Two cosmonauts conducted a spacewalk outside the International Space Station Thursday. Sergey Ryzhikov and Alexey Zubritsky spent a little more than six hours outside the station in a spacewalk that started at 1:10 pm EDT (1710 GMT). The two installed a semiconductor materials experiment on the exterior of the Nauka module and jettisoned a camera that had been mounted on the Zvezda module.
