When traveling in space, why don't they place spinning sections on ships to create artifiial gravity?

Answer 1

Because it'd have to be very big to not cause nausea. If the radius is small and spinning, the force (or g's) experienced by your feet will be very different from that on your head, and you'll get nausea.

Answer 2

Good question! Much of the research being performed requires microgravity, and they're still experimenting on people. Since it is already known that "zero-G" harms bones, the immune system and even increases pathogenicity of common bacteria, it would seem to be about time to experiment with simulated gravity.
Why not use long tethers to separate components of the spacecraft? That would also be an asset if a nuclear power module was kept a good distance from the habitation module. Though there might be some stability problems with a flexible tether, surely they could be resolved by active damping and small ion engines to maintain separation.
Sorry I don't have an answer, but you ask a good question.

Answer 3

Only yutgoyun's answer is correct. A spinning centrifuge plays havoc with the semicircular canals in our ears, and causes nausea. This centrifuge idea was proposed back in the '40s and '50s, and was used in the film 2001: A Space Odyssey, both in the space station and the ship going to Jupiter, but that film was made _before_ anyone had really spent any time in space. After experience with SkyLab and Mir, it was realized that most humans do just fine in free fall, and actually prefer it. There's no reason to use centrifuges...their side effects (nausea) are worse than anything you get in free fall.

Answer 4

between the suggestions purposed for the bone mass loss assosiated with residing in a nil gravity ecosystem is such as that. The pill may be sent spinning so as that astronauts making the long journey to mars could make the trip without bone mass loss. So as a results of this my answer is for particular theoreticaly utilising centrifugal tension ought to paintings as a source of gravity.

Answer 5

A true space voyage would require a large provision of water.All systems will respond to the mass of water.It will be necessary to keep the water moving to prevent ice-up.Thus causing gravity if kept moving around the skin of a vessel.It is difficult to process water as ice in space.Makes me wonder if Aliens would trade something for our water.

Answer 6

in popular science they had an article that talked about a "heavenly Hilton" which would be a satalite where the rich could go to and they talked about how they would have it spin to create gravity and that they would have a stationary section for zero gravity (not really zero because the satalite would have a minute gravitational pull just like anything else with mass)

Answer 7

to create gravity equal to earth it would have to be spinning pretty fast, and plus it would just cost a lot more money to do that, and plus some of the experiments in space are for 0-Gravity environments.

Answer 8

The amount of energy to create a false gravity anywhere in space where gravity doesn't exist would take huge amounts of energy, even for a small space. It would also put a craft at risk to create this.

Answer 9

Right now, spacecraft are too small to have the complex mechanics to have some portions spinning and others remaining stationary. It's feasible, but costly, and we're not venturing beyond Earth orbit any time soon, so this means that flights aren't long enough to merit the extra expense.

A trip to Mars might incorporate such measures.

Answer 10

that was how they had artificial gravity on the space station in the movie, 2001.

So far, we have only traveled to the moon.
i am guessing that the trip is not long enough
to make the expense worth it. it would be an expensive design element.
