When astronauts on the ISS opened the hatch of the Russian space shuttle Progress 90 this weekend, they were greeted by a terrible stench. The odor was described as “poisonous” and the hatch was immediately closed. Now everything is clear, but the origin of the source of the smell remains a mystery.
The unmanned space shuttle has docked at the International Space Station to provide three tons of fuel, food and supplies. But in addition to the unpleasant odor, the Russian crew members also noticed small droplets when they opened the hatch of the space freighter. The incident was shared by the official ISS account on X.
The hatch was then immediately closed and the space station’s air purification systems were turned on. But the pollutant sensors could not detect hazardous substances in the air on board.
Source of odor unclear
Russia’s Space Web platform described the smell as toxic – the cosmonauts even donned protective gear out of concern. An additional air purification system was activated for half an hour in the Russian section of the station. The source of the odor could not be determined. Sunday evening was the day
In December 2022, there was already a problem with a Russian spacecraft: a leak was discovered in the cooling system of a Soyuz space shuttle. In early February, a Progress space freighter suffered a leak. There is also a leak in the Russian part of the ISS, which NASA describes as ‘a major safety risk’.
