(AP) -- Two Russian cosmonauts on Tuesday completed a nearly 7-hour-long spacewalk to replace a video camera and improve cable connections to the orbiting laboratory's newest module.
No significant difficulties were reported during the spacewalk by Fyodor Yurchikhin and Mikhail Kornienko, which was directed by Russian Mission Control just outside Moscow.
The cosmonauts replaced a camera used in monitoring docking of Automatic Transfer Vehicles, supply ships sent by the European Space Agency.
They also attached cables connecting the rest of the station to the Russian Rassvet module. Rassvet, used for storage and as a mini-laboratory, was delivered to the station in May.
