Russian astronauts go on spacewalk to clean windows and upgrade station

Astronauts filmed five-and-a-half-hour walk on hand-held cameras and kept in touch constantly with each other and Russian mission control near Moscow

Two Russian cosmonauts added new equipment outside the International Space Station on Monday and took pictures to study its exterior during a five-and-a-half-hour spacewalk.

The outing was the 188th in support of the space station and the 10th of Gennady Padalka's career, a veteran cosmonaut and grandfather who is serving as commander of the space station.
