Technically it’s just a bunch of metal and other stuff but the thought of deorbiting the ISS makes me sad.

That sounds like a classical OSI layer 0 problem.

I would guess that automated systems (especially jettisoning storage) would not be implemented as the gain is to low for the risk in case of a false alarm. There would always be someone reachable and awake in case of emergency to close hatches manually. Warming up the landing module could be interesting though…

I hope the expert will answer!

Oh. I didn’t know this was a thing. In my mother tongue (German) it is like a normal expression.

My quick guess is that it is so dim, that our eyes are seeing it mostly with the rods (instead of the cones), which only see black and white. „In the night all cats are gray“
