How the Space Station Moves In Orbit Like A Spaceship

- Many people don't realise that the International Space Station is also a space ship, able to maneuver in space as required by mission operations. It has thrusters and control moment gyros to control its orientation and adjust its orbit.
I could have explaind this with CGI, I could have used KSP
Instead I decided to use my LEGO model of the ISS as a prop:
The LEGO ISS is available on Amazon and other online retailers.

As a Canadian I love hearing Scott call the Canadarm the Canadarm rather than "the robotic arm"
It was smart of them to build something where the name of the country was in like every shot of the shuttle payload bay. Go figure Canada's biggest space contribution was a giant space hockey stick.
I feel that we know so little about DEXTRE.
@@GeneralSeptem while I get the joke, its a really complicated and amazing piece of tech. This iteration is more like we figured out how to attach the arm to the hockey stick and send it to space. And sent some shoulders ahead of time. 😂
As a german that sounds a little like a joke as "Darm" means intestines.
Canadarm and Canadarm2 (the one on the ISS) are such incredibly important inventions. Advanced robotic surgery on earth would never have been a thing if not for innovations made when working on the arms.
I'd love if Scott did a full video on them.
Old joke: when a famous admiral arrived on the bridge, he would unlock a drawer, take out a piece of paper, look at it, put it back and relock the drawer. He died unexpectedly and the first thing his subordinates did was open the drawer. The piece of paper said "port is left, starboard is right".
The reverse side of the paper read "When in doubt, Full Ahead out".
Heh... I heard this same joke but for accounting. The paper said "debits on the left, credits on the right."
An easy way to remember which is which is this:
The shortest words match up!
i.e. port has fewer letters than starboard
left has fewer letters than right....
My father's cousin was an old guy at the time and a big time drinker. He told me that the way to remember what color port and starboard lights were was to think of port wine. Port wine is red and thus starboard was was green!lol!
@@glenkeating7333 :-) I was taught a variation of that - drunk sailors get left in port
Commander: “Brace for turbulence.”
Crew: “Sir we’re in space.”
Admiral Adama: “No listen to him.”
hahahaahahaha nice one
@@linecraftman3907 I wonder if everyone on the ISS was tilting back and forth in their chairs while looking at a static laden view screen. Scotty, more power!
@@bobroberts2371 and then the terminals start sparking and someone falls over with third degree burns.
@@cosmicrider5898 Only the red shirts. And don't forget pipes falling from the ceiling and lots of steam.
@@bobroberts2371 And rocks :)
Scott just elevated himself to a god-like being
He can push the ISS with his finger against vacuum!
Just?
Everything is relative.
I posted the following in his vid " Measuring the Distance To The Moon Using Only A Smartphone Camera "
Scott said " I've asked all of my followers to . .. . " So Scott is the supreme leader of a cult? I knew that red robe was part of his leader regalia not an anomaly. I've uncovered the secret call to order chant " Children Of The Sun , by Billy Thorpe " See the vid " Billy Thorpe - Children Of The Sun (Exclusive Video) " on the channel " Sandman368 Video-Variety-Channel "
A very manly god-like being.
So the Kraken attacked the station in 2009? They should have checked their auto struts..
Danny could have spagettified the station AND ended the universe.
Bloody Karen's everywhere!
lmao i'm death
xyz Kraken, not Karen... Kraken is much more horrible and you will know if you play ksp
Not gonna lie if I was on board while that was happening the force of me shitting my pants could've raised the orbit all by itself
I like how Scott emphases *Fly safe* as the 420 tons space station hurtles through space at insane speeds, dodging specs of paint with the same power as bullets.
Less power, per se, but way more kinetic energy than most bullets. The damage that they could do would also be significantly more, depending on relative velocities.
@@Phroggster it works in our favour that they are moving so fast. Small debris gets turned into plasma the moment it hits the outside whipple shield. Slightly heating the outside of the spacecraft but not penetrating further.
