Anonymous users2024-01-241. The cost of the Russian-made toilet system of the International Space Station is 19 million US dollars.
On July 3, 2007, the National Aeronautics and Space Administration (NASA) announced that it would spend $19 million to purchase a Russian-made toilet system for the U.S. module of the International Space Station. Previously, American astronauts on the International Space Station had to go to Russia to go to the toilet to go to the toilet. The cost of this toilet sounds a bit expensive, but all things considered, it's much cheaper than building your own.
Aside from the price, what else makes this toilet special? As you can see from the picture, the toilet is equipped with a legging fixing sleeve to help the astronaut fix the position. The system uses a complex process to collect excreta in one piece and then discharge it into a septic tank, and it uses three filtration steps to purify the liquid, allowing all sewage to enter and be converted into pure drinking water.
The advantage of the new toilet system is that it converts astronauts' urine into drinking water, instead of discharging urine into space, as was the case with the previous toilet system. It seems that NASA is also starting to learn to save money, but this toilet is really not cheap.
The new toilet facilities were officially delivered to the space station in 2008. Urinating in the state of weightlessness in space is a more troublesome and complicated matter. Especially in long-term orbital flights, environmental control and life support systems need to design a complex collection method that can deodorize, supply water, and be easy to disinfect.
Among them, the flush toilet is the most complicated, if the design is not good, the urine and urine will float out of the toilet due to microgravity, flying everywhere in the cockpit, just like "the goddess scatters flowers", it will become a disaster.
Astronauts going to the toilet is a "technical job". First, sit on a platform with your feet hanging down on two long steel pedals, and put your feet into the fixing sleeve on the pedals, similar to putting your feet into the stirrups when riding. Then hold the armrests on both sides of the toilet with both hands, and the most important thing is that the buttocks must be close to the edge of the toilet, so that the inside of the toilet is isolated from the outside, and the inside is completely sealed to form a "pumping toilet".
Urine is collected using a special funnel.
