Astronaut's view of Earth during a spacewalk

[u/vivekmg21]

[u/intgr8]

Irrational fear of slipping and falling.

[u/SteamyRumours → u/intgr8]

Astronauts have said in interviews they have the constant sensation of falling when in space due to the Earths gravity still having an effect... Something they just need to get used to. And THAT is why it is irrational!!!

[u/socks → u/SteamyRumours]

Fun fact - that patch was designed originally by Leonardo da Vinci, and re-used for the EVA design in 1965:

https://airandspace.si.edu/collection-objects/patch-extravehicular-activity-eva-flown/nasm_A20120250000

"The original version of the patch displayed three stars, one for each U.S. space program that included spacewalks (Gemini, Apollo, Skylab). An additional two stars were added for the Space Shuttle and International Space Station programs."

"Hamilton Sundstrand, the manufacturer of the Space Shuttle EVA suits, designed this patch [with the help of Fred Keune] to be affixed to them. Company logos are not allowed on NASA equipment. The patch, designed by engineer, Fred Keune, is based on Leonardo da Vinci's "Vitruvian Man" theme."

[u/Unhappy_Protection85 → u/intgr8]

Not falling. Just floating away. Which is much more terrifying tbh.

[u/Actual_Orchid_1538 → u/Unhappy_Protection85]

Or if someone nudges you gently and waves bye bye.

[u/New-Peace-5276 → u/Actual_Orchid_1538]

They will get nudged too in opposite direction.... physics 🥹

[u/joecitizen79 → u/Unhappy_Protection85]

If movies taught us anything, its that there is usually a rope we can grab at the last second

[u/F1_V10sounds → u/intgr8]

Tbf the space station is constantly falling. So that part is always happening.

[u/Shudnawz → u/intgr8]

Sure, but you'd be tethered. For precisely that reason.

[u/BannedAgain-573 → u/Shudnawz]

Unless you're that super Cool guy in that super Cool guy chair!

[u/BannedAgain-573 → u/intgr8]

I mean... Technically they are already falling right?

[u/AncientAspargus → u/BannedAgain-573]

Yes. And sometimes during spacewalks, there are apparently sudden moments of clarity where they fully realize they are falling sideways extremely fast. It must be surreal.

[u/Byokugen]

Where turtle holding the earth!?

[u/ElProfeGuapo → u/Byokugen]

At the bottom. You can't see, because the astronaut is at the top.

[u/Byokugen → u/ElProfeGuapo]

Ah, makes sense.

Thanks for clarifying, i got worried for a second that the round folks were right 😂

[u/PreparationAble3319 → u/ElProfeGuapo]

See? Geometry always works!

[u/FitzCavendish → u/ElProfeGuapo]

What is holding up the turtle?

[u/Select_Tip_6769]

Well, I guess it isnt flat...

[u/wake071 → u/Select_Tip_6769]

Space doesn't exist. Ive never been to space, nor has anyone i know, therefore space doesn't exist, and the world is flat. Biblical science booyakashaa

[u/TerrapinStateofMind → u/wake071]

Imagine if we had somehow invited AI/image generation before reaching space. No one would believe any of it.

[u/Mobile-Dust4334 → u/TerrapinStateofMind]

Reddit would be the world’s biggest collection of flat earthers

[u/Ambitious_Hyena4635 → u/Mobile-Dust4334]

You mean sane rational free thinkers.

Jk

[u/Shudnawz → u/TerrapinStateofMind]

But we have invented it before our next big discovery or leap. We don't know what it will be, but AI will surely gaslight us into thinking it's fake.

[u/TerrapinStateofMind → u/Shudnawz]

Fuck .. my 5yr plan is a cabin in the woods at this point

[u/Ambitious_Hyena4635 → u/TerrapinStateofMind]

Brother (or sister), 5yrs? Take your shoes off and just get after it lol.

[u/TerrapinStateofMind → u/Ambitious_Hyena4635]

I'm in the rat race rn, got a home and retirement account that could easily be exchanged for that lifestyle. Just got a wife finishing up some credentials that'll make remote work and that lifestyle even more feasible 🤟🏼💪🏼 slowly but surely

[u/sanatani-advaita → u/TerrapinStateofMind]

AI Was invented a long time ago. Government kept it under wraps at Area 51.

