Cosmonauts on six-hour space walk
Cosmonauts based on the International Space Station are installing laser communication equipment and replacing experiments on the Zvesda module during a six-hour space walk.
Sergei Volkov has made two previous space walks, but this is the first for his colleague Alexander Samokutyaev.
The pair will also collect an antenna and release a small radio-transmitting satellite, a student-built experiment, while outside the station.
