The International Space Station is a space station that orbits the Earth in orbit, mainly used for scientific experiments, and has high scientific research value, but we always ignore the living environment of astronauts on the International Space Station.
Is there gravity on the ISS, what is the astronaut meal like, and what is the scenery?
What is life like on the ISS?
A space station without gravity.
The International Space Station (ISS) is currently the largest artificial satellite in the world, orbiting the Earth in low orbit and orbiting the Earth at a speed of about 8 kilometers per hour.
The International Space Station (ISS) is a complex system of modules shared by many countries, including the United States, Russia, Canada, the European Union, Japan, and others.
The main task of the ISS is to conduct scientific research in the space environment and prepare for human exploration in deep space, and the ISS can conduct experiments not only in microgravity, but also in spacecraft life support technologies.
Because its orbit is not very far, it is possible to send people to the ISS by launch vehicle, conduct scientific experiments on the ISS, and then return people to the ground by launch vehicle after the experiment is over.
Of course, the living environment on the ISS is also different, because it is very close to the ground, so the space station will not bring too much time delay and time error to the astronauts, and at the same time, it will also be blocked by the atmosphere, so as to avoid the cosmic ray radiation caused by solar radiation, and also make the astronauts live on the ISS safer.
What is the difference between the life of an astronaut on the International Space Station and life on the ground?
Gravity is the most common thing on Earth, but there is no gravity on the International Space Station, so what kind of impact will the lack of gravity have on astronauts?
The International Space Station "stinks".
Astronauts live on the International Space Station without gravity, human living environment is on the earth, once astronauts arrive at the space station, they are faced with a life without gravity, no gravity will cause people's lives to become very difficult, the original simple thing may become very complicated.
There is no gravity on the ISS, but there is still enough gravity to pull the astronauts and equipment together, which means that if you put something on the ISS there, it won't float away, just like furniture on Earth.
But there is another problem without gravity, which is food, without gravity food can only float, and food will float into the astronaut's mouth, but because there is no gravity, the action of chewing will not be as convenient as on Earth, and only by chewing slowly can the food be chewed.
At the same time, without gravity, people's water will also change, because without gravity, it will cause water to float, so to drink water on the International Space Station, it is necessary to use straws to absorb water, and at the same time, it will also cause bathing to be wiped with wet wipes, and there is no way to wash it clean like on Earth.
Astronauts live alone on the ISS, even if there is no gravity, but the life of no one to take care of is especially difficult to eat, there are plants cultivated by astronauts on the ISS, but it is far from being able to meet the food needs of astronauts, so the ISS does not allow astronauts to stay on the space station for a long time.
In addition to the fact that the International Space Station has no gravity to make people's lives more difficult, there is also a particularly big reason, that is, the International Space Station is a closed environment, and many things are not easy to dissipate, so a lot of odors on the International Space Station are not easy to dissipate on the International Space Station, just like a closed ship, if there are more people on board, the air on the ship will become very smelly, and you will not be able to smell it, but when you enter the ship, you will smell the smell.
So when there is no one on the ISS, it emits some smells, and when people come to smell it, the smell will be very unpleasant, even "stinky".
But the smell on the ISS is not because it is dirty, but because the smell on the ISS is easy to condense on the air conditioning pipes, so when the new astronauts enter the ISS, open the door of the ISS, the air conditioner will stop working, and the air conditioner will stop working as soon as the air conditioner stops working, and the smell will be dispersed all at once, and the smell of the ISS will make people smell very unpleasant.
See the beauty of the earth through the sun.
Although life on the ISS is more difficult than life on Earth, there are many scenery that cannot be brought to us by cities on the ISS, that is, the scenery of the Earth can be seen from space on the ISS.
Astronauts on the International Space Station will have a wider field of vision, see more beautiful scenery, and also see the curvature of the entire earth, so they will better understand how precious the earth is.
Astronauts can also see the sunrise and sunset while observing the Earth on the ISS, as there are 16 sunsets and sunrises on the ISS, which allows astronauts to experience the beautiful scenery even when they are not watching a movie on the ISS.
Life as an astronaut on the International Space Station is hard, but it's also a joy because you can conduct scientific experiments on the space station in a way that no one else can experience.
epilogue
Life on the ISS is hard, but it is thanks to the completion of the ISS that people can learn more about the universe and prepare for subsequent deep space exploration.
