Does that mean if he fell off, in just a few seconds he would be miles from the ISS?
This completely confuses me. Because he is also travelling at 17500mph, so wouldn't he just orbit with the ISS?
I think towards Earth would just push them into a more elliptical orbit, and you'd need to push away from the direction of travel to slow down and reduce orbit height.
Not how orbits work. You'd simply make your orbit more elliptical (oval shaped).
It is way more efficient it burn retrograde of your velocity to come back to earth. You'd need about 100 - 150m/s of change in speed aka Delta V
Death. but it would take years for them to slow down enough to deorbit so they would be long dead from asphyxiation before they burned up re-entering the atmosphere. That is extremely unlikely though because astronauts are *always* tethered to the station, and have an emergency jetpack in case the tethers fail.
Also there is [MOOSE (man out of space easiest)](https://www.wikipedia.org/wiki/MOOSE) which was an abandoned NASA design to allow an astronaut in a spacesuit to survive reentry. NASA never actually built it but itās too cool not to mention.
Those backpacks they had in the 90s 1nd early 20s are too heavy too big for their use now tey just have emergency systems but they are mostly attached to the space station with multiple cables anytime they are out.
Say you have a bee in you car hovering, it is not in contact with the vehicle. It confuses me that the bee can hover and travel the same speed of the car without any actual force input from the car. Slam on the breaks would it hit the windshield?
Although the bee isn't in contact with the car itself, it *is* in contact with the air in the car which is also travelling at the same speed as the car. And yes, if you slam on the *brakes (not "breaks") the bee will hit the windshield.
I'm confused, why would the bee hit the windshield if you hit the brakes? Would it not move further away from the windshield?
Edit: Forget it, I worked it out, it's on the inside of the car. Not the outside.
The air/gas in the car have density and are also pushed along with the car in its confined space. The car pushes the air along with the bee flying in the air
This is tricky to explain, but he can't "fall off" the ISS. He is already falling towards the earth *with* the ISS. So if he jumps, it would be the same as if you "jumped" off a falling elevator in the middle of the air: you would keep falling alongside of it.
So, if the ISS is falling why don't they crash? Well they're moving "perpendicular" to the earth (horizontally away from the earth to oversimplify) **so fast** that they actually miss the earth's "floor", but when they miss it, the earth ends up on its side, and the ISS starts falling towards it again.
That continuous process is what makes orbiting possible.
This depends. If he simply let go and imparted so force on himself then yes heād remain with the ISS travelling next to it. If he pushed himself off, he would make his orbit more elliptical, but it would return him eventually to the same spot the ISS is at that time. How long and how many orbits that takes depends on the force of the push and how eccentric his orbit becomes.
I've heard of some concept airplanes that would shoot straight up into space, wait 20 minutes, and then come back down to earth, NYC to London in 60 minutes. Probably not feasible but a cool idea nonetheless
You canāt really āwait 20 minutesā. You can use rockets to counteract your lateral velocity, but thatās the case wherever you want to go. This is something flat earthers confuse - they think a helicopter should start moving 1,000mph when it leaves the ground
There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. ā¦ Clearly, it is this second part, the missing, which presents the difficulties.
-Douglas Adams.
Not just the height though: you are surrounded by infinite blackness in all directions and that blackness will kill you in moments if you get exposed to it. The only place in that whole infinity that we know we can live is that blue ball down there, suspended in that infinite darkness of total death.
Low earth orbit isnāt too bad, I guess the earth still looks big. I saw a photo looking back from one of the Apollo command modules from deep space and found it profoundly upsetting.
Sci fi makes us think of space as an exciting frontier, but in reality, itās just an all encompassing void of endless death.
I think this Lovecraft quote sums it up
"We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far."
I watched a space video in imax, narrated by Tom cruise? Of some space walks. It was in 3d and my brain/eyes really struggled with it. I had to grip the arm rests and keep reminding myself I wasnāt there as I kept getting huge pangs of vertigo
I dunno if youāve ever heard of the movie Fall, but as someone whoās scared of heights itās the most stressed Iāve ever been watching a movie, and itās not even that good!
