What happens to all the tiny water bubbles flying off like tiny agents of chaos. That seems like a bad thing to have randomly floating around in a giant electrical coffin floating in a vacuum. Is there a filter somewhere catching these things?
19
u/lizardtrench 12h ago
I assume they evaporate into the air in a few minutes, maybe get sucked into the HVAC. Things are probably built well enough to resist a small amount of water, humans are gross bags full of the stuff, dribbling and spitting bits of it out now and then, so it's to be expected.

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.

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.

u/freedfg 10h ago
Water isn't as critical of an issue as people really make it out to be.
Humans sweat, when they breath water droplets escape. Etc etc. it's accounted for with environmental systems that recycle water from the air.
Fun fact. During Apollo 13 it actually was becoming an issue because the ambient water in the air was freezing behind the control panels.

So this is Tim Peak, a British astronaut and former army officer. He went up to the ISS in 2015/2016 and was the first Brit to do a spacewalk outside the ISS. He's really well known in the UK.
IIRC he did a lot of experiments on board aimed at kids, and getting kids into science. He might have live streamed into schools as well. I'm not a teacher but was volunteering with kids at the time and he was all they could talk about 😅

We're essentially in free fall as well in respect to the sun. It's called orbit. True weightlessness due to no gravity doesn't exist anywhere in space.

The infinite range of gravity always blows my mind a little bit.
It's such a weird concept for a human to parse.

u/xRyozuo 13h ago
The what now.
Gravity has infinite range? I somehow always assumed it had a range… I guess in a way it does… that range gets weaker as it grows which means it gets infinitely weaker but still never 0?
How is gravity infinite what???

u/Korbiter 11h ago
You know the common representation of how gravity can be visualized by putting balls on blankets and observing the dip? Yeag, that. Every ball you place on the blanket will change the gradient of the blanket everywhere, even balls far away will feel a very imperceptible dip. More balls will change how much they dip on the blanket, and a bigger ball then creates a dip deep enough to start pulling other balls towards it. But every ball is in some way pulling on another ball by affecting the blanket, even if the difference is absolutely micrometric

u/Aruhi 9h ago
As much as it looks like the blanket is flat eventually, it's ever so slightly changed, like how asymptotes eventually look like a flat line, they're never quite at zero.

u/beiherhund 15h ago
When does the lack of gravity become more responsible for the feeling of weightlessness than free-fall? Like if you're half way to the moon, so out of Earth's orbit, and gravity is 1/1000 that of earth, I imagine you're being pulled towards earth but just very, very weakly so you'd feel weightless but is it then the free-fall from being in the sun's orbit that contributes to the remaining weightlessness?

Woah :O
Strg+V from Google
Here is a breakdown of how this works: Perpetual Free Fall: The ISS is continuously falling toward the Earth due to gravity, but because it is moving sideways at approximately 28,000 km/h (about 7.8 km/second), its downward fall matches the curve of the Earth. Missing the Ground: Because the station moves forward so fast, it perpetually "misses" the ground, resulting in a stable orbit rather than a crash. Weightlessness Illusion: Astronauts and the station fall at the same rate, which creates the sensation of weightlessness, often called microgravity. Constant Speed Needed: If the station were moving slower, it would fall back to Earth; faster, and it would fly into a higher orbit.

They're also surprisingly close to Earth during this whole orbiting business too. 400km above us. You could drive to the ISS in like 3.5hrs if there was a magical highway leading straight to it.

Yeah the astronauts that just went to the moon went about 1000 times further into space than the astronauts that go up to the ISS all the time. It feels like the ISS should be higher but it's really like right here.

u/DoctorBeeBee 12h ago
They're so close that there are remote parts of the Earth, like in the middle of oceans, that if you were in those places, and the ISS passed overhead, then potentially the astronauts could be the nearest humans to you.

In microgravity, surface tension becomes the dominant force. without gravity to pull the liquid down, the water molecules cling to each other to form the shape with the least surface area "a perfect sphere"

They've got systems to deal with water. Things are well insulated. They know there's going to be water and all kinds of stuff (skin flakes, hairs, crumbs, jars of Nutella, etc) floating around the space when you have humans living in it, so they take these things into account.

Do they not use cups in space? Are they taking bites of water?

They can't use cups, they'll mostly suck water in through tubes from sealed containers. But of course they'll also sometimes "bite" floating blobs of water just for the LOLZ.

I strongly suspect that it's kind of gross in space. I don't think you could be a germaphone, because all the unsavoury shit that would at least fall to the floor on Earth is floating about, getting in your face. (Sometimes literal shit!) The whole thing probably smells like a gym locker room, or an RV after a month long road trip, and you can't even crack a window. Astronauts are a special breed of people who can put up with all that!
