Russian cosmonauts encountered leaking coolant during a spacewalk outside the International Space Station Wednesday. Oleg Kononenko and Nikolai Chub inspected a radiator on the exterior of the Nauka module that suffered a coolant leak earlier this month. They reset valves to isolate the coolant, and in the the process noticed a large blob of coolant on the exterior of the module, prompting flight controllers to tell the cosmonauts to keep their distance from it to avoid contamination. The cosmonauts also installed a radar antenna on Nauka, but one of its panels failed to deploy, and released a student-built smallsat intended to test a solar sail. The sail did not deploy.
