On Oct. 16, 2025, members of Expedition 73 and Russian cosmonauts Sergei Ryzhikov (station commander) and Aleksei Zubritsky of Roscosmos ventured onto the exterior of the Russian International Space Station (ISS) segment for more than six hours for the VKD-64 spacewalk. They installed the Ekran-M experiment for the production of semiconductors in the vacuum of space. The duo also removed a high-resolution camera monoblock, cleaned a window on the Zvezda service module, and removed a materials exposure experiment container.
