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:

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".

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.

[@theeclecticdragonfly6912]

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.

[@ThunderWorkStudioAMGE]

He was the one who made the video, if we are talking about the same one.

[@theeclecticdragonfly6912]

I wouldn't be at all surprised.

[@TheAechBomb]

I'm not sure that's hubble, but let me go find the video

[@thundercactus]

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.

[@KohuGaly]

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.

[@nagualdesign]

I'm curious, what effect does all this manoeuvring have on all the microgravity experiments?

[@MegaKopfschmerzen]

That's why it's microgravity, instead of zero gravity

[@YounesLayachi]

What kind of question is this

[@nagualdesign]

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.

[@user-pb4hh1jk3f]

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.

[@nagualdesign]

@@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.

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.

[@D3emonic]

@@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.
