The 3 astronauts of Shenzhou 13 successfully returned!
Our astronauts have arrived home safely and have eaten strawberry-flavored tomatoes, and the Shenzhou XIII mission was a complete success. Next, we will launch Shenzhou 14 and Shenzhou 15 manned spacecraft, of which Shenzhou 14 and Shenzhou 15 manned spacecraft will be in orbit to take over, and 6 astronauts will spend about 1 week together on the mainland space station.
However, on the other hand, the International Space Station reached a maximum of 13 people, so is the continental space station inferior to people, why can it only accommodate 6 people at most?
Continental space station
The first thing to say is that the continental space station is indeed not as large as the International Space Station, the International Space Station is about 423 tons, and the continental space station will eventually be built into a 180-ton space station.
The "big" of the International Space Station is because it is a super project jointly built by many countries, led by the United States and Russia, and the space station has been docked by multiple modules.
The "smallness" of the continental space station is not because we are backward, but is designed according to the national conditions of the mainland.
In terms of scale, we are indeed inferior to the International Space Station, Yang Hong, chief designer of the responsibility of the Tianhe core module, said:
We do not compare the scale and efficiency with the International Space Station, and the purpose of our development of the space station is to support large-scale scientific experiments and technological experiments in space.
Although the weight is not as good as the International Space Station, the weight of the equipment used in scientific experiments is very obvious compared to the proportion of the weight of the entire station.
Secondly, the International Space Station is very chaotic, and it can be seen from the exposed pictures that the International Space Station has many exposed wires, and the placement of many equipment is also messy.
The messy results are bound to lead to the loss of things, and it is true that the International Space Station was once revealed to have more than 200 things that could not be found. He was also forced to abandon the spacewalk because of the loss of a chemical filter cartridge.
The messy International Space Station still hides dirt and dirt, and many garbage that should be thrown away have not been discarded, which seriously affects the work efficiency and life experience of astronauts, and has been forced to do a big cleaning and throw away a lot of garbage.
The continental space station does not exist in this problem, from the exposure of the picture during this time, it can be seen that the continental space station is neat and orderly, there is no bare wire at all, and the overall appearance is a Huawei store, which is very scientific and technological.
The reason for this is actually because the mainland has considered the placement of things at the beginning of the design, and has arranged switches where electricity is needed, so as to avoid bare wires.
In addition, the mainland has also established a material management system, each thing has a two-dimensional code on it, after scanning with the corresponding instrument, it will know where it should be placed, as well as the specific dosage, which is very convenient and clear to help astronauts understand the current situation of the continental space station.
This is actually a modular management method, even if there are new needs in the future, it can also be designed and arranged according to this specification, so that the future continental space station will not appear as messy as the International Space Station.
In addition, the continental space station is also equipped with many of the latest technologies, such as: equipped with a Hall engine; large flexible solar cell wings, power conversion rate of more than 30%; and regeneration bio-protection technology, which can recycle astronauts' sweat, space station water vapor and urine, etc., and be used for oxygen production or drinking.
Although the continental space station is small, the available space is large and the utilization rate is high, which means that although the continental space station is small, it has many functions.
The International Space Station can have up to 13 people, why is there only 6 people on the mainland?
At its peak, the International Space Station accommodates 13 astronauts, while the Continental Space Station can only accommodate up to 6 people.
In fact, although the International Space Station accommodates a large number of people, there are not enough beds.
According to "Our Space", in April 2021, the International Space Station only has 7 permanent compartments, which means that only 7 astronauts can have beds, so how should so many astronauts sleep?
The answer is to lay the floor.
In fact, the ground paving has become a routine operation of the International Space Station, and whenever the astronauts of the International Space Station are handed over, there will always be a scene where astronauts need to lay the ground.
Fortunately, there is no sense of direction on the International Space Station, whether it is vertical, upside down, horizontal or upright, the same for astronauts, as long as you find a place with good ventilation conditions, the noise is not too large, and do not delay the work of others, you can lay the floor.
At one point, Japanese astronaut Akihiko Hoshide slept in the astronaut sports barn, American astronaut Shannon Walker slept in columbus, and Victor Glover would sleep in the airlock cabin.
The continental space station is different, in order to let the astronauts can sleep well, the continental space station specially arranged an independent rest space for each astronaut, and in order to let the astronauts rest well, we also used a separate bed parallel to the ceiling of the space station, the beds have portholes, you can look at the earth through the portholes, and look at the universe.
Many of the international space station rest areas do not have portholes, and the location is not as reasonable as the mainland sleeping area, but there are sleeping areas up and down the left and right, and the sense of space is somewhat confused.
Nowadays, there are 3 beds and 1 bathroom in the continental sky and core module, and in the experimental module of the follow-up launch, there will be 3 beds and 1 bathroom, so as to ensure that 6 astronauts have their own separate rooms, and the toilet will not be crowded.
In fact, every inch of space on the space station is precious, but even so, in order for the astronauts to get a better rest, we would rather leave them a private space.
