Imagine all that hard work, countless hours of studying and all those interviews and positions that thousands were applying for. These guys floating and having fun at the international space station. Mike, Satoshi and Sergei... Winners.
They're not in zero-G and they're not moving backwards. The space station is accelerating forwards (non-zero-G) while they stay still. Its akin to being on roller skates in train when the train starts moving - you stay still, the train moves.
This is a bit late, I know, but the socks are for a few reasons. One, they keep things kind of cool on the station due to all the computers, electrical equipment, and the sun minus 200 miles of earth's atmosphere heating things up. Also, there are velcro strips on the floor in various places where the socks will grab on and the astronauts can hold themselves in place, if need be. Also it keeps skin from clogging the air system.
@FIGHTTHECABLE Feasible, except that its impossible to reach light speed, the recoil from that rail would be killer to whatever it was mounted on, and you'd still need a gargantuan amount of energy to accelerate a spacecraft to a good fraction of the speed of light
@FIGHTTHECABLE There is the issue of recoil for sure. In space, there's no way to keep the railgun from firing itself backwards, unless you put rockets on the railgun to compensate, but if you're going to do that, you might as well have the rockets on the spaceship. Mass drivers, are, however a possibility for firing craft into orbit from the surface, especially from bodies such as the moon. The trick though for human space flight is having a safe acceleration, which such railguns may lack.
@FIGHTTHECABLE 'Fraid it's a simple matter of KE=0.5mv^2. It doesn't matter how you accelerate an object, you still need the same amount of energy to so. Bigger object or faster speed means more energy. And using magnets to accelerate the spacecraft wouldn't get around the recoil issue - that's Newton's third law.
So you're actually boosting back up in altitude so that you may re-enter "Free Fall" again giving the illusion that you are working in Zero Gravity. Got it!👊🏻
How cum they aint no strengs on that there viddeo? Everboddy knows they aint no space stashun! ;) But seriously, guys, nice job. I can only imagine how much fun you guys have up there when you're not doing experiments or maintaining the station in some way. As a favor to us space-believers, the next time you're outside, can you do a 360 degree slow-rotation of the camera on a couple of axis to prove that you're not in a vomit comet or a studio somewhere? It seems no amount of evidence is good enough for those guys, but it'd be nice to have anyway. JW3HH
Let the uneducated think what they want. If they think the ISS is not real, then what difference does it really make. Obviously, if they think that, then they are never going to contribute anything to society with respect to space flight anyway, so their rejection of it makes no difference. It would be a waste to spend one second trying to convince the unconvinceable of anything. Proof that it is not the vomit comet would simply be the fact that the vomit comet is only capable of simulating 20 or 30 seconds of weightlessness at a time. The fact that the clips are much longer than that is enough proof. So, there's that. Don't expect someone who believes the ISS is fake to accept it though. Again, they are going to reject what they are going to reject.
I wonder if it's possible to build a huge rail that you could fire ships into space, speeding the ships up on the rail to light speed. A Super fast Ship basicly. I think its possible since you don't have gravity. You would just need the technology and a laser beam. No return however, unless there another rail on the other end.
@atc90atc90 Anyone who goes in space as part of their work is considered an astronaut (or cosmonaut in Russia). They come from various professions and disciplines of science, as well as military. On the ISS each astronaut performs duties and does work based on their profession. The pay is good.
The boost was probably less than a minute, they're done by sending a craft up with as much fuel as it can carry (about enough for a minute or so after docking) and using the craft's engines.
At first I was like "Meh, so slow." Then I realized how spooky it is that the small tin can you live in is moving while you stand still in space... WHY THAT IS AWESOME?! Then neglecting the orbiting speed.
This probably IS a recircularization. KSP doesn't simulate a number of very subtle complications that make it necessary to reboost like this. The primary one is atmospheric drag. Sure, there's not a whole lot of atmosphere at their altitude, but they're going awfully fast and the ISS is god-awful un-aerodynamic what with those solar panels and all, so there IS a small amount of drag on the ISS that must be accounted for. In fact, when the ISS is out of sunlight, they usually turn the solar panels in the direction of orbit to reduce drag. Second is that the earth is not a sphere. It's a bit compressed from pole to pole, which changes the acceleration due to gravity throughout an orbit. Finally, there's the subtle irregularities in the earth's gravitational field that destabilize vehicles in low orbits. Mountains and oceans and all sorts of things can cause the gravitational field to change from one moment to the next, and that messes with orbits.
You would need a way of preventing a space-borne rail from shooting itself backwards. See Sir Isaac Newton's 3rd law of motion. Lunar based rails could work though.
I would get incredible annoying being stuck in a small spacestation with zero gravity for a long time, altough it would be incredibly fun in the beginning :P Being in zero gravity in a huge space where you can run and jump anywhere, now thats diffrent :D
@Scintillations314 Well how about it's mountet on a magnetic levitation rail. This means no friction. And the rail would only go for a certain distance, until the rail has reached light speed. And the Rail is in Space, so no gravity. Aswell, to guide the Spacecraft through space, there would be additional boosters. Who say's it need a lot of energy? LASER (Light Amplification by Stimulated Emission of Radiation) in pulses can move obstactles. Been shown in tests and is scientifically proven.
This kind of thrust should result in elliptical orbital trajectory rather than round. How you maintain correctly round trajectory with just one thrust? Plz explain.
like gelatinous said, it would be using two burns called a "hohmann transfer orbit" which essentially means you boost into an elliptical orbit, then boost at the peak of the elliptical orbit so you smooth it out into a circle orbit while increasing altitude.
@XRockVstarI499 The space shuttle has not escaped Earth's gravity. Imagine a cannonball being fired across a field at progressively greater speeds. Eventually, the cannonball would be going so fast that the curvature of the Earth would become a factor. As the cannonball sails across the surface of the Earth and begins to fall due to gravity, the Earth would fall away equally. This is exactly what is happening with the astronauts and their shuttle, given there are no causes for drag in space.
old comment i know, but it's literally the opposite. inertia doesn't exist as well on earth because air resistance slows things down. in space there is nothing to slow you down, hence inertia.
They're not moving, though. That's the thing. They're still inert. The space station starts *moving around them.* No feeling of acceleration like when you're in a car, because the car is moving you. Here, they're floating still and the space station is being moved.
Nothing went wrong here. Mike Fossum is an outstanding space walker and a great pilot. His Christian belief had no bearing on his ability to perform the jobs required of him during his tenure on the space station, and he performed them well. Perhaps you can present a logical explanation of why you think 'something went wrong' with a Christian being in space...
I think a scientist shouting "PHYSICS" while floating in a space station is a confirmation of everything good about human achievement.
Love the child-like joy of Satoshi Furukawa especially. :-D

