[Haichuan Tea House] Will rust occur in outer space?
Thread Content
This is a picture of a space station. What is the yellow mark on the back of the astronaut? Does outer space also rust?
There is no oxygen in outer space and it should not be oxidized.
Although outer space is a vacuum, it is not necessarily an absolute vacuum. There may be various gases or dust escaping into space, floating around, and encounters are also possible. Personal guess, no basis: lol
So what is causing that yellow patch? ? Are the astronauts cooking inside? ?
Could it be a mimic color? ? ?
It's probably not rust. For the high-alloy steel used inside, rust prevention should be a basic function. Is it caused by local overheating?
Well, your inference makes sense, and the problem of local overheating and oxidative discoloration is back;P
Guess the yellow one is the cabin door, which is on the outer layer of the spacecraft and is baked at high temperatures when it passes through the atmosphere.
