Cosmonauts Begin Spacewalk for Scientific Hardware Work

Roscosmos cosmonauts Sergey Ryzhikov (left) and Alexey Zubritsky (bottom right) work together to remove a high-resolution camera (HRC) monoblock during a six-hour and nine-minute spacewalk outside the International Space Station's Roscosmos segment. The HRC monoblock is part of a scientific optical telescope system designed to test compact radio-optical detectors for Earth observation, ecological monitoring, and emergency response.

Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev exited the International Space Station at 10:18 a.m. EDT, beginning a spacewalk to remove two completed science experiments from the Poisk and Nauka modules and to install a new solar radiation-measuring device on the Zvezda service module. 

Live coverage continues on NASA+Amazon Prime, and the agency’s YouTube channel. Learn how to watch NASA content through a variety of online platforms, including social media.  

The spacewalk is planned to last about five hours. Kud-Sverchkov is wearing an Orlan spacesuit with red stripes, and Mikaev is wearing a suit with blue stripes.