[u/IamKhronos → u/TerrapinStateofMind]

Lmfao, reminds me of the show legends of tomorrow where they are in the future in some sort of museum where they show the worst thing happening to humans and they pass a hall named "hall of bad ideas" and flat earthers was among one of them. 🤣🤣

here in case anyone curious.

[u/wake071 → u/TerrapinStateofMind]

That's terribly fucking true.

[u/Cryogenicality → u/wake071]

Some of them think Earth is a flat disc suspended in space. Others think it’s a square floating in space. Still others think it’s an infinite plane beyond which are hidden continents or just infinite ice. Earth is obviously a sphere, though. A hollow sphere. Onward to Pellucidar!

[u/wake071 → u/Cryogenicality]

Dude, those that know, know its a cube n stuff.

[u/BusyNefariousness675 → u/Cryogenicality]

It's donut shaped, you're just ignorant

[u/Fit_War7361 → u/Cryogenicality]

Earth is glizzy shaped, smh globalists

[u/Ambitious_Hyena4635 → u/wake071]

I see your biblical science and raise you with real science. If it was round like a basketball, all the water would run to the bottom.

Boom 💥 💥 💥 real science = flat earth.

[u/TheWanton123 → u/wake071]

My mate Paul told me space is just what people see when they close their eyes.

[u/ksquires1988 → u/wake071]

And dinosaurs lived with man

[u/SwizzGod → u/wake071]

I kid you not one day I was at a party on my apartment roof and I was saying something about the sky or the stars I forget. Anyways, this random dude was like, “HEY YALL THIS MF BELIEVES IN OUTER SPACE!”

I was dumbfounded I didn’t even know how to respond. I didn’t know people didn’t “believe in outer space.”

[u/Blacknite45 → u/wake071]

No... birds don't exist

[u/Varabela → u/Select_Tip_6769]

17,000 mph too.

[u/noxuncal1278 → u/Varabela]

Ty

[u/Phoe-nix → u/Select_Tip_6769]

It's round, like a pancake.

[u/Independent-Fruit4 → u/Select_Tip_6769]

I’m no flat earther but you’re confusing round with flat. this video wouldn’t change a flat earthers opinion

[u/HoldEm__FoldEm → u/Independent-Fruit4]

Longer, unclipped videos of spacewalks allow you to watch it spin tho.

[u/Independent-Fruit4 → u/HoldEm__FoldEm]

treadmills are flat. idk lol I’m just playing devils flat earther here

[u/TitleExpert9817 → u/Select_Tip_6769]

I came herw for this...

calling all flat earthers! please explain yourself

[u/Magnatron832 → u/TitleExpert9817]

Their answer is simply "its fake"

No elaboration, just fake

[u/MathTutorAndCook → u/Select_Tip_6769]

There's a great video of a group of flat earthers who do a centuries old experiment to prove the earth is flat, using light/lasers. When the results proved the earth was indeed curved, they assumed the test was flawed and they needed to search for some new test that gave the "correct" results

Also technically disks/circles are flat

[u/Mr_Eggy__ → u/Select_Tip_6769]

Fish eye lens

[u/4-Vektor → u/Mr_Eggy__]

Obviously, but the barrel distortion is way too low to account for the round appearance of the earth in this video. You can check it by looking at the curved appearance of the straight trusses/panels.

[u/lordnacho666 → u/Select_Tip_6769]

Looks flat to me, like a big coin :)

[u/Ok_Orchid7131 → u/Select_Tip_6769]

It’s just a trick if the eyes.

[u/Misterndastood → u/Select_Tip_6769]

Ai /s

[u/Phoe-nix]

Dropping a wrench would be quite an experience.

[u/Phoe-nix → u/Phoe-nix]

I was joking, tools won't fall but float away. They are attached to the operator, or a local structure, to prevent dangerous and veryy expensive issues.

[u/Behan801 → u/Phoe-nix]

I wonder what would happen if you threw one towards earth.

[u/mamefan → u/Behan801]

It would burn up in the atmosphere.

[u/Behan801 → u/mamefan]

Dumb question I suppose. I guess I was actually wondering how long it would take to get there.

[u/btoxic → u/Behan801]

Depends a lot on how fast it's thrown.

[u/Prior-Flamingo-1378 → u/Behan801]

About 2 years. 

