Astronaut Scott Kelly on the devastating effects of a year in space.

….I can feel the tissue in my legs swelling. I shuffle my way to the bath room, moving my weight from one foot to the other with deliberate effort. Left. Right. Left. Right. I make it to the bathroom, flip on the light, and look down at my legs. They are swollen and alien stumps, not legs at all. “Oh shit,” I say. “Amiko, come look at this.” She kneels down and squeezes one ankle, and it squishes like a water balloon. She looks up at me with worried eyes. “I can’t even feel your ankle bones,” she says.

“My skin is burning, too,” I tell her. Amiko frantically examines me. I have a strange rash all over my back, the backs of my legs, the back of my head and neck – everywhere I was in contact with the bed.

Not read it yet, I save the weekend papers for a weekday at the pub, but I do really doctors were concerned with slowed heartbeats in space but that’s just what the heart does, when not battling gravity it puts in mininal effort. They have now adjusted the stats as to what a normal healthy heartbeat in space is.

Scott Kelly needs to HTFU.

I renew my request that someone conducts a space mission under reduced gravity (eg Mars gravity, using a tethered weight) to find the effects of that. We’ve got a timeline of five decades of information on the effects of zero gravity.

Would pressurizing the space station more reduce skin swelling?

Stronger modules needed?

It is pressurised. The swelling occurs when they return to Earth gravity.

That’s interesting.

I wonder if there is any other way to test that? It’s easy to study the effects of sustained increased gravity – just use a centrifuge – but much more difficult to study the effects of sustained reduced gravity.

Could do it on the moon.
Surely in the year 2017 it should be simple to establish a dwelling on the moon that could sustain people for long periods of time.
(We managed to get people there almost 50 years ago and now live in the future)

It could be done. Who pays?

China and India can duke it out.

I have now read that article, it’s pretty poor, doesn’t explain the illness nor the outcome.

The Moon – made in China, was on Kubrick’s Apollo set apparently…

It’s an extract from his book.

The symptoms described are mostly due to to a return to Earth gravity after an extended period of weightlessness.

But being such a realist he insisted on filming it on location.

Yeah I get that, but the article leaves it unresolved and unexplained.

I suppose we also have to wait for fashion to catch up, purple velour onesies with legs tucked inside boots is the go.

‘Cos, it’s just an extract from a book. Sounds like it would be a good read, put it on your list :)

Maybe they should study old people. Most of us feel like that in the morning.

They need better spacecraft

Rotating spacecraft to simulate gravity are needed and yes full atmospheric pressure and similar gas ratios are needed. If you arent close to 1g and 1 bar it will take a toll on your body.
