The six-member Expedition 27 crew is back to work after docking activities on Wednesday and an off-duty day Thursday. They reviewed roles, responsibilities and emergency procedures and conducted the usual complement of science and maintenance activities. New flight engineers Alexander Samokutyaev and Andrey Borisenko were busy inside the Russian segment of the International Space Station. Samokutyaev worked on a science experiment that measures radiation inside the orbital laboratory. Borisenko unloaded cargo from the newly docked Soyuz TMA-21 spacecraft. Flight Engineer Ron Garan, who also joined Expedition 27 on Wednesday night, worked in the American side of the space station. Garan checked out the Water Processing Assembly in the Destiny laboratory and worked on cooling loops in the Columbus laboratory.