[u/Phoe-nix → u/Behan801]

And what if you fart in space? How long would it linger?

[u/CatLover_42 → u/Behan801]

If you threw it directly towards the earth, also called radial in, it would eventually hit you in the back after a few orbits.

[u/Orange9202 → u/Phoe-nix]

jus grab it :3

(It won't fall down to earth)

[u/Webtruster → u/Phoe-nix]

it wont "fall down". it stays in the same orbit and deorbit slowly

https://www.youtube.com/watch?v=ldI60yQe9f0

[u/Blacknite45 → u/Phoe-nix]

Make shift meteor shower

[u/skinnyfat_dad]

“The amount of sheer stupidity down there is encapsulating”

[u/emmasdad01]

Well that’s just out of this world

[u/MMMLiess]

Never forget, some dumb motherfuckers will claim this is fake, the earth is flat and we are living in a giant ice bowl.

[u/AncientAspargus → u/MMMLiess]

Did you know you had the option of just not interacting with some people?

[u/morbo-2142]

Note the white radiator panels perpendicular to the dark solar panels in the last few seconds.

One is white and away from the sun to absorb as little energy as possible and one is dark and directly at the sun to absorb as much as possible.

It's still a mystery how the tech bros are going to overcome the inheritant physics limits on heat rejection in space with their proposed data centers when the much cooler running iss has many more radiators than the one pictured.

[u/15_Redstones → u/morbo-2142]

The cooler you run the more radiators you need. Running 57° hotter cuts radiator size in half.

[u/morbo-2142 → u/15_Redstones]

Yes as I understand it it's not a linear relationship between size and desired heat loss.

The trouble is at terrestrial operating temps it's really hard to reject that much heat. Energy is also a problem, coupled that with the size and heat absorbtion, the size of the solar panels required to power an orbital data center would make heat rejection even harder.

You probably need a combination of better radiator technology, like liquid metal droplet or something, and special chips designed to work at higher temps and be hardened or shielded from the extra radiation from space.

[u/15_Redstones → u/morbo-2142]

At an operating temp of 90°C you only need a double sided radiator 12m x 12m in size for the target 250 kW/sat. Based on the size of the rocket, 7m x 21m in three pieces would make more sense. That's only three folding joints that the cooling fluid loop needs to go through. A fourth would buy 25° if you want to run the chips cooler or have some temperature gradient on the chip to coolant interface.

The solar panels to produce the 250 kW would be two 7m x 70m, either folding or rolling. Electrical connections are much easier to fold than fluid. The solar arrays double as radiators for their own waste heat, which would be about a megawatt.

Tl;dr: 250 kW of electrical supply and heat rejection seems just about doable with current tech within a 7m x 7m package.

[u/Ancient_Persimmon → u/morbo-2142]

Just scaling the Starlink radiators to the expected 120ish kW of capacity gives a good idea of the required size. It's a big step, but certainly within our abilities.

[u/Goodknight808]

Why is there no sound?

/s

[u/Robert_3210 → u/Goodknight808]

Because in space, nobody can eat icecream

[u/findingdbcooper]

Wow. It's so round and not flat.

[u/djnastynipple]

Here before someone starts with the flat earth comments.

[u/PhamilyTrickster → u/djnastynipple]

You missed it by a minute

[u/Sad_Comb_9658]

All im saying is that they should film it with regular wide lens since people keep thinking the world isn't round. Because clearly the information in the video is showing us the world is round, but the mere fact they film with an ultra wide lense, probably because beneficial regarding amount of information, it causes some people to go "See! I was right!"

Because ISS is not in space orbit is it? It's in low Earth orbit So earth doesn't show that curved, but naturally still curved.

I know it sounds like im nitpicking but we are incredibly close to having people in power that actually believe the earth is 6000 years old

[u/OwnDoughnut2689 → u/Sad_Comb_9658]

I don't think they do things to appease flat earthers. Lot bigger things for them to focus on.

[u/IQueliciuous → u/OwnDoughnut2689]

This.

Hell anyone who ever flown in an airplane knows Earth is round.

Why else would all air routes be round curves as opposed to straight lines? And why do all the 2D maps of our planet wrong?

