ISS Expedition 10 Commander Leroy Chiao and Flight Engineer Salizhan S. Sharipov completed the second and final spacewalk of their mission 1 hour ahead of schedule, returning into the ISS after 4.5 hours. To help in navigation, Chiao and Sharipov installed a set of space-tospace antennas around a section of Zvezda, the Russian service module that would aid in the docking operations of Europe's Automated Transfer Vehicle (ATV) during a future cargo mission. The crew also attached a GPS unit to the Zvezda module to help the ATV. The ATV, scheduled to arrive during the next year, had the capability to deliver up to 8.5 tons (7,711 kilograms or 7.71 tonnes) of cargo, including 10,000 pounds (4,536 kilograms or 4.54 tonnes) of propellant. After the crew finished connecting the antennas, Sharipov returned to the Pirs docking compartment to retrieve a small satellite called NanoSputnik. The satellite, which weighed just 11 pounds (5 kilograms) and measured only 1 foot (0.31 meter) long, carried a transmitter designed to test control and orientation systems for small spacecraft during its 100-day mission. Sharipov released the satellite into a retrograde orbit by hand, while Chiao photographed the launch.
