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 sent a US$23 million (about 150 million) space toilet 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. The full name is Universal Waste Management System (UWMS). It weighs 45 kg and is 71 cm high. The size of the toilet used by the former space station is reduced by 65% and weight by 40%, which can be integrated into the life support of different spacecraft.
