This can trigger considerable bone tissue and muscular tissue wear and tear, along with Nasa saying that astronauts might drop around 1 per cent of their bone mass each month in crucial locations including the reduced spinal column, hips, and also thigh.Presently, Nasa is dealing with emergency plans to restore both astronauts to The planet.
