Cosmonauts Oleg Kononenko and Nikolai Chub went on a spacewalk on Thursday completing the deployment of one panel on a synthetic radar communications system on the Russian segment of the complex and installing equipment and experiments to analyze the level of corrosion on station surfaces and modules. This was the seventh spacewalk in Kononenko’s career, and the second for Chub. It is the 270th spacewalk for space station assembly, maintenance, and upgrades.
