After 340 consecutive days in space, Commander Scott Kelly’s return to normal activity on Earth will be gradual. Life in space takes a toll on the human body, changing a person’s eyesight, affecting memory and motor control.
A major part of Kelly’s mission is to help NASA get a better understanding of those changes so that it may find out what future astronauts might experience on the long journey to Mars.
