A couple days back, spacers got promised a new sleeping bag. This resolves a problem for airbreathers in microgravity for extended periods: fluid builds up in the skull to such an extent that it deforms the eyeball. Yeowch!
I wonder if this contributes to the brain damage as well, although - it seems - the eyes go first. UPDATE 5/17/22: Besides Russian-approved exercise... and their space-pants.
As a rule I don't want people in microgravity for extended periods. If we're going anywhere past the Moon, or even if we're hanging out in TLL1 or Gateway or wherever before even landing on the moon, we should be Spinning The Drum. But.
Say we have a shuttle that goes a little astray and runs out of sufficient propellant to return. Or, say we have an asteroid mining ship that needs to chase after a phat nugget of platinum. Might be a week to catch up to that, on a shoestring vessel without spin. And we'll be hibernating. Here, I can see this bag of use.
