"Russian Space Station Leaks Raise Concerns about Program's Reliability"
The Russian Nauka module on the International Space Station has experienced a coolant leak from its backup radiator, posing no danger to the crew but prompting the closure of window shutters as a precaution against contamination. The primary radiator is still functioning, but the loss of redundancy is not ideal. This is not the first time the Nauka module has encountered issues, with previous incidents including unexpected thruster firing and leaks in other spacecraft. NASA has upcoming spacewalks scheduled, but it remains uncertain if they will proceed as planned.
