According to the statistics of the World Toilet Organization, a person’s life is spent in the toilet for about 3 years. At this moment, perhaps you are reading this article on the toilet.
You may have complained that gravity is too small when you are constipated, but have you ever thought about an astronaut in a zero-gravity space?
Using the toilet in space has always troubled countless astronauts, because a little carelessness will cause the universe to “fly”.

In order to enhance the toilet experience of astronauts, NASA recently allocated a $23 million (about 150 million RMB) The space toilet was sent to the International Space Station.
There is no doubt that this is the most expensive toilet in history.
Where is the space toilet worth 150 million?
NASA’s new space toilet has been in development for 6 years and is called the Universal Waste Management System
Universal Waste Management System (UWMS)
In the zero-gravity space, the human large intestine is also in a state of weightlessness, no matter how hard it is, it cannot be excreted like the earth. It can only draw feces and urine out of the body through strong airflow. And stored in a special container, UWMS air flow is generated by a 3D printed titanium alloy dual fan separator.
The core components of UWMS
Compared with the old-fashioned space toilet, UWMS has also added a new feature, which is to automatically start the airflow when the toilet lid is opened, which can control the odor diffusion.
Don’t underestimate this function, because in space, you can’t naturally dissipate toilet odors by air flow like the earth, so those odors are frozen in the air. NASA astronaut Jason Hutt was very impressed with this odor:
“If you want to reproduce the smell, take a few dirty diapers,
