Sleeping in Space /Zero G

[ottarrus]

RCAF Colonel Chris Hadfield is a Canadian Astronaut with three missions under his belt.
11 years ago, he did a video on what it's like to sleep aboard the International Space Station. I thought this might be of interest to those into 2300AD or middle-tech Traveller.
Enjoy.

"Gunny, Is this a cupboard?"

"No sir, that's your stateroom. You'll be sharing it with the Ecks Oh."

Hot bunking too. DO enjoy your stay, sir....

 

[Condottiere]

Hot bunking?

Ride sharing.

I wonder what the internal temperature of the ISS is?

On-Orbit ISS ECLS Hardware Distribution as of February 2010 (Source: NASA/ISEC)
And the document quotes these values:

• Cabin pressure nominal range: T = 14.2 to 14.9 psi
• Oxygen and nitrogen distribution: P = 93 - 120 psia, T = 60 - 113°F from Node 1
• Oxygen Recharge: P = < 1050 psia (max 16 lb/h), T = 25 - 113 °F from PMA3
• Nitrogen recharge: P = < 3400 psia (max 3 lb/h), T = 25 - 113 °F from PMA3
• Cabin Temperature nominal range: T = 65 to 80˚F (18.3 to 26.7°C)
• Cabin air velocity: 10 to 40 feet per minute

What is this psi nonsense you speak of? Talk in pascals like a civilised sophont!

Thanks, I was partly wondering because his space-jarmies seemed very warm. Add a sleeping bag and being in that small space and it seems like it would be too warm to sleep comfortably

I admit, I liked the space PJs.

The sleeping bag is so that nothing wanders around.

What I haven't seen anyone mention and I know it was not considered when someone came up with the idea for "grav beds", when astronauts go into space to live for prolonged periods of time, they spend the first 2 weeks or so with vomiting and diarrhea due to the lack of gravity while their bodies adjust. How does Traveller handle this and why would anyone want to sleep in a bed that makes them explode out of both ends?

 

[Arkathan]

The great thing about a grav bed on a ship with artificial gravity, is that if you start feeling nauseas you just get out of bed, or turn up the grav.
You only have to use it while it is fun.
You aren't stuck in zero G. Unless you are on one of THOSE ships...

True, most of this is fixed with artificial gravity and such. The grav bed still confuses Me though. That is sleeping in zero-g. Better to sleep in a sensory deprivation tank. At least that won't make your body react like a perverse fountain. lol

I think its a trope from Niven and Heinlein (maybe not the latter) as an experience for two (or if Heinlein's involved, three).

 

[Condottiere]

There are a number of considerations.

Medically, default, you want to maintain that Terran norm gravity.

You have some leeway, without it having an effect, usually badly, between seventy to one hundred forty percent.

If I was doing a workout, I might increase it to one hundred forty, while if I wanted to relax, I could lower it to seventy, percent.

If I wanted to try the Kama Sutra, I could temporarily lower it further, without losing control.
