Summary

This video is a live broadcast by NASA of Roscosmos spacewalk 66, conducted by cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev outside the International Space Station. The spacewalk, lasting about 5.5 hours, involved installing a solar radiation experiment on the Zvezda module, removing science hardware from the Russian segment, and inspecting a failed antenna on the Progress 94 spacecraft. The broadcast includes real-time commentary from NASA mission control, translations of conversations between the cosmonauts and Russian flight controllers, and detailed explanations of the procedures. The video captures the entire spacewalk from pre-breathing and depressurization to hatch opening and the various tasks, providing an educational look at the complexities of extravehicular activities. It also highlights the collaboration between NASA and Roscosmos and the technical aspects of spacesuit operations and robotic arm use.
