Nowadays, International Space Station is performing a "thrilling" side, which is more serious than maliciously sabotaging the Soyuz MS-09 spacecraft in 2018.
At that time, the sudden air pressure drop of the International Space Station in was unimaginable in space, and the speed was quite obvious at that time.
Astronauts were also very anxious at that time, but fortunately they found the leak. It turned out that a through hole of with about 2 mm diameter was found in the orbital compartment of of the Soyuz spacecraft.
In an emergency, the commander of the Soyuz spacecraft flight crew, Prokopiev, directly blocked the leak point with epoxy resin, to avoid casualties.
You should know that leaking air in space is not a small matter, and it is undoubtedly a fatal blow to them. Balloon Everyone knows it. After it leaks, it flattened and then fell off.
Look back and see what happens if is about 400 kilometers away from the Earth's surface?
Assuming that the International Space Station suddenly falls out of control, will not only generate a large amount of space garbage, but will also cause great damage to the ground, and may even trigger a series of "wars".
It would be fine if there were no astronauts here. If there were astronauts, it would cause great harm to their lives.
But then again, what problems are the International Space Station facing this time? Could it be that someone maliciously destroyed it? Or is it another reason?
In fact, destruction is destruction, but the destructive power is not artificially created, but is caused by nature. What's going on?
Looking at this picture is quite beautiful, just like it snows. And it is the damaged Soochow MS-22 spacecraft. Some experts say that it caused the cooling system to leak due to the impact of meteorite .
Before this, many people were worried about whether astronauts would be harmed, but fortunately they did not affect them.
Due to the severe impact of the Soyuz spacecraft's shell, NASA and Russian State Space Corporation plan to use the Canadian arm 2 robot arm to conduct additional inspections on the Russian Soyuz spacecraft that had leaked.
After the inspection is completed, according to the Russian News Agency, the leakage of the Soyuz spacecraft may be caused by the micrometeorite , which will not affect the operation of the International Space Station, and may change only if the temperature of the instrument cabin is limited to the temperature.
I didn't expect that this is true. Due to the damage to the cooling system, caused the temperature of the Soyuz spacecraft to be at 50 degrees Celsius for 24 hours. If no measures are taken at this time, the Soyuz spacecraft's mission will be postponed.
So what should these astronauts do? Maybe they can only stay at the International Space Station unless there is another channel to "go home", and this is also very easy for them.
Let’s take a look first! What are the consequences of the continuous rise in the temperature of the Soyuz spacecraft?
will first cause the instruments and equipment in the Soyuz spacecraft to fail. Once the temperature rises to a certain level, it will take away people's lives. This is not impossible.
Do you still remember the Columbia Space Shuttle accident? It carried seven astronauts to space. Just as the mission was over and about to return, the friction between and the atmosphere caused a high temperature of about 2,000 degrees Celsius to enter the body.
so that the aircraft reached a critical point due to the continuous high temperature. In the end, the entire body of collapsed, and the seven astronauts instantly gasified, none of them survived.
What is going on? The reason for the accident was
The reason for the accident was foam insulation board , and was even more tragedy caused by the administrator's negligence. When
was launched, due to the continuous expansion of high temperature, caused the foam insulation plate to fall off and directly crashed into the strong carbon insulation plate of the left wing, and a small hole appeared on the left wing. and this small hole is also the reason why temperature enters the body.
This is exactly what we are telling us that whether in international space or on spacecraft, we must ensure that everything is foolproof. Only in this way can we protect the safety of astronauts. Once a vulnerability is found, it must be quickly remediated to avoid danger. Fortunately, when the Soyuz spacecraft was in an accident, the timely remedies of astronauts did not cause harm to the International Space Station.
But in terms of temperature, experts need to find a way to cool down. Only in this way can the lives of astronauts be protected. Some people also released news that experts are studying ways to reduce the cooling.
This is undoubtedly a great thing for them.
Let’s say that, aren’t there seven astronauts on the International Space Station?
So how should they go home? Needless to mention the Soyuz spacecraft, we all know that it is the one leaked from the cooling system. In fact, there is another spacecraft in China, that is, the Dragon spacecraft .
It can indeed carry seven astronauts home, but currently there are only four seats. means that the astronauts in the Soyuz spacecraft have to "go home" by themselves.
Moreover, this spacecraft is not a random seat. It is understood that the method used by the US and Russian astronauts to go to the International Space Station is to "swap seats". means that their respective spacecraft can carry an other astronaut.
Once the heat continues to be high, this matter will become very tricky. At this time, Russia needs to re-launch the Soyuz spacecraft for space rescue.
However, according to relevant information, it will take about a month for to launch the spacecraft even if it accelerates to rescue.
I was really shocked to see this. Did they have no backup at all? Or is their launch speed like this. This made me want to see how long it took for their spacecraft to fly to the International Space Station.
This really aroused my curiosity, let’s take a look! Currently, the Soyuz manned spacecraft uses two modes to travel to the International Space Station:
One is the fast flight mode, arrives in 6 hours, just go around the earth 4 times;
There is also another mode to fly around the earth for more than 30 times, which takes 2 days.
It didn’t take long to see this, so why does it take a month to go to the International Space Station for rescue?
It turns out that it has not been tested or related inspections in this, so it cannot go directly to space. It may take one or two months to go down.
and you still have to wait for the launch window. Of course, we don’t have to worry about these windows, there are still a lot of them.
Then, the question is here!
If it were the Shenzhou series of spacecraft in my country, how many days would it take?
As early as October 19, 2021, according to Global Network ,
Singapore’s Lianhe Zaobao said on the 18th that while China successfully launched the Shenzhou 13 manned spacecraft, the Shenzhou 14 spacecraft had entered emergency launch. "If Shenzhou 13 encounters an emergency, Shenzhou 14 can rush to space for rescue as soon as 8.5 days."
has to admit that this is China's speed!
And the way we have always taken is "Speed one, spare one". If they need it, we will also go to rescue. Although it is not that easy, we will use our greatest ability to help them.
It is worth mentioning that things are not as serious as we imagined. At the same time, I believe that they will definitely overcome this difficulty and lower the temperature.
