On May 27, Russian cosmonauts Sergey Kud-Sverchkov (commander of Expedition 74) and Sergei Mikaev conducted a successful spacewalk lasting 6 hours and 5 minutes outside the International Space Station (ISS). During this extravehicular activity (EVA), they installed the Solntse-Teragerts telescope on the Zvezda service module, which is designed to observe solar flares and enhance scientific understanding of solar activity. The telescope is expected to operate until 2028. The cosmonauts also faced challenges while retrieving a cassette containing semiconducting material from the Nauka module, including losing tools and communication issues. Despite these difficulties, they managed to collect the sample. The EVA was also a moment of celebration, as they recognized the 80th anniversary of RKK Energia, Roscosmos' design bureau. This spacewalk was significant as it was the first for Mikaev and added to Kud-Sverchkov's total of 12 hours and 11 minutes in space. Overall, all planned activities were successfully completed, marking another milestone in ISS operations.
