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.

Studies have revealed that crew members sleep significantly less during spaceflight compared to pre- and post-mission periods.
