The cooling system on ISS is broken

The US Aeronautics Agency (NASA) has announced that one of the two cooling systems on the International Space Station (ISS) stops working, but the astronauts are still safe.

According to Reuters news agency, a NASA spokesperson said a cooling system on the ISS automatically stopped working after an abnormal temperature was detected. The problem may lie in a broken valve outside the ISS.

NASA said it is possible that astronauts will have to walk in space to fix this problem. 'But the astronauts working on ISS are not in danger and will not have to evacuate' - the NSA spokesman stressed.

Devices on the ISS affected by this incident have been turned off or switched to use a second cooling system, including three refrigerators that hold the test specimens to return to Earth.

NASA has stopped making space walks since July, after the Italian astronaut Luca Parmitano's leak of water leaks, causing him to drown more in space.
