Adding Spin Gravity on Small Worlds.

I am still a bit ill, (Not too bad), but have to limit contact with people so I guess I will do this:

Adding Spin Gravity Simulation On Small Worlds:  (This is the best article I have encountered for it, it is sort of about the Moon).
https://www.science20.com/robert_invent … how-176169

To their credit, Japan seems to have an interesting imagination on the topic of very grand instances of this notion, for the Moon, here is an example: https://www.gearrice.com/update/japan-w … %20gravity.

The Europeans seem to be contemplating a space station with a floor with a Centrifuge in it: https://www.impactlab.com/2023/05/05/gr … 0of%20four.

It is not made for the Moon, but I do wonder if with better bearings it could do something on the surface of the Moon.

Re: Adding Spin Gravity on Small Worlds.

For Void ....

First, best wishes for recovery from whatever you are dealing with ....

Second, best wishes for this interesting (to me for sure) new topic! 

While the topic will inevitably contain details that seem (or are) similar to those in topics about building rotating habitats from scratch, the scope of this topic seems equally likely to occur, and the kind of habitat this topic is about may actually have a GREATER chance of success, because all the materials to be used are already assembled by various natural forces.

I am hoping this new topic wins support by other members of the forum.

If there is someone ** out there ** who would like to contribute but is not currently a member, please see Recruiting Topic for procedure.

Re: Adding Spin Gravity on Small Worlds.

Thanks (th), I am actually going to link this to my other topic that I often post in, but I thought that the materials of the 1st post are already valuable as reference, so I thought I would give this its own topic.  "Index» Terraformation» Worlds, and World Engine type terraform stuff."

Perhaps others will add to it over time.

I believe that in the old days ~70's putting spin gravity onto the Moon was not though to be practical, but it appears that it might be done in limited ways.

This is already quite interesting: https://www.science20.com/robert_invent … how-176169

Artificial gravity only intermittently during the day.
Or we might need gravity only intermittently during the day for health. Here is a study that found that full gravity in a centrifuge for just one hour a day made a big difference to muscle loss in bed rest volunteers lying with head slightly lower than their feet to simulate zero g. Other studies come to similar conclusions. Other experiments use "dry immersion" to simulate zero g, where a volunteer is immersed in warm water with an elastic suit to keep them dry, which has similar physiological effects to head down bed rest, but the changes take effect more quickly.

I decided to query for this from the above paragraph: "Here is a study that found that full gravity in a centrifuge for just one hour a day made a big difference to muscle loss in bed rest volunteers lying with head slightly lower than their feet to simulate zero g."

Human Centrifuge Preserves Muscle at Zero-G
Preventing muscle loss in space is simple: Just spend an hour a day in a giant human centrifuge that’s spinning at 30 rotations per minute. And don’t lose your lunch. In the first human experiment looking at the effects of artificial gravity on muscle mass, researchers discovered that a force of 2.5 g’s applied to […]

So, that is very promising for adult humans to "Serve" a hitch on the Moon.   I am sure some will think military, but maybe also if you work in Antartica, you may often have to agree to some terms of how you will be there for a certain time period.

Artificial gravity will not make the Moon more military oriented, not more than may be so for NASA missions, I would think.

In post #2, (th) posted this:

I agree, and I feel that if we can come up with reasonable methods to bring more volatile materials to the Moon, it can perhaps really assist in human reach out into the solar system.

I have to wonder if something like Neuralink could modify what a humans inner ear does as per motion sickness.  In that case we would have a great deal more liberty in creating spin gravity.

Re: Adding Spin Gravity on Small Worlds.

I am very satisfied with this so far.  Lots of reason to think adult humans could be kept reasonably healthy on the Moon for extended periods of time.  Not proven but seeming like a good chance's situation.  At least the materials of posts #1-#5 so far, are encouraging for it.

Done.
