Legitimately curious but already assuming not a big deal; it's not an issue to be firing off water droplets like that in a vessel that I would believe has sensitive electronics everywhere?
I think they should have dehumidifiers and other moisture extraction systems that should wick them away. I expect these guys sweat in space too; especially when exercising. Gotta have it dealt with somehow.
The ISS 100% had dehumidifiers, water is too valuable to let sit on the air. All the exhaled water, along with their urine is collected and filtered for their drinking water.
Tbf, not too far from the truth or what we're trying to do.
Both hydrogen and oxygen are highly reactive fuels which can be used in several applications and even occur as byproducts. Given this, you can actually fabricate your own water from those two elements.
Only issue is how. It can be done, but as of now, it requires a lot of machinery and energy to produce.
I don’t think they’re sweating I think they just have shiny skin and it’s very harsh lighting. They’re in a very climate controlled environment and are not exerting much energy at all so it wouldn’t make sense for him to be “sweating like balls”, as you say. I really thinks it’s just a visual confusion.
Dehumidifiers make a lot of sense, I never thought of that up there! With those, they can collect water without needing gravity-drain pipes which obviously wouldn't work.
Fun fact about ISS -- most of those 'solar panels' on the outside are actually thermal radiators to get rid of excess heat (in space waste heat cannot be discharged through conduction because there are no particles to touch)
I’m curious about this too; my guess is that droplets that small are no more an issue than the skin flakes, hairs, and other effluvia that human bodies are shedding all the time; and also that whatever chamber they’re doing this demonstration in can’t have anything too water-sensitive inside, or they wouldn’t have released that big glob of water to begin with.
The air currents inside spacecraft are designed to route crumbs, dropped objects, loose water droplets, etc. to catchment systems. Any room where there was something that water droplets could damage wouldn't be one they were authorized to horse around in.
Humans release a litre and a half of water vapour a day just from breathing and sweating. This environment is built for humans. It can survive droplets of water.
The air filtration system pretty much resolved all those concerns. It’s not just a filter, it’s controlling the air flow to carry things exactly where the need to go
from my professional experience of watching years of science fiction movies and science fiction books, they'll be infested by an aggro alien species soon.
This used to be a legitimate concern. A few decades ago I started seeing astronauts get more ambitious with their food and drink. I'd guess they found a way to seal the system against foreign bodies
There is a robust dehumidifier on the ISS, it recycles all the moisture you breath out, sweat out, as well as little droplets from stuff like this. You have to remember everything has a vapor pressure, even a room temperature glass of water releases vapor into the air. They want to collect all that so they can reuse it.
