From NASA's press release:

"Kelly and Kornienko will spend a year on the space station to better understand how the human body reacts and adapts to the harsh environment of space. Data from the expedition will be used to determine whether there are ways to further reduce the risks on future long-duration missions to an asteroid and eventually Mars.

"The crew will support several hundred experiments in biology, biotechnology, physical science and Earth science -- research that impacts life on Earth. Data and samples will be collected throughout the year from a series of studies involving Scott and his twin brother, former NASA astronaut Mark Kelly. The studies will compare data from the genetically-identical Kelly brothers to identify any subtle changes caused by spaceflight.

"Padalka will spend six months aboard the outpost, during which he will become the first four-time station commander and record holder for most cumulative time spent in space."