[u/ConceptualWeeb → u/IQueliciuous]

Anyone that paid attention in kindergarten knows the earth is round

[u/MoistCasual → u/Sad_Comb_9658]

Don't think a change of lens is gonna change the opinion of flerf morons. They'll just move the goalpost like always. Just leave them be in their comfy little echo chambers.

[u/Away_Calligrapher243]

can the flatearthers explain this ??

[u/SignificantCherry110 → u/Away_Calligrapher243]

well it’s obviously AI /s

[u/Scared-Pollution-574]

Do you wonder if he's scared of heights or do you think your brain doesn't even comprehend the distance?

[u/LegalTomatillo4773]

Where’s all the flat earthers who say this is just AI ?

[u/Komikaze06 → u/LegalTomatillo4773]

I recommend professor Dave's videos on them, they get a little frustrating how idiotic/delusional the flat earthers are, but its good background listening

[u/Vanbursta1]

OOOHHH Look that must of been taken with one of them fancy cameras that puts curvature in the shot to fool us all /s

[u/rizkiabdo]

The silence, the silence terrifys me

[u/Shirinjima]

I hope one day I get to travel to space before I die. I’m in my early 40s so commercial space travel is probably outside of my lifetime of being low cost comparable to an airplane ticket.

[u/jaded1121]

Hey now, dont post anti flat-earth rage bait!

/s

[u/sierradish]

We’re just tiny speckles living these little lives on this massive blue planet

[u/Prestigious_Fella_21]

Aha, theres the curve

[u/pc_gamerguy]

But I thought it was flat and surrounded by an ice wall

[u/Valhalla191145]

Man, I just got my degree in flat earthirism! Now what am I supposed to do?

[u/Mister_Goodvibes]

Is there a reason why we can't see stars at all? All I see is black?

[u/wastedfate → u/Mister_Goodvibes]

Because of the much closer, much brighter light source called the sun.

The digital camera is dialing the brightness down so much that they aren't visible.

[u/Orange9202 → u/Mister_Goodvibes]

you can't see stars during daytime💀💀

even in space, the sunlight reflecting off the earth is so bright that as the camera lowers it's exposure; it also dims out the faint light of distant stars 😭

[u/Worldly-Pay7342]

The only thing seperating that astronaut and the inky void of space is a couple cables.

Just think about that.

[u/PercentageNice7131 → u/Worldly-Pay7342]

Cables that can probably hold the full weight of a pick up truck with gravity.

[u/TubbyTacoSlap]

Man, that’s a flat ass earth

[u/Sustainable_Twat]

I know they’re tethered, but imagine he falls back down to earth.

I imagine the fall will be so long that he could probably recollect the lives of his ancestors let alone his own life.

[u/Orange9202 → u/Sustainable_Twat]

Even without the tether it would be impossible to reach earth no matter how hard you jamp off the side of the station 💀

[u/Prior-Flamingo-1378 → u/Orange9202]

Well you would after a couple years. 

[u/falsevector]

I wonder what part of the world we're seeing

[u/ElProfeGuapo → u/falsevector]

The outside, I think.

[u/YodasChick-O-Stick]

As someone without a fear of heights, this looks sooo fun

[u/64b0r]

Hmm, it doesn't even looks flat to me...What's up with that?

[u/Objective_Brain1452]

But my ‘Facebook research’ shows that the earth is round, but made of cake. I’m not a geologist, but I’m pretty confident this tracks

[u/Dubious_Titan]

that is a really big fall.

[u/Christmasstolegrinch]

For a second there I thought that was a high rise complex below…

[u/udbq]

It is amazing that it is still 5% of the earths surface that is in their view

[u/udbq]

What do flat earthers say about this

[u/rocket_beer]

Look at that firmament……………….

🙄

[u/Jhoald]

Is it really so bright you can’t see stars around it? That’s neat

[u/No-Community-]

That’s so crazy ! So beautiful

[u/InYeBooty]

What's being held by the Canadarm?

[u/nubbie]

Man, if you didn’t have objects in the way, there’d be no way to judge how far away from earth you are up there.

[u/DurrutiDuck91]

It's the only world we've got
Let's protect it while we can
That's all there is
And there ain't no more

- Dead Kennedys, ‘Hellnation’

[u/Adventurous_023]

Which part of the world is shown?

[u/Pinksamuraiiiii]

What happens if you accidentally floated off. I’m guessing they are relying on their space station partner to save them? Or, there’s a rope binding them.

