Cosmonauts' Spacewalk Uncovers ISS Coolant Leak Challenge

During a spacewalk, cosmonauts Oleg Kononenko and Nikolai Chub inspected and isolated a coolant leak from a radiator on the Nauka module of the International Space Station (ISS). While they initially couldn't find the leak, they later discovered traces where the radiator panels were connected. The cosmonauts attempted to clean up the coolant but ran out of towels, resulting in one end of a tether becoming soaked and potentially touching a cosmonaut's visor. The spacewalk also included the release of a nanosatellite and the installation of a synthetic radar communications system, although not all tasks were successful. Managers are still deciding on the next steps for repairing the leak.