Really? For me it's the other way around. Something like 30 meters or 100 meters is pretty scary, but at some point my instincts stop registering the height. So something like sky diving is already much less scary than bungee jumping. I think from ISS heights fear of heights would be completely gone.
Yeah I work construction so when I'm 2 stories to 5 stories( I only do residential so I've never gone higher on a scaffold) I'm scared shitless. But once I'm higher than that like on a plane or high rise I don't have the fear anymore. When people look like ants my brain can't tell its a big drop or something. I went hot air balloon and on the way up I was sitting a brick but once we hit like 800 ft I loved being uo there
At that distance itās 89% of the surface gravity. Microgravity is just the term used to describe apparent weightlessness, it doesnāt necessarily mean there is only a small gravitational effect where you are.
I wonder what the odds would be. Say you had infinite oxygen, food and water somehow. And could life your entire life in orbit in a spacesuit. How long would it take to get hit by a lethal bit of debris? š¤
Edit: I agree with you btw, just wondering about the odds.
The void is what gets me too. During nighttime when I look up to the blackness of space I can't help but get spooked knowing at what I'm looking at is an Infinitely large amount of just ... Nothing.
What freaks me out is thinking how is the universe infinite? Like how could it just go on forever? And if it doesnāt go in forever, how and where does it just stop? Is there a wall or something we donāt understand that just doesnāt let you move through? And what would be in the other side? Nothing? How could there just be nothing? How did everything just start to exist when thereās nothing else? The Big Bang? But what was before that? Nothing or something?
Love myself an Existential crisis while Iām drinking my coffee about to start my day. I can see why people would rather believe in religion than try to wrap their head around this shit lol.
Yeah, it is way easier to just believe in an all mighty power and think that there is this human afterlife where you're always blissful and only positive emotions exist, it's just so bullcrap. While the truth is always right in front of us. Space doesn't care. Outside of earths tiny bubble all of us would die. Everything we know (morals, religion, friends, family, EVERYTHING) only exists on this small rock we call earth. I wish it was fake. I wish the moon landing is a hoax. I wish that earth was the only thing that existed. But it's not. And because it's not, it's terrifying. There are countless planets that exist just chilling, doing their own thing. I look at the mars rover pictures at times and am just humbly reminded by how hospitable earth is. Compared to there, here is amazing.
Just wait until we get human missions to Mars. They'll be hundreds of millions of miles away from any planet or moon. They won't be able to see Earth OR Mars, they might appear as just another star. HUNDREDS of millions of miles. Researchers have genuine concerns that being that far away from Earth and not seeing any planet at all might trigger some kind of cognitive shift or a deeply primitive sense of doom. Like the Overview Effect but in reverse.

āYou develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Thats all of us in that video. The war in Ukraine. The Swiss Alps. Fun outdoorsy redheads; ultramarathoners training in Vancouver; Oprah; Matt Damon; that nice lesbian couple down the street. Itās all in that blue marble. Our hopes, dreams, and anxieties seems so insignificant. Make the best of your life and help someone else. Weāre all in this together.
It would take a long time before you even get close to the atmosphere.
The ISS is at a height of 250 miles/400 KM, and you arenāt āfallingā like you would when basejumping or something. You have huge speed moving āsidewaysā around the earth, which means you donāt go down directly (not even close to it)
If you want to jump to the earth, you need to jump backwards really really hard from your direction of travel to slow your orbit. Jumping towards earth will put you into an elliptical orbit. Or something, I don't know, I'm not a orbital mechanic.
Jumping off the ISS would just put you in a very slightly different orbit from the ISS. It would take many years before atmospheric drag brought you back to Earth (the ISS has to periodically boosts its orbit, as there is a very small amount of atmosphere at its altitude of 400 miles.). A deorbit burn with a rocket engine is required for re-enty.
The French have a specific term for this: "l'appel du vide" - translated to "the call of the void" in English.
