bokonon, it is 360 degrees every 20 minutes/18 degrees per minute/3 tenths of a degree per second, or 1080 degrees/3 spins per hour. It is fairly slow. The PAO for Apollo 15 here(history.nasa.gov...);
"This is Apollo Control at 66 hours, 1 minute. Apollo 15, at present time, continuing at its Passive Thermal Control mode and the crew [are] about 4 hours away from the scheduled time of awakening. In the Passive Thermal Control mode, the spacecraft is rotating about its longitudinal axis at the rate of about 3 revolutions per hour to maintain uniform exposure to the Sun and the proper thermal control of the spacecraft."
I have no comment about the ISS. Optical subsystem B2, light transmittance telescope and sextant – as we said previously, the sextant was a very useful instrument as long as the platform was kept in alignment within plus or minus 0.9 degree. Then stars would be visible in the sextant and it was very useful. The telescope, on the other hand, was a very poor instrument because of the light loss through it, not being able to detect star patterns without a considerable period of dark adaptation. That's all I got on that.
000:53:35 Aldrin: Okay. Noun 71, we used 30 and 37; four balls 1; Noun 93, plus 00016, plus 00033, plus 00152; GET 00:48:15; check star 34. Over.
000:54:02 McCandless: Roger. Say again check star.
000:54:06 Aldrin: Check star 34.
000:54:09 McCandless: Roger. We copy. And the angles look good.
This is not bad about the red glasses, sure coulda' come in handy on those pretend Apollo ships....

They may have been sick. Their equipment may not be working. They were PERFECTLY COMFORTABLE ON THE MOON A MINUTE AGO, and now they feel so cold ? Why is that ?
When worn in normal illumination, red goggles will not interfere significantly with the ability to read most maps, charts, manuals, etc.,

I am a doc remember, and I brought the subject up, and just gave a reference that explicitly addressed your point/question, and again my question was choos , "Why didn't Charles Berry bring the subject up when he found out the Apollo ain'tstronauts had trouble with dark adaptation ? Why didn't the Chuckster recommend the red shades ? "
Google "Charles Berry, Apollo" and you get this;
Somewhat reassuring that the doctor is being acknowledged for his strong lack of effort and incompetence.
