Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev of Russia concluded their spacewalk outside the International Space Station at 4:23 p.m. EDT on Wednesday, May 27, 2026, lasting 6 hours, 5 minutes.

Kud-Sverchkov and Mikayev finished their major objectives, including collecting two completed science experiments and installing a new one. They removed a microorganism study from the exterior of the Poisk module and retrieved a cassette from the Nauka module containing data on how semiconductor materials form in microgravity. The crew also installed a device on the Zvezda service module to measure bursts of solar radiation from solar flares.

During the spacewalk, the duo photographed one of two Kurs rendezvous antennas on the Progress 94 cargo spacecraft that failed to deploy following its March launch to the space station. After collecting the imagery, they secured the antenna with a tie‑down for future dynamic operations.

This was the second spacewalk for Kud-Sverchkov and the first for Mikayev. It also was the 279th spacewalk supporting space station assembly, maintenance, and upgrades.