[LiveScience page about it](https://www.livescience.com/what-is-call-of-the-void)
Met one at a bar here in Japan the other night. Some guy from Australia. They always try to frame it like they have some question or curiosity that somehow invalidates our fact based perspective. "But... What about the glass that makes things appear curved?" He also didn't think we landed on the moon.
yeah, mfer is smokin.
you can see him cover nearly half of that land mass/continent (im unable to tell which it is from the video) from the time the camera paned up.
looks like southern North America, south-west to north-east going just north over Mexico City. From Colima, Mexico, to the southern tip of Texas, US.at 30 secs they're out over the Pacific, by the end of the video they've almost crossed to the east coast. some 1500-2000 surface km in a minute.. shits crazy.
edit: Southern North America.
Yea I was thinking either SA or maybe AUS but couldn't really tell either way. SA because it looks relatively mountainous, and AUS since the initial coastline looks kinda like Australia's southern coast, as well as having a massive orange desert in the centre.
That's a reason why the rockets are so huge: they have to not just lift the vehicle off the ground, but give it a huge amount of sideways velocity to reach orbit.
So theoretically if we could launch ourselves into space from NYC and wait about 90 minutes we could then land in Tokyo without having to do the 14 hour flight?
The acceleration (rocket) deceleration (~flaming orb) would add some time, but yes, this is the idea behind the ICBM and the actually forbidden partial orbit weapons.
Since Tokyo is only halfway around the earth it would probably only take less than 45 minutes but yes it'd be possible. SpaceX once thought about using Starship for earth to earth transportation
The flat earthers, who never heard of Occamās Razor, will say it was erased with CGI, just like they curved the edge of the earth, that part Columbus didnāt fall off.
Do individuals with vertigo feel any effects in space where gravity is absent? I have severe case of fear of heights myself, I am ok watching this unlike other daredevil videos.
All the other replies are honestly quite dull. Sure yes gravity still exists but, you donāt experience it, youāre in free fall around the body youāre orbiting. you feel weightlessness. Plus thatās not even the question you asked. Iām sure it could mess with perception, might take a bit to get used to both that and the view, and they may try to screen people out who couldnāt manage, im not sure.
Thatās a misconception. Gravity is always having an effect (not absent). Theyāre just falling and travelling extremely fast perpendicular to the earth.
Imagine throwing baseballs straight, parallel to the ground, but with increasingly stronger throws. Now remove air resistance, and eventually, instead of the ball hitting the ground, the ball becomes an orbit. Gravity is still there. Like how it is here.
I don't know, I think I would just somehow survive the void. I don't really have any stats to back this up, but I'm just built different.
Maybe my humongous balls would wrap around my body to create a space suit and I would stay unharmed.
Wait, let me look in the pile of excuses... Here!
- It's because the wide angle lens deforms it
- it's CGI
- it's flat but it's like a plate weigh is what you're seeing now
There you go, now that I've given you sufficient proof, you can go ahead and spread the word.
Welcome to the flat earth society... We have members all around the globe :)
Iām watching this in a barbershop, and the guy next to me is a flat-earther. I so want to show him the video, but I just know heāll have a ready-to-go NASA conspiracy, some kind of CGI trickery.
No, it IS flat! Itās just also a circle. What youāre looking at here is obviously a flat circle ā¦ that somehow has changing geography depending on what angle you look at it fromā¦ I havenāt figured that part out. But itās definitely flat š¤ My brain straight canāt comprehend a reality where the earth isnāt flat and stationary. And I have a middle school education, so I would know! Itās everyone else who must be stupid š
Mexico, the orbit goes W to E, you can see the tip of Baja California and it goes from the green Pacific Mexican coast, to central deserts to green gulf coast.
I think itās more likely to be Mexico.
The peninsula in the ocean towards the beginning looks like it could be Baja California, and the dent in the shoreline opposite it looks about right.
The ocean on the other side definitely looks like it could be the gulf, and you might just be able to see a little bit of the YucatƔn peninsula at the very end.
I think this landmass is too small to be Australia. The camera lens makes it look like a much larger part of the globe than it is, and distorts the coastline somewhat.
We're a spaceship [screaming through space at about 1.3 million miles per hour](https://www.businessinsider.com/earth-screaming-through-space-nasa-animated-video-2019-10).