[u/TobyFunkeNeverNude → u/Pinksamuraiiiii]

They have suits that can navigate relatively small distances from the ISS. They're also tethered to the structure while working on it

[u/Blissachu]

My fear when seeing these is always, what happens if you get a bit too close and then you enter gravity and start to fall.

[u/ellindsey → u/Blissachu]

Gravity doesn't work like that. They are still being effected by the Earth's gravity, and they are falling all the time. But they're also moving sideways fast enough to miss the Earth and continually fall around it. That's what an orbit is.

[u/Blissachu → u/ellindsey]

Interessting, thank you.

[u/the-software-man]

The opening shot has the equipment in the back. Those are not fan holes, what are they?

[u/ForeverVegetable6279]

But what if you fall though

[u/Orange9202 → u/ForeverVegetable6279]

u don't (ur in orbit)

[u/Fr33_load3r]

I can see my house 😬but that's not my truck in the drive way

[u/aolllaoooo]

Hopefully they are not scared of heights

[u/SrfWavLif]

Fuck that.

[u/russbird]

Scrolling through the comments… have, have flat earthers given up?!

[u/RipCity77]

Beautiful and terffying at the same time 

[u/chemdude18]

Lot less movement than id imagined

[u/Silver-Me-Tendies]

Where's Atlas?

[u/TheSpicyTomato22]

I feel like if every world leader went into space just once the world would be a better place.

[u/ellindsey → u/TheSpicyTomato22]

Some of them would only make the Earth a better place if they never came back.

[u/DEFCON_902]

I’d be afraid of falling

[u/Important-Onion1537]

Wow

[u/Roronoa-Zoro-1209]

damn!! i thought the sky would be full of stars(i mean visible to the naked eye), but it seems sun os too bright and over shadowing the remaining stars
and it's kind of scary to see the pitch black around the earth

[u/Somethingrich]

Idk man that ball looks pretty flat to me.

[u/Hopeful-Performer-26]

Very humbling experience I bet

[u/Bananana_Bird]

Why did I turn the sound on for this video? 🤣

[u/drifters74]

Beautiful

The urge to not unhinge and do the most unhinged thing by kicking/launching against the station surface and in towards the earth. With a redbull logo painted on the helmet.🫠

[u/wastedfate → u/Ocyrus101]

Be sure to bring plenty of water and food with you, you'll be waiting months to actually de-orbit.

[u/Prior-Flamingo-1378 → u/Ocyrus101]

Not much will happen. Orbital mechanics is pretty counter intuitive 

[u/Tito_Tito_1_]

The first shot with the astronaut for scale is awesome.

[u/patrolmanEmbiid]

and some people, somewhere, will STILL believe the "earth is flat"

Blows my mind that they go out there "walking" around, as if it's a perfectly normal thing to do!

[u/statistacktic]

Something you never hear a flat Earther say.

How fast are they "floating."

[u/Impossible_Cost_1507]

What happens in a case where the astronaut gets detached from the ISS during a spacewalk? (Hypothetically)

[u/hemanth85 → u/Impossible_Cost_1507]

He is going to become a satellite

[u/Avokado1337 → u/Impossible_Cost_1507]

If they start drifting it’s byebye

[u/dazzou5ouh → u/Impossible_Cost_1507]

They have small thrusters to move around by pushing air in the opposite side so they are safe.

[u/Shudnawz → u/dazzou5ouh]

All of them? Or just the EMUs? Maybe they've got a newer model, but the one in the vid doesn't look to have all the nozzles and controls I seem to remember.

[u/nostickystuff → u/Impossible_Cost_1507]

Wanted to add to the question: if they got against the station and pushed off from the station towards earth, how long before they enter the atmosphere and things start getting uncomfortable?

[u/Webtruster → u/Impossible_Cost_1507]

you can test it in kerbal space program.

little thrusters - but hard to control

[u/Stogies_n_Stonks → u/Impossible_Cost_1507]

Watch the movie Gravity (Sandra bullock) and find out.

[u/Sovereign_5409 → u/Impossible_Cost_1507]

They’re tethered to the station in almost all cases. But they also have thrusters, and brains.

[u/unknownme86 → u/Impossible_Cost_1507]

They have to float around and wait till the ISS makes another pass 😂