Nice
@@lmaoroflcopter HOw big object in orbit should be to destroy station
@@dzonikg Scott has done a really good video on it. Recommend watching that one.
0:40 "I can now justify why lego is on my buisness expenses"
So it’s a spaceship with utterly awful propulsion, the way an oil rig is an utterly awful jet ski.
😆
Well, if you put the oil rig in orbit, a few jet ski engines would probably be just about adequate for attitude control and orbital corrections.
But it would still make an utterly awful jet ski, in the same way that the ISS is an utterly awful "spaceship".
Physics is a harsh mistress, but we like dancing a fine line around her when it comes to aerospace stuff.
More like a rather heavy space caravan that needs to get towed (pushed) periodically to keep it in the field (in orbit).
Some oil rigs are affixed to the sea bed.
@@gojewla which makes them even more like the ISS; putting either of them exactly where you want them requires a great deal of power, precision, and patience.
If anyone needs a stock photo of Scott to use in an article or something, just pause at 8:13 and take a screencap. LOL
Perfect

@@mistresskimberly326 shut up bot
To anyone who watches 'The Expanse', remember the expression 'a beer can with rockets strapped to it' ? In space, everything is a space ship if you have propulsion.
If I remember correctly Skylab had three large reaction wheels (non-gimbaled gyros) - one on each axis - which NASA used to orient the station. Unfortunately it took a command/service module (CSM) to raise its orbit. If they hadn't used the last CSM on the Apollo-Soyuz mission perhaps it could have been used to boost Skylab high enough to stay in orbit until the Space Shuttle finally flew.
I would like to see a dedicated video by Scott about a relationships between ESA, NASA and Roscosmos and other space agencies.
Here is what I am interested in:
How and why decisions are made to plan and execute missions.
How arguments/different intentions between agencies are being handled.
How does finances work to run this project.
Who has a final/strongest say about ISS.
And so on.
Thanks.
All that might be covered by the Space Station Intergovernmental Agreement (IGA); a web search gives more info about it.

@RocketSurgeon thank you so much for the correction ❤️
Is there a video about that? sounds like excellent trivia to just...know.
Or the actual dog toy that people use as a dildo
8:10 "might adjust from its normal orientation"
Scott might want to think about what his hands are saying when he's using his hands to talk.
I have a feeling Scott made this video just to flex his ISS Lego model
Why does "Fly Safe" sometimes sound like a threat? lol
look up Eve Online, one of his past-times. ;-)
8:13 Anyone else catch Scott Manley flipping the bird off at us!! Lol Well played Scott, well played. Haha
I was looking for comments like this lol
6:50-7:12. Soft dock followed by rotational alignment and hard dock. I've never seen the rotation before. Makes sense of course since the vehicle interfaces must line up. Cheers Scott for posting that.
Watch from 6:40.
What follows should be prefaced with "If I recall correctly..."
I remember seeing a video quite a while ago talking about why the bearings failed on the Hubble and the early reaction wheels on the station. They were made of metal balls running in metal races. With the radiation and electromagnetism they experience on orbit, there would occasionally be static discharges from one component to another causing micro-welding and pitting of the balls and races. After some time in use the pitting would get so bad that the bearing would fail.
The problem has been solved by replacing the metal balls in the new bearings with nonconductive ceramic. No more arcing, no more micro-welding. And no more problem.
He was the one who made the video, if we are talking about the same one.
I wouldn't be at all surprised.
I'm not sure that's hubble, but let me go find the video
The issue was the manufacturer of those reaction wheels was also the lowest bid. Any millwright that's been around long enough can tell you what happens to the bearings in a piece of equipment when a welder puts their ground on the other side of a bearing and starts welding away.
It's possible they didn't understand that EM interference could cause static discharges within the spacecraft, or they didn't bother looking into it.
