ISS gains sun-watching telescope as Russians complete 6-hour EVA

Two Russian cosmonauts spent about six hours outside the ISS installing the Solntse-Teragerts sun-observing telescope on the Zvezda module, retrieving a semiconductor film sample from Nauka, inspecting a Kurs antenna, and completing multiple tasks. The telescope is designed to observe strong solar flares and run through 2028, while Kud-Sverchkov’s total spacewalk time rises to 12h11m and Mikaev records his first EVA; the outing also marked Energia’s 80th anniversary for Roscosmos.
