When it comes to foul odors that can't escape by simply opening a window, living inside a tiny metal box is not easy.
In a recent TikTok video, astronauts are on TikTok now, and one of them recalled the smell she encountered when she was in space.
"When I got here a couple of months ago for my second flight, I could smell a very peculiar odor that brought me back instantly to the memories and sensations of my first flight's odors," he said in the video.
When it comes to the International Space Station, Cristoforetti is a veteran. She spent 199 days in a row on the International Space Station, which is the longest continuous spaceflight by a European. She was sent to the station again in April, this time on a Crew Dragon spaceship.
A number of videos over her latest flight have been shared on TikTok.
The space station's stink didn't last long.
She said that the station's filters took care of most of the smell, and that she could no longer smell it.
That doesn't mean the outpost is free of odors.
The astronauts admitted in her video that there are places on the space station that can become a bit stinky.
If you're close to a lot of trash, the station recently sent a Cygnus spaceship full of crash to burn up in the atmosphere.
There are blue bags that hold the crew's toilet waste, which can be a little bit smelly.
The "brine" that is left after the water has been removed from the recycled urine can cause a stink on the station.
The space station smells good. It's reassuring.
The International Space Station has a peculiar smell.
There is more on the space station.
