Answer 1

About 90 minutes per orbit.

if you want to find out exactly when it is visible from your location (generally this is about once per week or 2 for any given location in the mid latitudes, for just a few seconds per occurance)

Answer 2

There is only 45 minutes of night, even less without twilight, and it takes 30 minutes to dark adapt fully. I doubt they ever turn off the lights there also (or maybe they do??).

But if you wear an eyepatch at the right times you might get a good half-hour in the dark, dark adapted.




Plus it's space. As long as you can avoid seeing the Sun, Moon, lit Earth, or have any part their light shine anywhere in the room then you're fine..
