Artificial Gravity

[gyro]

Arthur C. Clark wrote about this way back , he also suggested geosyncro-orbits years before the fact, so is it feasible.
We have machines to create 'G-forces' on Earth, could this technology be adapted to work in space. The space station would be the place to try it out.
NASA are already thinking forward to inter-planetary travel, but even a round trip to Mars is 12 t0 18 months with considerable health problems due to weightlessness.
If a artificial gravity crew compartment/module were assembled in earth orbit, it could be reused and once it was in rotating [gravity] mode would need little fuel to maintain it.

OR, it is indeed just science ficton ??

This is totally feasible and probably on the cards for any lengthy space mission.

A rotating section of the spaceship could simulate gravity nicely maintaining healthy astronauts.

The movie 'mission to mars' did this well.

Rotation is the way to go. And probably the best way to do this is to have the space ship in two seperate sections and then have them tethered together and rotating. By adjusting the lenght of the tether between the halves, the speed of rotation can be controled and the amount of force adjusted.

2010 Space Odyssey had something like this to. 1 sec I will Google.

I couldn't really find what I was looking for. But yeah, be interesting to see what NASA comes up with to preserve bone mass for Mars astronauts.

If I remember talking about this at the Kellogg's Corn Flakes seminar I went to in 1962 (yes I'm old). The problem of gravity in or on-board a spaceship en route to say, Mars, for a long duration flight could be accomplished by rotation - as has been stated.

In fact I recall that if you rotate a space station (or similar) at one revolution per minute you get 1G ... that's gravity equal to what you have now.

It's enough to make you want to climb the walls!!

I wonder what the effects on the human body would be if they spun a spaceship so that it produced 2g's? If humans were going to visit a planet with stronger gravity they may have to do this one day.

Dave, If one rpm = 1G, it must occur at a specicific radius for given conditions. [please don't refer me to Newton or Hooke, I can't remember back to A level.] This would define the max' diameter of the crew compartment assuming they would only wish to move towards a lower 'G' factor, nearer to the central axis. If someone could do the Math I suspect the size isn't practical or NASA would have incorporated artificial gravity conditions into the Space Station.

[Astro Dave]

Hi Gyro,

Yes, thanks for addressing the 'math'. It was meant to be a generalisation.

As I said, it's just a memory from way back, something I was reading about at the time, and sure, it would depend on distances/diameters....

[Loxlee]

how would an onboard full body harness work out attached to the floor of the space craft with elastic straps pulling down on the shoulders and attached to wheels and railings for mobility ?

[q1111]

In this context, geoengineering means deliberately altering the atmosphere, land, or ocean to counter the effects of global warming.

fundamentally two ways to achieve gravity

constant acceleration (eg: 1g thrust) and

centrifugal force

LOL,,,, genius....
