They have radiators to dissipate heat. And all the required systems to make that work like coolant pumps, as well as heat sinks (or the coolant fluid is the heat sink).
But they also have heaters, to make sure that (especially the batteries) don't freeze.
Satellites hang in a delicate balance between freezing and overheating.
I know as little as you do about selfhosting, but I just want to point out, if ip a generates a convoluted/confusing output, I would recommend using hostname -I instead. It just prints out all your IP-addresses, with no additional info.
There were some ideas to use it in rockets, but, as John D. Clark put it:
> It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water—with which it reacts explosively. It can be kept in some of the ordinary structural metals—steel, copper, aluminum, etc.—because of the formation of a thin film of insoluble metal fluoride that protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.
There were a few successful test fires with a CTF rocket on the ground, but to avoid explosions they had go through an elaborate multiple hour long cleaning procedure, and it ended up being too expensive and dangerous.
EDIT: At least using the web app, the first link is relative, and the others are not. So I think the correct format would be /c/<community>@<instance> for communities outside your instance.
