Expedition 14 Commander Michael E. Lopez-Alegria and Flight Engineer Mikhail V. Tyurin undertook a spacewalk outside the ISS lasting 6 hours and 18 minutes. In undertaking his 10th spacewalk, Lopez-Alegria set another U.S. record, surpassing Jerry L. Ross’s nine spacewalks. Although Tyurin initially encountered problems with his spacesuit’s cooling system, causing his visor to fog up, he and Lopez-Alegria accomplished several tasks, including repairing an antenna. The antenna had failed to retract on 26 October 2006, when a Russian Progress vehicle docked at the ISS’s Zvezda service module. To ensure the antenna would not interfere with the undocking of the craft in April, Lopez-Alegria and Tyurin partially retracted the stuck antenna and secured it with wire ties, leaving 6 inches (15 centimeters) of clearance, a distance adequate for undocking. Lopez-Alegria and Tyurin also photographed a Russian satellite navigation antenna, changed out a Russian materials experiment, photographed a German robotics experiment, and inspected and photographed an antenna and the docking targets for the European cargo craft, the Automated Transfer Vehicle (ATV). The ATV, designed with greater capacity than the Russian Progress craft, had not yet made its first trip to the ISS.
