Making the project exceptionally unique is the fact that Scott's identical twin Mark, also an astronaut, will be here on Earth acting as a control subject for the experiment.

Researchers will be able to compare the identical twins' mental and physical conditions to better track the changes that are caused by being in space for such a long time.
