Scott Kelly spent a well-documented year in space, as his identical brother spent the same time here on Earth. The study was to determine the effects that space has on the human body. Both in the physiological sense and the psychological. What researchers have discovered so far is that Scott’s white blood cells grew longer than his twin Mark Kelly. The belief is that it could be linked to the body’s efforts to prevent chromosome deterioration. Further testing is being done to determine if there is a potential space gene that may have activated in Scott from his time in space.
This research will then help to support the future missions of people in space who are headed to Mars and beyond.
