Two Russian cosmonauts spent nearly seven and a half hours outside the International Space Station on Thursday, performing station maintenance and tending to experiments. Alexander Skvortsov and Oleg Artemyev completed their 7-hour, 23-minute spacewalk at 5:33 pm EDT (2133 GMT), the first EVA for either cosmonaut. The two installed a communications antenna on the Zvezda module and moved a payload cargo boom on the same module. They also worked on several experiments mounted on the station's exterior, including those devoted to orbital debris monitoring and materials exposure. The EVA took about an hour longer than originally planned, but the cosmonauts did complete all the major tasks scheduled for the spacewalk.
