I can’t wait to read all of this. Scott Kelly is so facinating. Just imagine what he had to go through while being away from earth. And as I was reading this, I thought of just how intense his training for it all had to be. I can’t imagine the psychological effect. And what about when you return? Wouldn’t your joints hurt because there’s no gravity in space. I’ve heard you get smaller. Would the joint pain stay for good like arthritis or be a passing thing? As a lab tech, I wonder how this affects the blood. I would love to test his. Would his calcium and bone density be changed?
