On September 9, the Russian Federal Space Agency Roscosmos said that the Zvezda service module – Russia’s main module on the International Space Station (ISS), had activated the smoke alarm system. Russian news agencies reported that astronauts on the ISS smelled burning plastic.

According to Roscosmos’ announcement, all systems have since returned to normal operation. The spacewalks on September 9 are still going as planned.

According to Roscosmos, the smoke alarm and alarm system was activated in the Zvezda module, the living quarters of the crew members on the ISS, when the battery system was in overnight charging mode.

Russian cosmonaut Oleg Novitsky saw smoke and smelled burning, while French cosmonaut Thomas Pesquet said the smell of plastic or Fire electronics spread from the Russian crew compartment to the American crew compartment.

In July, Roscosmos General Director Dmitry Rogozin said that there had been a prolonged depressurization in the Zvezda module. The depressurization occurred for two weeks before Russia launched the Nauka research module to the ISS. Nauka connected to the Zvezda service module on July 29.

Since last year, Roscosmos has detected an air leak in the Zvezda module. Although not a danger to astronauts, the leak continued despite efforts to patch the cracks on the ISS.

Zvezda – meaning “Star” in Russian, is the main Russian module on the ISS. The Zvezda has a cabin, life support and navigation systems, but no separate science room.

TTO – The Russian crew at the International Space Station (ISS) discovered new cracks that could spread on the Russian Zarya module. This is worrisome because cracks can spread over time.
