere on Mars: 0,6% of Earths
Gravity and pressure in a spinny space house: anything you want within material limits

>>11788938
O'Neill colonies come in pairs for the purpose of aiming them at the sun. It's not insane to keep them spinning about the right axis.

>>11786924
Safety margins probably; any part needs to be modeled for failure scenarios. If at any point the parts with centrifugal force somehow separate from each other, and a crewed part could either be flung out into a possible collision with another spacecraft or worse, down into the atmosphere, I would think that would get a veto. It would be safer further away from the planet. I would expect manned geosync spy platforms in the future to have spin gravity at least for the hab modules.

>>11788958
why even bother with mars or space? And LEO? If it's big, you're gonna have to reboost it constantly.

>>11788938
O'Neill cylinders are meant to be in counter-rotating pairs you know. Gundam was wrong in that matter.

>>11788963
Why would you even consider LEO? Just park them in a lagrange point.

>>11788632
That's funny, I always saw him as irl Lex Luthor. Strange how much physical characteristics influence a character's perceived persona.

>>11786378
from what I heard objects would always fall sideways and your inner ear would not be able to adjust and you'd feel wonky and out of balance

>>11788979
There's something soft about Bezo's facial characteristics that keep me from seeing him as a Lex Luthor type. That's probably one of the things that has helped him slip under the radar of regulators for so long even though his business practices can be considered evil.

>>11789766
The larger the radius, the less that ends up being the case.

>>11789781
yeah but the cost of a large radius torus would be enormous, so it wouldn't work for a small station

>>11789809
A small module and counterweight with long enough cable is sufficient

>>11788911

no

>>11786378
put it in equatorial low orbit and you do not need significant radiation shielding, which would otherwise dominate the mass budget

>>11788911
Sadly no, we don’t live in The Expanse yet. Chemical rockets can only provide 1g for a few minutes, not weeks. It will take a massive breakthrough before we can manage this. The best we can do now is spin gravity.

>>11788911
You need compact fusion or antimatter for that, so no.

>>11786378

this kind of shit is not the kind of shit we launch, its the kind of shit we build somewhere in low/0 g

I posted in the dead thread.

>>11790155
But if we had it, there'd be no reason to use any other method, right?

>>11790439
It's wasteful. And what if you want to stay in one place?

>>11790161
