This may trigger notable bone as well as muscle mass wear and tear, along with Nasa stating that astronauts may shed around 1 per-cent of their bone mass every month in crucial places including the reduced spine, hips, and thigh.Presently, Nasa is working on emergency programs to revive both rocketeers to The planet.
