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, The Associated Press reports.
They also attached cables connecting the Zvezda and Zarya modules to the new Rassvet module. Rassvet, used as a storage facility and a mini-laboratory, was delivered to the ISS in May.
It was Yurchikhin's fourth spacewalk and Kornienko's first, according to RIA Novosti.
Russian military repeatedly thwarted Turkey's attempts to deploy its troops to Syria, and stopped militants from moving further south
