Our moon with atmosphere?

Maybe it would be simpler to just give them very heavy suits to wear? Wouldn't do anything in orbital micro-gravity, but on the moon's surface it should mimic earth's gravity pretty easily, I'd think.

Where would they get them? From Earth? Make them on the spot?

They demonstrated human powered centrifuges that would probably do the job. One person pedals and another balances out while "just along for the ride". The study suggested that the passenger would actually get more benefit than the "power source."

Apparently though, the spinning motion has an effect on the semi-circular canal balance organs in the ear, causing nausea. Maybe not for quick trials like that, but for long-term experience.

But if the diameter is more than 200 metres, or something similar, people don't get sick.
Maybe with the lower gravity on the Moon, it would be practical to build a giant merry-go-round that people could sleep on, or live on when they weren't working. 200 metres is a bit big though.

Of course, they might find medical ways to combat the sickness. I wouldn't be surprised if they were working on that problem right now, in some NASA lab.

I'd assume at least the first ones would be shipped up, or at least the components for making them. I doubt it'd be worth builing a factory on the moon just for making weighted suits.

It cost ten thousand dollars to put a gallon of water into space.

Well, they should probably use something else, then.

A case of Rocking Rock beer, then?

The wikipedia page on artificial gravity is quite good. It's 224 m RADIUS that would give 1g at 2 rpm.
2 rpm is the limit for most people before they start experiencing nausea.

I thought it was diameter, not radius. That's a big space station. But not impossible.
And anyway, smaller ones might be good enough, with other techniques combined.

With a station that large you could have the hub "stationary" and the rim rotating. That way arriving ships wouldn't have to corkscrew in.

224m radius @ 2rpm...That rim is going to be moving at a pretty good clip. But I can already think of ways of transferring people and materials on/off it without having to stop its rotation, tho. Not a difficult engineering challenge, I think.

No, not at all. You just make the ship that is docking spin at 2 rpm, and then unload at the centre of the station, where the cargo would be effectively weightless.
Then, as things are moved out towards the outer rim, computers would have to move counter-weights about, to keep everything in perfect balance.

[FBM]

Ah. Yeah, that could work, too, but I was keying off Zilla's idea about a stationary hub with rotating rim.

[Gawdzilla Sama]

They would send cargo down two opposite "spokes" at the same time. If the weight difference is within tolerance they would balance each other out. Eight spokes would mean four pairs of elevators, one for humans, three for cargo or humans.

Question- If you were on the inside wall of a collossal rotating cylinder and fired an arrow straight up (that is, through or toward the rotational axis) where would it come down?....Where it was fired from?...Or does it depend how 'high' it were fired?

[Audley Strange]

Can't we just sheath the moon inside a large balloon and then inflate it with gasses?