But the solution was upgrading to ceramic bearings, which aren't actually purpose built for that specific task, but are in fact industry standard bearings that aren't that much more expensive than steel bearings.
Small correction. The problem hasn't really been "solved". They switched to ceramic bearings before the metallic ones even started failing. It's just a happenstance that the new ceramic ones do not have the welding problem that was later discovered in older metallic ones.
I’ve heard the opening quindar tone check conversation to this channel before. It was Houston testing the global phone line/ long wave radio communications hardware with one of the repeater stations in Australia used to broadcast out to the Apollo spacecraft.
The radio operator in Houston would simply say to the station in Australia, “1-2-3-4-5-5-4-3-2-1 end of test”‘with a quindar open tone/close tone between each number.
Thanks Scott - now i know that ISS can fly safe and how :)

Thank you Scott for explaining this. It just so happens that my kids and I were researching how the ISS adjusts their altitude and attitude for their science class. You rock!!!
" These 'little things' (the Control Moment Gyros) are steering a 420 ton space station..." and by the way, this space station is racing around the earth at a speed of 27,576 km/hr....
And a single SSRMS(Space Station Remote Manipulater System aka CANADArm-2) while not being strong enough to hold itself up on the surface of Earth against its own weight, is strong enough on-orbit to fully manipulate the position of the entire almost 1 million pound ISS.
The complexity of orbital mechanics and space stuff in general is truly mind boggling. So many things to take into account, and it’s hardly automated, someone just had to think this through. I’m genuinely shocked every time I learn something new and wonder about the realities of commercial space flight which needs to be almost entirely automated.
Great video as usual
This is one of the most interesting piece on the ISS, I’ve learned many new facts, thanks Scott.
About the debate if it a space ship or not, this is my check list comparing it to a cargo seafaring ship:
1) go about the surface of the Earth in space or water, check
2j can change course and speed (slowly and carefully), check
3) can perform docking, check
4) transport goods and people, check
5) have sides identified as port and starboard, check
6) everybody (except FEer) believe it exists lol, check
7) Lego makes models of it, check
HEY it’s a “space”ship.
Oh my, the piping must be a pain if they move the propellant that far
Thanks Scott. I didn't realize how maneuverable the ISS is. I thought it just hangs there in orbit. Great info!
6:50 TIL that turning off the SAS during docking to prevent attracting the Kraken is legit in real life too.
Awesome vid. Reminds me of the opposite forces my gyros felt on my submarine that fed momentum to navigation. Well done m8t.
Starship will be as big, it can even serve as a space station
Yeah the ISS will be docking to Starship lmao
This video is very appropriate right now.
"NASA always has its plans figured out" can I get that on a t shirt? Lol
How fun. Another fantastic episode Scott! Fly safe
So, more Lego, but the Saturn V is still in wrong position. (The black dots should be faced to the LUT).
Not to mention a fake LUT that’s a scam...
I had no idea how big the CMGs were until you showed the shot of the spare with an astronaut. They are big!
„let me show you it’s features“ ... missed opportunity
This was awesome, I was on the Oculus Quest with Mission: ISS looking at the parts and hearing Scott describing! what a delight.!
I'm curious, what effect does all this manoeuvring have on all the microgravity experiments?
That's why it's microgravity, instead of zero gravity
What kind of question is this
Microgravity experiments are usually performed in a free fall environment, where the apparatus is subjected to weightlessness, but there's still a small gravitational gradient; the parts that are closer to the Earth are pulled slightly more than those further away, inducing a small tidal force. That's why we say "microgravity" and not "zero gravity"; they're still in a gravitational field.
The point of my question is because during manoeuvres, especially when using the larger thrusters, weightlessness is lost and, like the camera shown in the video, things begin to fall. That will have a small but not insignificant effect on any ongoing experiment.
