...here's another interesting experiment they are allowing us to know about:

His brother Mark is also an astronaut, now retired. While Scott, the test subject, spends one year circling Earth at 17,000 mph, Mark will remain behind as a control.
"We will be taking samples and making measurements of the twins before, during, and after the one-year mission," says Craig Kundrot of NASA's Human Research Program at the Johnson Space Center. "For the first time, we'll be able two individuals who are genetically identical."
The experiment harkens back to Einstein's "Twin Paradox," a thought experiment in which one twin rockets to the stars at high speed while the other stays home. According to Einstein's theory of relativity, the traveling twin should return younger than his brother—strange but true.