What an awesome illustration of relative motion.
Thanks of posting!
It is nice to see that there is somewhere where everyone seems to get along and have a great time!
This comment aged like milk :C
Damn, that thing accerlerates nearly as fast as my '89 Ford Fiesta!

some additional facts would be great.
duration of the boost, delta-v, and the amount of fuel they used e.g.
OK... what module are you starting in and then going into?
Nevermind... i found it!
@FIGHTTHECABLE Feasible, except that its impossible to reach light speed, the recoil from that rail would be killer to whatever it was mounted on, and you'd still need a gargantuan amount of energy to accelerate a spacecraft to a good fraction of the speed of light

Every time i watch one of these I feel so left out in a whole different realm.
@@benjaminmateles1353 lol this comment is 9 years old and I don't even remember what I meant by it
@SerSyn where are they gonna get those on the ISS? :P
Color me subscribed. I love seeing this kind of footage. Blows my mind that we have people floating around in freakin SPACE.
That's amazing. I do it again. Wooooow.
@FIGHTTHECABLE 'Fraid it's a simple matter of KE=0.5mv^2. It doesn't matter how you accelerate an object, you still need the same amount of energy to so. Bigger object or faster speed means more energy.

Fun! It must be a strange feeling to experience any acceleration when you're used to none at all.
Would like to see their reaction with a big boost :)
So you're actually boosting back up in altitude so that you may re-enter "Free Fall" again giving the illusion that you are working in Zero Gravity. Got it!👊🏻

