NASA astronaut Matthew Dominick (center) poses for a portrait with Expedition 71 Commander Oleg Kononenko (left) and Flight Engineer Nikolai Chub (right), both Roscosmos cosmonauts. Dominick was inside the Poisk module assisting Kononenko and Chub as they prepared their Orlan spacesuits for a spacewalk. Kononenko and Chub will exit the orbital outpost’s Poisk airlock at 10:55 a.m. EDT on Thursday for a planned seven-hour spacewalk. The cosmonaut duo will work outside in the vacuum of space to install hardware and science experiments on the station’s Roscosmos segment. #roscosmos #cosmonaut #nasa #astronaut #spacewalk #walk #poisk #international #space #station
