Their mission objective was to complete the connection of the Ethernet cabling to the new module, attach additional handrails to the module’s exterior, route cables, connect the TV systems and data lines and link-up the automated docking systems for future spacecraft missions. The cosmonauts also deployed two bio-risk containers as an experiment to gather data on better understanding the contaminants that could be a factor on interplanetary spacecraft.This was Russia’s 50th planned spacewalk and the third EVA in total for cosmonauts Novitskiy and Dubrov. The EVA was concluded at 2216 GMT, after seven hours and 25 minutes.