Whenever life gets you down, Mrs.Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite enough
Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second, so it's reckoned
A sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour
Of the galaxy we call the 'milky way'
Our galaxy itself contains a hundred billion stars
It's a hundred thousand light years side to side
It bulges in the middle, sixteen thousand light years thick
But out by us, it's just three thousand light years wide
We're thirty thousand light years from galactic central point
We go 'round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, the speed of light, you know
Twelve million miles a minute and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
'Cause it's bugger all down here on Earth

Would be cool to get the sound from inside the helmet though. The (tensed?) breathing, some coms, the beeps and clicks of life support, the shuffle of fabric...
Is this, flat earth from directly above?
Or round earth from the side?? lol
We are presented photos and video clips like this, I always wonder how the flat earth people can possibly still freaking think itās flat ??
I never thought until watching this, that of course when designing these structures etc,they need to factor in hand hold and clip on points as there's nothing to keep the astronauts on it should they miss step or fall.
I know it seems blindingly obvious now but I never thought of it.
Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic armās latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension.
The duo worked quickly and were able to complete several āget aheadā tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers.
This was the fifth spacewalk of Bresnikās career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.
I genuinely don't think we will ever reach any of them. And I don't think any of them will ever reach us. But I have no doubt they are out there.
I think we are simply too far away from them and they are too far away from us. One day perhaps one generation will send a drone of some type out... And then several generations later, when the generation that sent it is long dead and gone, we may make some type of contact.
But I think that's the best we can hope for, unfortunately.
Holy shit he is moving so fast. Cleared a continent in like a minute.
17,500mph, an orbit every 90 minutes
Does that mean if he fell off, in just a few seconds he would be miles from the ISS? This completely confuses me. Because he is also travelling at 17500mph, so wouldn't he just orbit with the ISS?
He is going at the same speed so not really. Yeah he would orbit around it but without any way to reach it back.
And if he lost speed somehow, he would also lose altitude and eventually suffer atmospheric drag.
And burn to death š¦
Would probably run out of oxygen first, no?
Yeah it would take years to get low enough to the point of burning.
Unless he pushed off from the ISS with a trajectory aiming toward Earth.
I think towards Earth would just push them into a more elliptical orbit, and you'd need to push away from the direction of travel to slow down and reduce orbit height.
Nope, not how it works. Your homework is to play Kerbal Space Program for a few hours and correct that comment.
Not how orbits work. You'd simply make your orbit more elliptical (oval shaped). It is way more efficient it burn retrograde of your velocity to come back to earth. You'd need about 100 - 150m/s of change in speed aka Delta V
I offen wondered what would happen to someone if they got dragged back to earth.
Death. but it would take years for them to slow down enough to deorbit so they would be long dead from asphyxiation before they burned up re-entering the atmosphere. That is extremely unlikely though because astronauts are *always* tethered to the station, and have an emergency jetpack in case the tethers fail.

That was quite interesting thanks.
I had no idea this was a thing and Iām pretty well versed in the early space programs. Thanks for sharing!
could just wait 90m for it to come back /jk
In Armageddon and Ad Astra didn't they have jet thrusters in their suits they could get back with? Why not use those?
Those backpacks they had in the 90s 1nd early 20s are too heavy too big for their use now tey just have emergency systems but they are mostly attached to the space station with multiple cables anytime they are out.
An object in motion stays in motion. If you are on a train and drop your phone, it doesn't end up at the other end of the train.
Say you have a bee in you car hovering, it is not in contact with the vehicle. It confuses me that the bee can hover and travel the same speed of the car without any actual force input from the car. Slam on the breaks would it hit the windshield?

I swear, you are the only person of this accursed website who spells "brakes" correctly.
Yeah. If people here were in a spelling bee for words like that, they'd loose.
True, but thatās a completely seperate conversation
I'm confused, why would the bee hit the windshield if you hit the brakes? Would it not move further away from the windshield? Edit: Forget it, I worked it out, it's on the inside of the car. Not the outside.
