Two Russian cosmonauts are back inside the International Space Station after conducting a spacewalk to install a semiconductor materials experiment, as well as retrieve and jettison a no-longer-needed camera from the exterior of the orbiting complex.
Expedition 73 commander Sergey Ryzhikov and flight engineer Alexey Zubritsky, both with Russia's federal space corporation Roscosmos, marked the end of their first extravehicular activity (EVA) together at 7:19 p.m. EDT (2319 GMT) on Thursday (Oct. 16). The two cosmonauts reentered the Poisk module's airlock and closed the hatch behind them, 6 hours and 9 minutes after they began the spacewalk at 1:10 p.m. EDT (1710 GMT).