They can't get out of small accelerations during burns, so they just have to take that into account with their data or (if possible) not perform experiments during burns. Luckily the burns are low acceleration and don't last long compared to the duration of the experiments. Some of the scientific payload racks have a device called ARIS which robotically cancels vibrations, so the experiment at least won't be perturbed by dockings, astronauts using the exercise machine, etc. if a group opts to get their experiment installed in one of the locations where that's available.
@@user-pb4hh1jk3f I see. Thank you for that. I guessed that they'd keep detailed logs of any accelerations, however small, which they could cross-reference when looking at the results. I wasn't aware how they kept their experiments isolated though. That's quite interesting.
Cool username, by the way.
Love the SA Corey (Expanse) books on the shelf in the background.
Last time I was this early starhopper was about to fly
I just searched this topic two days ago !!!! And now your video ??? Awesome luck for me ! Well done mate.
I've tried this with noodly KSP craft. It never ends well. XD
Fuck man.... I remember when watching you like 6-7 years ago on your brilliant ksp series... .basically learning all the interesting stuff from you... and look at you now where you got with your channel. Congrats man, happy for ya! :)
Does the Space Station flex a measurable amount when maneuvering? I imagine it's designed to be very stiff
It is probably measurable, but still insignificant in most considerations
When the resonant vibration took hold, it’s flexibility was challenged.
Awesome video. My Dad told me 'no red port left in the bottle' so I could get colour of the boat lights correct. Later I added that 'starboard' is a bigger word than 'port' and 'right' is a bigger word than 'left'.
Mission control can just terminate any debris that would pose a threat to the staton
Yeah why don’t they just delete them from the tracking station smh
@@Astro1tu r/woosh
@@Astro1tu no no you just delete the log entry in your computer database. Problem 'solved' 👍
I love how many people dont get the ksp rwference
You have to be playing SR2
Excellent, excellent video Scott Manley, you are truly the man!
A quick question, is there an astronaut designated "Pilot" on board at all times who makes the ultimate decisions when the station needs to be 'flown' or is everything so automated that would be redundant?
I think it's the control room guys on the earth, who decide that no? They have all the necessary information about the orbit debris etc...
There is always a designated commander who has final say. While most such decisions are made by ground control, it's important to have someone actually on the space station who is in charge.
@@stevens8354 Yes I'm aware of that, what I meant was the ground control has more information and manpower to analyze the information about ISS and the earth's orbit that it seems logical to me they are the ones calling shots on what has to be avoided and how, and controlling the engines. I'm not even sure if the station has it's own way of detecting the debris... (though I wouldn't be surprised if it had).
@@stevens8354 yeah, that's what I assumed, I can envision a couple scenarios that would require a designated person in control.
Best videos on the tube by far. Keep them coming. Thanks
14:30, i guess they forgot to check their staging?
While you were describing things and showing the orientations using the Lego model, I flashed back to the film (and novel) of Arthur C. Clarke's _2010: Odyssey 2._ The general design of the Russian (Soviet?) spacecraft in the film is similar in many ways to the ISS, while the Discovery is more like the Apollo designs.
Thanks as always for the interesting content!
Important question: have you ever sat down and played with this? like, pretended to dock the shuttle or anything? cause I would hands down do that
Pft.... He simulates a docking every night
That ATV looked badass.
WAIT is the lego ISS a set?
Link in the description
The docking procedeure is very reminiscent of how I dock in KSP. Always disable SAS right before contact, and make sure one of the spacecraft is just holding attitude.
Kinda makes you wonder how Sci-Fi stations like Starfleet Earth Spacedock work...
By the Power of Plot!!! And a lot of handwaving :)
How happy he is, while showing off his toy :)
[On opening up the Control Moment Gyros that were returned from orbit, and finding bearing fused from heat...]
"That's just a sort of great illustration of the amount of energy and force that is going on inside these CMGs..."
To me, it's a great illustration of the failure to lubricate adequately!

scott, i love these kinds of videos. nuggets of trivia that are infinitely interesting and you organize them together in a very fluid way.