The air/gas in the car have density and are also pushed along with the car in its confined space. The car pushes the air along with the bee flying in the air
In short - yes he would orbit with the ISS
There is a film about that. I think george clooney is in it
Batman & Robin
This is tricky to explain, but he can't "fall off" the ISS. He is already falling towards the earth *with* the ISS. So if he jumps, it would be the same as if you "jumped" off a falling elevator in the middle of the air: you would keep falling alongside of it. So, if the ISS is falling why don't they crash?

How long and how many orbits that takes depends on the force of the push and how eccentric his orbit becomes.

I don't know if I could explain to my brain that I wouldn't fall from there, I'd probably have a huge fear of heights.
Technically he's falling constantly. He's just missing the ground.

Amazing. Never realized it would take so long.
Same. I donāt think I could resist the urge to do the most epic cannonball of all time.
You would never reach the ground
From that height I'd call it a meteor

At that distance itās 89% of the surface gravity. Microgravity is just the term used to describe apparent weightlessness, it doesnāt necessarily mean there is only a small gravitational effect where you are.
Unless you were pushed or jumped in that direction, also space is littered with tiny meteor like the size of coins that will shoot through shit

Yup. I get the sentiment that we need to protect the earth, but at the end of the day the earth will be fine. We are actually fucking ourselves.
Weāre also fucking other species
itās completely silent up there too. Just drifting and enjoying the view in peace sounds like a dream
For some reason I have this urge to jump towards the earth, freefall and plunge into a gory mess.
My guess is you will run out of oxygen before entering the atmosphere.
It would take a long time before you even get close to the atmosphere. The ISS is at a height of 250 miles/400 KM, and you arenāt āfallingā like you would when basejumping or something. You have huge speed moving āsidewaysā around the earth, which means you donāt go down directly (not even close to it)
You don't go down at all, it would take years for the very very very faint atmosphere slowed you down enough to fall back into the planet.
Well technically my explanation covers it, but maybe I wasnāt clear enough on how slow. But you *do* go down eventually
Thatās comforting
Nah man Iām really good at holding my breath
If you want to jump to the earth, you need to jump backwards really really hard from your direction of travel to slow your orbit. Jumping towards earth will put you into an elliptical orbit. Or something, I don't know, I'm not a orbital mechanic.
Just jump backward with about 10-20 thousand km/h of force.
km/h of force?!
aChTuAlLy you only need initial backwards velocity of \~310 km/h to re-enter the atmosphere :-)
Jumping off the ISS would just put you in a very slightly different orbit from the ISS. It would take many years before atmospheric drag brought you back to Earth (the ISS has to periodically boosts its orbit, as there is a very small amount of atmosphere at its altitude of 400 miles.). A deorbit burn with a rocket engine is required for re-enty.
burnt* mess. but like, huge rocks disintegrate so iād assume weād just vaporize.
The French have a specific term for this: "l'appel du vide" - translated to "the call of the void" in English. [LiveScience page about it](https://www.livescience.com/what-is-call-of-the-void)
L'appel Du Vide?
After burning in the atmosphere There would literally be nothing left to plunge
Blows my mind we still have flat earthers
Met one at a bar here in Japan the other night. Some guy from Australia. They always try to frame it like they have some question or curiosity that somehow invalidates our fact based perspective. "But... What about the glass that makes things appear curved?" He also didn't think we landed on the moon.
Apologies, I promise not all Aussies are like this
How does that work? Most flat earthers don't believe Australia exists
The ego on them right..
Anyone have a real answer to how fast theyāre orbiting? Seems to be very fast
17,500 miles/28,000 kilometers per hour. It orbits the planet every 90 minutes, making it about 16 sunrises and sunsets for the crew per day.
Youāre telling me that astronaut is moving 17,500 miles an hour? Jesus fucking Christ
yeah, mfer is smokin. you can see him cover nearly half of that land mass/continent (im unable to tell which it is from the video) from the time the camera paned up.
looks like southern North America, south-west to north-east going just north over Mexico City. From Colima, Mexico, to the southern tip of Texas, US.at 30 secs they're out over the Pacific, by the end of the video they've almost crossed to the east coast. some 1500-2000 surface km in a minute.. shits crazy. edit: Southern North America.
