Live to the end of the mission! Can stay forever! Because the body is in weightlessness in space, so many of the body will degenerate, the most important thing is the muscular system. Due to the lack of regular force support (the ground, the legs to support the weight of the body, often in tension, the muscles will be stronger), the muscles will gradually degenerate, the skeleton of calcium loss serious, and even lead back to the ground Can not walk after, need rest and exercise.
