I had recently re read portions of Col. Hadfield's book. He spoke of an unofficial rule of thumb that it takes a day back on Earth for every day in space to physically recover. He felt that was accurate for his 11-14 day Shuttle missions. For his 5+ month ISS assignment, he felt like it took forever to get "back to normal." I wanted to ask Capt. Kelly if during his recovery from 11 months in microgravity, did he feel like he ever got back to normal, did he just kind of accept that this was going to be his new normal, and did he really remember what "normal" felt like? With that thought, what were his personal opinions or reflections on longterm human viability in microgravity? From the physical point of view alone, not even considering, radiation issues, or mental and emotional concerns with long term isolation, boredom, and claustrophobia.
Yeah, a mouthful. I tried repeatedly to tailor it down to something askable in one question. So I was relieved to sit there and listen to him answer the questions: Are there a million buttons in the ISS? and How do you keep from bumping into things when you're floating in the ISS?