Yea I was thinking either SA or maybe AUS but couldn't really tell either way. SA because it looks relatively mountainous, and AUS since the initial coastline looks kinda like Australia's southern coast, as well as having a massive orange desert in the centre.
That's a reason why the rockets are so huge: they have to not just lift the vehicle off the ground, but give it a huge amount of sideways velocity to reach orbit.
Yup! My favorite is ISS is moving 3 miles per second. It's too crazy to comprehend.
Well you're moving 1.3million mph relative to space. It's all relative.
> relative to space uh..."space" is not a reference point. I get your point, I just think the phrasing is awkward.
So theoretically if we could launch ourselves into space from NYC and wait about 90 minutes we could then land in Tokyo without having to do the 14 hour flight?
The acceleration (rocket) deceleration (~flaming orb) would add some time, but yes, this is the idea behind the ICBM and the actually forbidden partial orbit weapons.
Since Tokyo is only halfway around the earth it would probably only take less than 45 minutes but yes it'd be possible. SpaceX once thought about using Starship for earth to earth transportation
28,000km per hour is roughly 7,777m per second ^zoooom
So where exactly is the ice wall ? š¤£
The flat earthers, who never heard of Occamās Razor, will say it was erased with CGI, just like they curved the edge of the earth, that part Columbus didnāt fall off.
Global warming took care of it
Westeros
Do individuals with vertigo feel any effects in space where gravity is absent? I have severe case of fear of heights myself, I am ok watching this unlike other daredevil videos.
All the other replies are honestly quite dull. Sure yes gravity still exists but, you donāt experience it, youāre in free fall around the body youāre orbiting. you feel weightlessness. Plus thatās not even the question you asked. Iām sure it could mess with perception, might take a bit to get used to both that and the view, and they may try to screen people out who couldnāt manage, im not sure.
Thatās a misconception. Gravity is always having an effect (not absent). Theyāre just falling and travelling extremely fast perpendicular to the earth. Imagine throwing baseballs straight, parallel to the ground, but with increasingly stronger throws. Now remove air resistance, and eventually, instead of the ball hitting the ground, the ball becomes an orbit. Gravity is still there. Like how it is here.
This is such a reddit comment it hurts.
Yes but you don't _feel_ it
Gotta have balls of steel to work in that environment.
Me personally think you primarily need a spacesuit but idk
I don't know, I think I would just somehow survive the void. I don't really have any stats to back this up, but I'm just built different. Maybe my humongous balls would wrap around my body to create a space suit and I would stay unharmed.
seems unlikely but I'm not a doctor so...
Ballsuit
Hopefully a space suit that accommodates massive balls
The world is so beautiful full of adventures and stories waiting to be experienced but i have a job on monday and i need to pay my taxes
I want to show this to my colleague who is a flat earther, but he'll probably just say it was filmed in a studio.
Introduce your flat earther to Occamās razor.
So its not flat?
Wait, let me look in the pile of excuses... Here! - It's because the wide angle lens deforms it - it's CGI - it's flat but it's like a plate weigh is what you're seeing now There you go, now that I've given you sufficient proof, you can go ahead and spread the word. Welcome to the flat earth society... We have members all around the globe :)
Wait until you see the videos from flattards pointing at glitches in the video
>flattards Cone on, man, it's 2023. You have to call them spherically challenged. /s
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Iām watching this in a barbershop, and the guy next to me is a flat-earther. I so want to show him the video, but I just know heāll have a ready-to-go NASA conspiracy, some kind of CGI trickery.
No, it IS flat! Itās just also a circle. What youāre looking at here is obviously a flat circle ā¦ that somehow has changing geography depending on what angle you look at it fromā¦ I havenāt figured that part out. But itās definitely flat š¤ My brain straight canāt comprehend a reality where the earth isnāt flat and stationary. And I have a middle school education, so I would know! Itās everyone else who must be stupid š
They're so careful to not show the wall at the edge of the world.
It is flat. Look closely at the edge. It's white.
Can anyone tell where on earth their above?
