Magnetic fields?

Is it a good idea to subject the astronauts to magnetic fields strong enough to produce an attraction of 0.5 g? That's a lot of magnetism. --The Killer Rabbit aka Nevin 13:42, 16 April 2006 (EDT)

I couldn't think of a way to increase the gravity beyond 0.1 g. A 22 meter object rotating at 2 RPM generates about 0.1 g. You'd need a 400 meter object rotating at 2 RPM to generate a field of 1 g. Since the habitat, when rotating, has a radius of about 22 meters, and 2 RPM is the most rapid rotation possible without inducing nausea and sickness, we're stuck at 0.1 g. (All the facts are on wiki/artificial gravity) --Foo1 17:55, 16 April 2006 (EDT)

Skylab used a system where the astros' boots slotted into grids on the floor. --The Killer Rabbit aka Nevin 18:44, 16 April 2006 (EDT)

But we need real gravity or else our bones would melt. The problem is not staying on the floor; but making sure that your bones don't liquefy.--Foo1 22:18, 16 April 2006 (EDT)

Gravity Simulation

Alright, this one has to be good. How do you plan to simulate .2g? There are some places where pseudoscience were always required because we simply can't simulate it. Low gravity is one of them. The astronauts won't feel low gravity, so yo simply can't pretend it exists. During in-flight EVA's, the astros walk on the surface of the AYSE drive to do repairs. When on planets, they walk on the planet surface. Why do the planets feel like earth gravity? Because that Habitat creates a very limited field in the surrounding area to make it so. This is for health reasons, so the astronauts don't lose any bone mass, etc. (or whatever other reason you feel like making up). You can use a different explanation if you want, but I'd really avoid trying to say you have low gravity when it is impossible to simulate. - Avacar 08:36, 17 April 2006 (EDT)

I am positivly stumped...though I beg people not to replace my article with some random graviton-crazy physics proposal. --Foo1 12:09, 17 April 2006 (EDT)

Interesting attempt to explain it away. As an alumnus, I must leave it up to all of you together to decide whether that's plausible enough. At least it does remove the need for some strange pseudoscience explanation (which is good), but you're once again telling the astronauts what they feel, which is dangerous. In general, I try not to put the astronauts in a situation where they can directly argue with observed/recorded info, as this can lead to conflicts. Will the astros experience 1g (because of their mental state) but the instruments record .2g (or whatever)?- Avacar 14:47, 17 April 2006 (EDT)

The current model of the power grid software includes a switch for artificial gravity. Does this indicate that there is some form of artificial gravity being simulated, or is this just the centrifugal force bit? --The Killer Rabbit aka Nevin 15:20, 29 April 2007 (EDT)

Too many methods

So far, this article says we have four different ways of generating gravity:

• The Habitat rotates, producing centrifugal force
  • Issue: The engines are beneath us. To produce a downward force, the Hab has to flip end-over-end, which makes controlled acceleration really hard.
• Astros have magnets in their shoes
  • Issue: This doesn't stop our stuff from flying around
  • Issue: These would have to be really strong magnets.
• The Habitat/AYSE Drive's acceleration presses us to the floor
  • I like this idea, but it doesn't help us if the engine is turned off/conks out
• The Graviton Projecting Devices send some gravitons behind the Habitat, which attract the Astronauts
  • Problem is that the net force from gravitons will still be forward; since the singularity attracts the astros with the same acceleration as the AYSE Drive itself, the astronauts do not accelerate relative to the AYSE Drive, so no gravity is simulated

I think that the acceleration-due-to-engines effect is the best one to go for; too bad it only works for the Hab's propulsion method (which doesn't propel the astronauts directly). --The Killer Rabbit aka Nevin 14:34, 6 May 2007 (EDT)

Gravity Onboard the Hab

Gotta write that down.. "Generated between two grav-charged plates", and using the gravitrons produced to create gravity onboard the Hab.. How's that sound? Centrifugal force.. sounds awkward. Plus 0.2g is pretty far from what you'd feel during the mission. :P ---Wernstrum, Stargakat, Jonas 01:10, 17 April 2010 (EDT)
