Why no wheel?

Why no wheel?

Postby spacemonkey » Wed Dec 06, 2017 12:33 pm

Way back when I was a kid, all the science fiction books had the space station looking like a big bicycle wheel and rotating slowly to create artificial gravity. Needless to say its not how it turned out. Why not, did it make everyone puke or what? Just curious.

And it would actually need to rotate pretty quickly unless it was very large:

it would need to be a few football lengths in diameter in order for it to rotate comfortably at 1g. which, for what we've put up in space, is massive.

i think it's conceivable still now though, especially if we ramp up space mining, and 3d metal printing machines. if we can do the work in space that saves all the cost of lifting which is the main reason why we haven't created this. if someone wants to make a space station that is used as a terminal from LEO to the rest of the solar system, they probably will be making a spinning station. tourists/business travelers to the moon or whatever would do better with some amount of gravity.

i know in spacelab they ran circles around a module to show the premise worked, which is probably why all the scifi stories from that age had it as a common theme

So the rumours that your girlfriend generates her own gravity is true!

If her mass was sufficient, she actually would, may even have moons too. :-B