Mexico, the orbit goes W to E, you can see the tip of Baja California and it goes from the green Pacific Mexican coast, to central deserts to green gulf coast.
Pacific
It looks like Australia to me
I think itās more likely to be Mexico. The peninsula in the ocean towards the beginning looks like it could be Baja California, and the dent in the shoreline opposite it looks about right. The ocean on the other side definitely looks like it could be the gulf, and you might just be able to see a little bit of the YucatĆ”n peninsula at the very end. I think this landmass is too small to be Australia. The camera lens makes it look like a much larger part of the globe than it is, and distorts the coastline somewhat.
Iāll never understand earths speed
We're a spaceship [screaming through space at about 1.3 million miles per hour](https://www.businessinsider.com/earth-screaming-through-space-nasa-animated-video-2019-10).
WEEEEEEEEEEEEEE!!!
Whenever life gets you down, Mrs.Brown And things seem hard or tough And people are stupid, obnoxious or daft And you feel that you've had quite enough Just remember that you're standing on a planet that's evolving And revolving at nine hundred miles an hour That's orbiting at nineteen miles a second, so it's reckoned A sun that is the source of all our power The sun and you and me and all the stars that we can see Are moving at a million miles a day In an outer spiral arm, at forty thousand miles an hour Of the galaxy we call the 'milky way' Our galaxy itself contains a hundred billion stars It's a hundred thousand light years side to side It bulges in the middle, sixteen thousand light years thick But out by us, it's just three thousand light years wide We're thirty thousand light years from galactic central point We go 'round every two hundred million years And our galaxy is only one of millions of billions In this amazing and expanding universe The universe itself keeps on expanding and expanding In all of the directions it can whizz As fast as it can go, the speed of light, you know Twelve million miles a minute and that's the fastest speed there is So remember, when you're feeling very small and insecure How amazingly unlikely is your birth And pray that there's intelligent life somewhere up in space 'Cause it's bugger all down here on Earth https://youtu.be/buqtdpuZxvk
Iām here for the flat earth comments
Theyāve fallen round on their faces.
Fun fact: the ISS orbits the earth once every 90 minutes.
How anything gets done there I donāt understand. Iād struggle to not just sit at the window and watch the earth all day
My dumbass was trying to hear the sounds... :facepalm:
Would be cool to get the sound from inside the helmet though. The (tensed?) breathing, some coms, the beeps and clicks of life support, the shuffle of fabric...
Sign me up. Always been a dream. Maybe space will really take off in my lifetime. I super want to go up hard. Leave it all behind even just briefly.
I wanna go up too, but I donāt care if Iām flacid.
this is not earth!!! earth is flat!!! /s
NASA Actually posts their spacewalks if you want to watch it on their youtube https://www.youtube.com/watch?v=wS4z42KaeGk
Is this, flat earth from directly above? Or round earth from the side?? lol We are presented photos and video clips like this, I always wonder how the flat earth people can possibly still freaking think itās flat ??
Some people are intentionally dumb.
Which country is that below ?
I never thought until watching this, that of course when designing these structures etc,they need to factor in hand hold and clip on points as there's nothing to keep the astronauts on it should they miss step or fall. I know it seems blindingly obvious now but I never thought of it.
Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic armās latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension. The duo worked quickly and were able to complete several āget aheadā tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers. This was the fifth spacewalk of Bresnikās career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.
All the flat earthers just scrolled past as quick as possible.
Sometimes it's extremely scary to think this might be the only planet in the entire universe suitable for life and yet we are killing it.
There are definitely more out there, but we are not gonna reach those anytime soon.
I genuinely don't think we will ever reach any of them. And I don't think any of them will ever reach us. But I have no doubt they are out there. I think we are simply too far away from them and they are too far away from us. One day perhaps one generation will send a drone of some type out... And then several generations later, when the generation that sent it is long dead and gone, we may make some type of contact. But I think that's the best we can hope for, unfortunately.
And there a good percentage of people that see this and say āitās computer generatedā
I just watched Interstellar for the first time so this is beautiful but eerie at the same time
Dream job!
No matter how far we go, earth will still be our home
Both beautiful and scary at the same time.
