On Thursday, July 21, a Russian cosmonaut and an astronaut from the European Space Agency will perform a spacewalk to complete the installation of the European robotic arm in the International Space Station's Nauka laboratory. NASA will broadcast the spacewalk live.
On NASA Television, the NASA app, and the agency website, coverage will begin at 9:30 a.m. Eastern Daylight Time. The spacewalk is expected to begin around 10 am.
Roscosmos Commander Oleg Artemyev and Flight Engineer Samantha Cristoforetti from the European Space Agency will leave the Poisk module facing space to start the six and a half hour expedition, in the 67th Expedition Russian Orlan spacesuits.
Installing platforms and workstation adapter hardware close to the 37-foot-long manipulator system attached to the Nauka is the main goal of this project.
To facilitate future spacewalks, spacewalkers are also planned to move the arm's external control panel.
A protective window on the arm's camera unit will replace and extend a Strela telescopic boom from Zarya to Poisk.
The Canadian-made Canadarm2 robot arm and the Japanese arm are used in station maintenance, operations and research. The European robot arm will be used to transport cargo and equipment outside the Russian part of the station.
The 251st spacewalk, which will support station construction, maintenance and upgrades, will begin with Artemyev and Cristoforetti deploying 10 nano-satellites aimed at collecting radio electronics data.
Russian spacesuits with red and blue stripes will be worn by Artemyev and Cristoforetti, respectively. Cristoforetti, who will be the fourth European astronaut to spacewalk in a Russian spacesuit, will perform his first spacewalk, marking Artemyev's sixth spacewalk and the first for Cristoforetti.