Bloody hell! Sounds like rocket science! Very interesting.
MechJeb loves to resonate my ISS to pieces!
Very bold of you to hold your ISS and rotate it around with confidence. I'm terrified of mine falling apart just moving it from one place to another...
A dedicated space tug is needed. Without one, these guys will never make warp.
Absolutely fascinating- thanks Scott
Scott i love your use of the lego model. Once i saw you using your i grabbed mine and was able to follow along.
Coincidentally my coworker and I were discussing this yesterday lol
Actually we were curious about how they pump or distribute fuel threwout the ISS. We figured it must be always a nail biting experience
The main reason why experiments are stopped during maneuvers is because they require microgravity, which is the whole point of doing experiments on the ISS. Microgravity is obviously lost for the duration of the maneuver.
Fun fact: ATV could not refill the Zvezda module's propellant tanks because they used a different type of hydrazine and the two were not compatible.
Hey Scott! PLEASE consider doing a video explaining the recent Vacuum Raptor engine that was tested and why its kind of crazy to not test in a vacuum.
Also with the recent revelation regarding more water on Mars, why don't we just send a massive solid steel ball on a collision course with Mars and see what it leaves behind after the impact? It seems we'd be able to detect plenty with the spacecraft in orbit.
Best part of my day is learning interesting tidbits from you Scott! Thank you!
Really great explanation on the inner workings of the ISS...I learned more with your video than from any other source I've found. Thanks and keep up the outstanding content !
Great video, Scott. My understanding was that they desaturate the momentum wheels in a different way that's 100% renewable, by using the tidal force of the Earth. Basically by putting the station at an angle wrt Earth-downwards, so that the tidal force wants to turn it vertical, and resisting the turning with the momentum wheels, obviously choosing the direction such that it desaturates the wheels.
That's part of momentum managed mode, ADCO have tricks like that to balance everything out.
3:05 "some god-like force pushing it"
Guess Nauka gained divine powers while waiting to go to space.
This was a fascinating video. I'll think of it whenever I see the station fly over. Scott's posts are so filled with interesting information.
Very interesting, I like the use of a prop in this video
There is another thing that happens to spinning metal masses in space. There is a magnetic field in space. When a conductor moves through a magnetic field either by spinning or flying through it induces a voltage. The voltage potential wants to discharge. The only path is through the metal of the bearings. This causes an arc welding effect that pits the bearings and makes them run rough.
Very interesting and informative video. thank you Scott.
The thrusters firing at resonance frequency is crazy....wow
I am perpetually amazed at the realization of how empty my life was before I discovered Scott Manley. And I was a social cat who was in several bands before then... But Scott makes my brain feel loved.
"I'm on an All Terrain Vehicle Bob. It can go on ANY terrain! Oh, crap, I gatta go bob, apparently space is not a terrain."
Loved this video Scott :)
Where else would I learn such things! Thank you for compiling all this. I even brought my son to come see all your Lego builds.
I love that Scott flips everyone off in every video. Haha. 8:12
This is an interesting one, thanks.
3:05 Scott as some godlike being 😅
Hey scott, I teach sailing and here's a trick I use to help my students keep track of port and starboard!
You can remember it easily, because:
"port" has the same number of letters as "left"
and
"starboard" has the same number of letters as "rrigghhtt"
... I should have mentioned I teach sailing to 8-12 year olds :P
very clear explanations. thx. subscribed
I love how the model playing with the ISS on the Amazon page is a grown man.
I would love an episode going more in-depth on how gyros work for spacecraft. Why do most spacecraft use thrusters for rotation instead of gyroscopes? Wouldn't the lack of required reaction mass be a massive boon especially for long-term missions?
Its over already? Never thought about any other maneuvers that ISS perform than rising the orbit! Damn Scott I could listen to your lectures for hours!
Thanks , for answering my question, nice video .
