Russian cosmonauts aboard the ISS were forced to seal a hatch and don protective equipment after the arrival of a cargo vessel brought with it a bizarre smell.

A Russian segment of the International Space Station was locked down this weekend after cosmonauts found an “unusual odor” emanating from a visiting cargo capsule, NASA said.

The hatch between a Russian cargo ship and the International Space Station (ISS) is finally open after a foul stench initially prompted astronauts to seal it off. The good news is, the smell has not lingered and NASA may have figured out the cause.

A strange smell stalled space operations on the International Space Station this week. NASA had to delay unloading a Russian spacecraft cargo delivery because of the concerning odor. The good news is that all the astronauts were safe during the ordeal and can enjoy a special Thanksgiving feast in orbit.

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.

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.
