Russian And American Cosmonauts Walk Into Open Space

In the early hours of Tuesday the crew of Expedition 4 to the International Space Station (ISS) - Russian cosmonaut Yury Onufriyenko and American astronaut Carl Walz - walked into open space. According to the Russian Mission Control Centre, they will stay about six hours outside the station to fasten the second construction truss-crane to the Russian dock of the station to further speed up the unloading of Russian cargo ships docking at the ISS. The cosmonauts will also install a receiving aerial to establish connection with radio fans.
