NASA's 20-G Centrifuge Machine

Roland Piquepaille writes "Scientists from NASA and two U.S. universities are using a 20-G centrifuge machine that can simulate up to 20 times the terrestrial gravity to evaluate the effects of hypergravity on humans. This 58-foot diameter centrifuge has three cabins, one for humans -- limited to 12.5 G -- and two for objects and flying hardware. The goal of these experiments is to reduce the adverse effects that space travel can have on astronauts' physical heath. But by studying the health benefits of exercise on astronauts, the researchers also hope to help the rapidly growing senior population who, like astronauts, doesn't exercise much.

That thing spins fast!

Re:Effects of hypergravity?

[Clockwurk]

I think the pressures they are referring to would be experienced during launch, not during spaceflight.

It dosn't leave any bruises or marks either

John Paul Stapp [ejectionsite.com] disagrees (emphasis mine):

When the Sonic Wind had hit the water brake, it had produced 46.2 Gs of force. And for an astonishing 1.1 seconds, Stapp'd endured 25 Gs. It was the equivalent of a Mach 1.6 ejection at 40,000 feet, a jolt in excess of that experienced by a driver who crashes into a red brick wall at over 120 miles per hour. Only it had lasted perhaps nine times longer. And it had burst nearly every capillary in Stapp's eyeballs.

Why to you english-speaking people write Gitmo instead of Guantánamo?

That's what the Marines stationed there nicknamed it, long ago.
