The two cosmonauts opened the hatch to the Pirs docking compartment to begin the spacewalk at 11:42 a.m. EDT. They re-entered the airlock and closed the hatch at 5:43 p.m.
During the spacewalk, the duo completed the planned tasks, including installing a handrail on the Russian segment of the complex, retrieving science experiments from the Poisk module’s hull; removing and jettisoning the plasma wave experiment hardware; and conducting maintenance work on the orbiting laboratory, such as cleaning the window of the Poisk hatch.
The spacewalk was the 217th in support of station assembly, maintenance and upgrades and the fourth outside the station this year.
This was the fifth spacewalk in Kononenko’s career and the first for Ovchinin, who will become station commander next month. Kononenko is scheduled to return to Earth June 24, with crewmates Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency, wrapping up a six-and-a-half-month mission living and working in space.
