Outside the International Space Station, Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner of the Expedition 72 crew conducted a spacewalk on Dec. 19 to install an experiment package designed to monitor celestial x-ray sources and new electrical connector patch panels, remove several experiments for disposal, and relocate a control panel for the European Robotic Arm that is attached to the Nauka multipurpose laboratory module. It was the 272nd spacewalk in support of station maintenance and upgrades, the second for Ovchinin and the first for Vagner.
