    She's a good tour guide. Appears to speak Russian, that's useful too. It sure would be important to get along well with people up there. And to have a well functioning digestive tract, seeing how the bathroom works.

    I'm so envious of the floating! I have a spine problem that prevents me from being on my feet for too many hours at a time, and floating in water is heaven for me. Floating in space would be even better! The bone and muscle mass problem is a very real one though, I have to work at that too. Isn't that cool how the exercise equipment is engineered to avoid jostling the station itself.

    We love watching the ISS go by. This time of year it's iffy, because of cloud cover. Summer is great in the PNW for that.

    •  One of the astronaut complaints is back pain. (1+ / 0-)

      You might not feel better after a while. After prolonged periods of no weight, their discs get a little enlarged causing chronic pain in some.

      Earth's gravitational force compresses our spines; we do not sense the compression because we are used to it. But in microgravity settings this compressive force is no longer present — and our spines stretch! Astronauts actually grow 2 to 3 inches taller (5 to 8 centimeters) when they are in space! The stretching can cause them some pain; many astronauts have back pain while they are in space and the stretching can potentially injure nerves.
