Russian module “Nauka” loses coolant

Date:

For the third time in a year, a leak has been discovered in a Russian module of the International Space Station (ISS). Coolant leaked from a spare cooler, but there is no danger to the ISS crew, it is said.

On Monday, around 7 p.m. CEST, the flight control team used cameras on the exterior of the ISS to detect “flakes” coming from the Russian research module “Nauka,” NASASpaceFlight.com founder and operator Chris Bergin said Tuesday. the platform X (formerly Twitter, see tweet below).

The crew aboard the space station was then notified of the possible leak, and NASA astronaut Jasmin Moghbeli confirmed that she could observe flakes from a window in a dome. The crew was then asked to close the window shutters of the American part of the ISS as a precaution.

No danger to the crew
According to the American space agency NASA, the crew aboard the ISS has never been in danger. Its counterpart, the Russian space agency Roscosmos, confirmed that the observed leak came from a spare radiator on the outside of “Nauka”. The module’s primary cooler is functioning normally and providing sufficient cooling to the module. The leak therefore has no impact on the crew or the operation of the space station.

As recently as December, coolant (pictured above) leaked from a Russian “Soyuz” capsule docked to the ISS. The leak may have been caused by the impact of a micrometeorite. In August 2020, an air leak occurred on the ISS. Sensors in the Russian “Zvezda” module had registered the leakage of air into space.
