Yesterday, the hatches between the International Space Station and Space Shuttle Atlantis were sealed for the final time and the combined crew were forced to say their goodbyes and separate into their respective chambers.

Hutcheson was preparing for the serving of beans and corn bread, a tradition that follows every successful launch.
