Astronauts smell smoke, burning on Russia's ISS module
e incident, which the Russian space agency Roscosmos said happened at 01:55 GMT ahead of a scheduled spacewalk, is the latest in a string of problems to spur safety concerns over conditions on the Russian segment.
"A smoke detector was triggered in the Zvezda service module of the Russian segment of the International Space Station during automatic battery charging, and an alarm went off," Roscosmos said in a statement.
French astronaut Thomas Pesquet said "the smell of burning plastic or electronic equipment" wafted to the US segment of the station, Russian state news agency RIA Novosti reported, citing a NASA broadcast.
The Russian crew turned on a filter and after the air was cleaned up the astronauts went back to sleep, Roscosmos said.
"All systems are operating normally," Roscosmos said. ■
