#宇航员小便问题如何解决#
I know that.
Astronauts have gone through several stages of technological development to solve the problem of urinating in space, culminating in today's mature solutions. Here are the detailed methods and processes about astronaut pee problem solving:
Early Stages:
In the early days of astronaut space exploration, due to the limitations of technology, the solution to the problem of urination was mainly controlled by the willpower of astronauts. They may try to minimize eating before a space mission to reduce the urge to urinate.
However, in exceptional circumstances, such as waiting too long for launch, astronauts may not be able to control their urge to urinate, resulting in urinating in the suit. For example, former Soviet cosmonaut Yuri Gagarin and the first American cosmonaut Alain Shepard faced similar problems in 1961.
Using the collection bag:
As space exploration lengthens, astronauts need to live in space for a longer period of time, so simple willpower control is no longer sufficient. Thus, a special collection bag was invented. Such a bag is glued to the astronaut's buttocks and contains antimicrobial materials inside. Astronauts need to shake their hands and crush the bag after use.
The collection bag is brought back to the surface for special handling when the astronauts return to Earth.
Use diapers:
In the 80s of the last century, with the advancement of technology and material science, a space "diaper" was invented. This diaper uses a polymer absorber, which is able to absorb a large amount of urine, thus solving the problem of urinary urgency in astronauts.
Using a Space Toilet:
Currently, the main way astronauts solve the problem of urinating on a space station or spacecraft is by using a space toilet.
Urine is carried out through a "funnel" that is connected to a hose that connects the other end to the urine collection system. When astronauts urinate, they need to turn on the fan in the collection system and suck urine from the funnel through the hose into the urine collector.
Space toilets are designed with the gravity-free environment of space in mind, ensuring that urine doesn't drift around.
The solution to the astronaut urination problem developed from the initial willpower control to the use of collection bags, diapers, and finally the current space toilet system. The application of this system not only solves the physiological needs of astronauts, but also reflects the continuous progress of human space exploration technology.
