Commander Sunita Williams and ISS crew responded to a toxic smell from a cargo spacecraft.
A crew of astronauts aboard the International Space Station (ISS), led by Commander Sunita Williams, quickly responded to an emergency triggered after a strange “toxic” smell was detected when opening a cargo spacecraft.
The hatch of the Progress MS-29 cargo spacecraft, which had brought essential supplies like food and fuel to the ISS, was opened and an unusual odour was detected. Astronauts also found small droplets inside the spacecraft.
Detecting a potential hazard, the crew quickly sealed off the hatch and isolated the affected area from the rest of the space station.
What did astronauts do?
NASA acted swiftly and air-scrubbing systems across the station were initiated to purify the air. To ensure safety, crew members wore personal protective equipment (PPE) while monitoring air quality. The quick response helped the crew safeguard themselves and continue with their operations.
NASA has now confirmed that the air quality aboard the ISS had returned to normal and no safety risks remained for the crew. However, the cause of the smell remains unclear and investigations are on to determine whether the odour originated from the Progress spacecraft or from the vestibule connecting it to the ISS.
