Sorry! Sources said - "Soyuz" was beyond repair in orbit and it lost 44 liters of refrigerant.
This means that the International Space Station will either launch a new "ship" to "rotate" the space station astronauts, or it will not let them come back. This is completely impossible, right?
However, at this time, many people are thinking wildly - can China launch Shenzhou 16 to welcome the astronauts from the International Space Station home?
This is indeed a good idea. After all, China's Shenzhou 16 manned spacecraft is also "always ready". Is it feasible? Let’s take a look below.
"Soyuz" cannot be repaired in orbit
Since problems occurred with the "Soyuz MS-22" manned spacecraft of the International Space Station, both the United States and Russia and other relevant countries hope to solve this problem as soon as possible. This spacecraft is related to the issue of the "return to the ground" of the International Space Station astronauts.
Moreover, previously, due to problems with the spacecraft, astronauts’ extravehicular activities on the International Space Station were suspended. Therefore, the countries on the International Space Station are working hard to find a solution. However, whether this problem can be solved is indeed different every time. We can't figure it out either.
One moment, Russia announced that it wanted to solve the problem. The next moment, it said that it could not solve the problem and would launch the "Soyuz MS-23" manned spacecraft, etc.
No, according to a new report released by the Russian Satellite News Agency, insiders told the Satellite News Agency that it is impossible to repair the cooling system of the "Soyuz MS-22" manned spacecraft under space conditions. During the accident, 44 liters of refrigerant at 3 atmospheric pressure leaked from the spacecraft. This problem is difficult to solve.
Judging from the known situation, the pressure of the external temperature regulation system of the Soyuz MS-22 manned spacecraft dropped and the external cooling circuit was damaged. All the refrigerant leaked from the 0.8 mm hole in the radiator of the spacecraft instrument unit compartment in about 3 hours.
In this case it is impossible to inject 44 liters of refrigerant into the radiator at 3 atmospheres, not to mention that the temperature control system should then undergo special inspections under pressure, which is in principle impossible to do on track.
So, this is indeed bad news for the International Space Station. In the end, there is only one situation. If it cannot be repaired, the Soyuz MS-22 manned spacecraft can only be "abandoned" this time and then launch a new spacecraft.
However, the specific launch time has also become a question, and it is not known whether the Soyuz MS-23 manned spacecraft has been prepared in advance.
This is also a blow to the three astronauts who are returning. If it's not ready, that means the "on-orbit" time up there may be longer.
So, how to operate next is still a "question".
As for the cause this time, the Russian media also came up with a theory. Previously, the Russian Satellite News Agency said that it may be caused by the impact of the micrometeorite .
But Tass news agency reported a new report that the mysterious leaking hole in the Russian spacecraft may have been pre-made!
So, the reason is also controversial. However, judging from the current situation, no matter whether it can be repaired or not, we should be the first to find a way to solve the problem of astronauts returning to Earth. No, everyone has a lot of imagination.
The "Soyuz" cannot be repaired. Can China's Shenzhou 16 be launched to pick it up?
Indeed, there are two space stations in the world, one is the International Space Station, and the other is the Chinese Space Station . And it just so happens that the Chinese Space Station and the National Space Station are also different when they perform "spaceship missions".
When my country's Shenzhou spacecraft performs its mission, it adopts the "rolling spacecraft" launch mode. One spacecraft is launched, and with the exception of one spacecraft, it is in a "standby" state. Including the launch of my country's Shenzhou 15 manned spacecraft, it was also prepared in advance.
Therefore, Shenzhou 16 has always been on standby. Can China's Shenzhou 16 launch and pick up? This is actually the same as our previous discussion about whether the Chinese Space Station can directly dock with the International Space Station.
First of all, we will not discuss whether it is possible or not. "Legal" restrictions do not allow it.
As we all know, in 2011, the U.S. Congress issued an amendment called the " Wolf Clause ", which clearly stated that any joint scientific activities between the United States Space Agency (NASA) and the White House Office of Science and Technology Policy were prohibited, as well as technical exchanges with relevant Chinese departments.
And the International Space Station has the United States, so this article can directly "eliminate" the problem of help.
Secondly, the most important thing is that without this clause, China's Shenzhou 16 would not be able to launch, because this is preparation for our country's space station spacecraft.
Although we don’t want to see any problems with our country’s spacecraft, there is no way this will happen.
Therefore, we need to put our own safety "first", so we should not help in this regard unless our country's Shenzhou 17 is also ready and has extra spacecraft to assist.
There is another problem, that is, the structure of the International Space Station and the Chinese Space Station are completely different.
The International Space Station is a complex that mainly uses three docking devices: Probe-Cone (that is, pin-cone hole type), APAS-95 and CBM (common berthing mechanism).
In addition, there is a unique interface - a rod-cone docking interface, which can only be used by the Russian-made Alliance manned spacecraft and the Progress cargo spacecraft .
The components of the China Space Station are all domestically produced. Although the interface refers to the APAS-95 standard, it is different from the International Space Station.
Therefore, even if all the problems do not exist, China's Shenzhou 16 cannot launch and dock with the International Space Station. Only the Russian-made Alliance manned spacecraft can dock. This is "unchangeable".
Of course, many people may think about how the American "Dragon" cargo spacecraft successfully docked with the International Space Station. Since the spacecraft is docked with the International Space Station, it must also adopt docking construction standards, which are incomparable. The
interface must be the same as the reserved structure of the International Space Station, otherwise it would be impossible to connect. Therefore, the structure of the Chinese Space Station is different from the International Space Station, so it is impossible to assist. Don't think too much and use your imagination.
Summary
Overall, the problem of the International Space Station is still relatively serious. In addition to these leaks, the International Space Station has leaked many times for any reason. This also shows that the "retirement" of the International Space Station may occur early.
Although the United States has announced plans to destroy the International Space Station (ISS) in 2031, the wreckage will sink into the uninhabited area "Point Nemo" (Point Nemo) in the South Pacific.
However, countries with the International Space Station have been thinking of ways to extend the life of the International Space Station through various methods, but they have never reached a unified opinion.
Therefore, if the International Space Station continues to have problems, even the extended time may eventually change, and then there will really be only the Chinese Space Station.
