Does anyone have a projection of the ISS ground track, with the shadowed/unshadowed bits of Earth, during a high beta angle time? Or perhaps an animation?

Another interesting similarity between life on a space station and life in Antarctica (often used as an analog for reasons of isolation and confinement): sometimes the sun doesn't set.

A couple of times a year our orbit line precesses to align with the solar terminator. When that happens, the sun appears off our port or starboard side and never sets. This lasts for 3-4 days and puts significant thermal stress on the spacecraft (constant heat or constant cold).
