Toxic smell detected on Space Station: Nasa reveals where it came from

Astronauts aboard the International Space Station encountered an unexpected situation when they detected an unusual odor after opening the hatch to the recently docked Progress 90 cargo spacecraft. As part of standard safety protocols, flight controllers on the ground swiftly activated air scrubbing equipment in response to the crew's report. The crew reported that the unusual smell dissipated rapidly, allowing cargo transfer operations to proceed on schedule without further interruption. NASA's advanced air revitalisation systems, which include carbon dioxide scrubbers and humidity control mechanisms, play a crucial role in ensuring astronaut safety and comfort during long-duration missions.
