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.

An unusual toxic smell was detected by the ISS crew after opening the Progress MS-29 cargo spacecraft. The astronauts found droplets inside and promptly sealed the hatch to isolate the potential hazard.

In a recent incident that triggered panic, astronauts aboard the International Space Station (ISS), commanded by Sunita Williams, took swift safety measures on November 23 after Russian cosmonauts reported an unusual toxic odor while opening the Progress MS-29 cargo spacecraft.

The space station's current crew includes Roscosmos' Aleksandr Gorbunov, Ivan Vagner and Alexey Ovchinin, and Nasa's Pettit, Nick Hague, as well as Sunita Williams and Butch Wilmore.