The problem is, you'd need humongous velocity, and things tend to burn to a crisp when they go that fast.
how did they post the station?
How often do they reboost?
@atc90atc90 Anyone who goes in space as part of their work is considered an astronaut (or cosmonaut in Russia). They come from various professions and disciplines of science, as well as military. On the ISS each astronaut performs duties and does work based on their profession. The pay is good.
How long was the boost? And did the astronauts reach terminal velocity?
The boost was probably less than a minute, they're done by sending a craft up with as much fuel as it can carry (about enough for a minute or so after docking) and using the craft's engines.
At first I was like "Meh, so slow." Then I realized how spooky it is that the small tin can you live in is moving while you stand still in space... WHY THAT IS AWESOME?! Then neglecting the orbiting speed.
What's with the Exit sign? Lol
@Nojaru Space has no gravity, only those of the planets and suns. But the rail is IN SPACE!
Sergei looks like hes having a blast!
give me more of that Asian guy just drifting around lol
Do they reboost again on the other side of the planet to re-circularize the orbit like in a Hohmann transfer?
This probably IS a recircularization. KSP doesn't simulate a number of very subtle complications that make it necessary to reboost like this.
The primary one is atmospheric drag. Sure, there's not a whole lot of atmosphere at their altitude, but they're going awfully fast and the ISS is god-awful un-aerodynamic what with those solar panels and all, so there IS a small amount of drag on the ISS that must be accounted for.

Imagine doing that while accelerating to near-lightspeed.
I want a screensaver of these floating guys!!
They didn't get acceleration, the station is moving but they are not
@DavidBlaine18 Being weightless would never get old man.
So little gravity, so much fun. You guys missed that!
Why do you wear socks? Seems like the extra exposed digits would be useful. I pick things up with my feet daily.

1) Become astronaut.
2) Perform somersaults in space.
They must be really bored up there to get this much joy out of it haha Wish I were there!
@anotherdupeaccount excellent thought...
They just keep going faster and faster!
They are not moving but it looks like they are. MIND FREAK!
so this is what they are studying to for years?
Great vid :)
0:28 wow.......wow......WOW.....WOO!
And none of them was doing the superman?!
This kind of thrust should result in elliptical orbital trajectory rather than round. How you maintain correctly round trajectory with just one thrust? Plz explain.
Probably two burns, a perapsis burn and a stabilizing apoapsis burn (the apoapsis would technically become the perapsis though)

Very cool
Well … it's kinda obvious that the space ship is moving - but not them. D'uh!
they seem to have fun :D
Love the Ooooo's. :D
INCEPTION
Gosh that must be soo fun
i thought zero gravity cancels inertia
old comment i know, but it's literally the opposite. inertia doesn't exist as well on earth because air resistance slows things down. in space there is nothing to slow you down, hence inertia.
You can also do this if you go to school ;)
They should do Halloween version in superman's costumes.
"Physics!" C:
MAY 27, 2016 :) sooo curious about OUTER SPACE! :D i want to experience :'(
NASA: sends astronauts into space in a multibillion space mission
Astronauts on a multibillion space mission: Physics, lol :D
@XRockVstarI499
Inertia in no way depends on gravity.
i want to do it
These guys have been out of the gravity well a little too long.
It's called falling.
Climbing is pretty easy up there!
i wish i was there..
space. space. wanna go to space. wanna go to space. wanna go to space. Space. Space? SPAAAAAACCCCCCCCCCCCCEEEEEEEEE!!!!!!
Gravity=acceleration. There is not really a difference between those things.
I WANT A GO :'(
Maybe one day, eh?
@HazenHills Not the same.
lol it totally looks like they blazed like mad before doing this XD
Everybody has a little kid inside! :D
0 dislikes? This is rhinoserous!
La NASA non dovrebbe affidare rocce lunari senza le dovute precauzioni.
It would then fall straight down.
Thats what you do when you go to space😅
lol they're in the space in a zero gravity space station and they're having fun with moving backwards????
They're not moving, though. That's the thing. They're still inert. The space station starts *moving around them.* No feeling of acceleration like when you're in a car, because the car is moving you. Here, they're floating still and the space station is being moved.
One of them is an undercover asian that just wants their launch codes. Guess which one.
they need to work on cupboards for that thing!
@FIGHTTHECABLE
There's always gravity
I love how much fun the asian guy is having
is it only me but aren't astronauts really cool guys?
"physics!"
Cannonball...that empty space guys
1:40 is the best scene! :D
LMAO
i would never get bored of doing that hah

wow wow wow
WOOOOOW
wish i would b there... :)
haha I'd consider moving at 17000 ks an hour pretty noteworthy.
That really looks like fun! hahaha!!
Lol, Astronauts living in zero G think accelerating is noteworthy.
