    Next year, with the assistance of the world's only twin astronauts, NASA will conduct an unprecedented experiment in human biology. While one twin remains on the ground, the other will circle Earth onboard the International Space Station for a full year. Will the twins still be identical when they are re-united? The answer could help NASA make space travel safer for generations of astronauts to come.
