The three Expedition crew members aboard the International Space Station wrapped up the last full work week of 2007 with science experiments and unloading and stowing materials from a cargo craft that arrived early Wednesday.
The crew worked Friday on a number of biomedical experiments that focus on the long-term effects the station's microgravity environment on the human body. Flight Engineer Yuri Malenchenko began the day winding up overnight operations of SONOCARD, a Russian experiment which monitors crew physiological functions during sleep.
Later Malenchenko participated in study of the cardiovascular system under stress by working out on the VELO, one of two bicycle-like exercise devices aboard the station, while biomedical equipment collected data on his physical condition. Commander Peggy Whitson assisted Malenchenko.
Whitson and Flight Engineer Dan Tani each took turns working out with the CEVIS cycle ergometer while wearing a heart rate monitor to collect data for their own periodic fitness evaluations.
The crew continues to unload and stow supplies that arrived aboard the Progress 27 cargo craft on Wednesday. The Progress docked to the space station's Pirs docking compartment at 3:14 a.m. EST Wednesday after a launch at 2:12 a.m. Sunday from the Baikonur Cosmodrome in Kazakhstan.
The station crew members have received more than 6,000 greetings from Earth through a link on the nasa.gov home page.
