September 10, 2021

On Thursday, a smoke alarm went off in Russia’s segment of the International Space Station (ISS), and astronauts smelled “burning” on board, according to Russia’s space agency and NASA. The incident, which occurred at 01:55 GMT ahead of a planned spacewalk, is the latest in a series of issues that have raised safety concerns about conditions on the Russian segment.

“During automatic battery charging, a smoke detector in the Zvezda service module of the Russian segment of the International Space Station was triggered, and an alarm went off,” Roscosmos said in a statement. According to Russian state news agency RIA Novosti, citing a NASA broadcast, French astronaut Thomas Pesquet stated that “the smell of burning plastic or electronic equipment” wafted to the US segment of the station.

The Russian crew activated a filter, and after the air was cleaned up, the astronauts went back to sleep, according to Roscosmos. The space agency stated that a planned spacewalk would take place as planned.
