MOSCOW, Jan. 22 (UPI) -- Two Russian cosmonauts successfully completed their work during the first space walk by the crew of the International Space Station in 2011, officials said.
Dmitry Kondratyev and Oleg Skripochka spent more than five hours in space and returned on board the ISS late Friday, RIA Novosti reported.
They installed a high-speed data device on the Russian service module "Zvezda," dismantled plasma-injector equipment and installed a television camera on a Russian segment of the orbiting space station.
They wore new Russian Orlan-MK spacesuits equipped with a digital computer during their space walk.
The ISS crew also includes Russian cosmonaut Alexander Kaleri, NASA astronauts Scott Kelly and Catherine Coleman, and European Space Agency astronaut Paolo Nespoli.
