On Oct. 28, 2025, members of Expedition 73, Russian cosmonauts Sergei Ryzhikov and Aleksei Zubritsky worked on the exterior of the Russian International Space Station (ISS) Segment, after having successfully completed a spacewalk 12 days earlier. The main task of the VKD-65 spacewalk was the installation of hardware for the second phase of the Impuls experiment on the exterior of the Nauka module. The experiment developed at Moscow Aviation Institute, MAI, consisted of two units—the Pulse Plasma Injector, IPI-500, to be mounted on the pre-installed adapter and the component for the Control of Vacuum and Electro-Physical Parameters, KV EFP, to be installed on the opposite side of Nauka, not far from its main window. The VKD-65 spacewalk was 277th in the history of IIS.
