The Earth-bound Kelly brother is taking part in experiments as part of his brother’s yearlong stay in space. Scientists hope to use data collected from each of the Kelly twins to learn more about how a long stay in space can affect the human body.
"We will be taking samples and making measurements of the twins before, during, and after the one-year mission," Craig Kundrot of NASA's Human Research Program, said in a 2014 statement. "For the first time, we'll be able two individuals who are genetically identical."
Scott Kelly’s space station mission marks the first time an American will spend a year in space. He and Russian cosmonaut Mikhail Kornienko will spend about 12 months on the station in order to help scientists learn more about long-duration spaceflight and even get to Mars one day in the future.

Earlier research has shown that astronauts can lose muscle mass and experience other health issues while in space if not mitigated correctly.
