It's too dangerous! The International Space Station was almost hit again, and it has to be said that this space junk is too dangerous. Once it collides, it may encounter a "chain effect" and even threaten astronauts in space. What is the matter?

In fact, this situation is not surprising, as the Chinese space station has also encountered the same situation.

So, during the mission of China's Shenzhou 17 manned spacecraft, repairs must be carried out, as China has also encountered the threat of space debris. Let's first take a look at the International Space Station and then take a look at the problems with China's space station.

Almost got hit! Emergency Orbit Change of the International Space Station

According to foreign space networks, the International Space Station underwent an emergency orbit change several hours before the arrival of a cargo spacecraft due to the threat of space debris.

The Russian Space Agency has already announced the incident, but the US Space Agency (NASA) has not provided a specific explanation yet, stating that confirmation of the incident is still needed.

According to the Russian Space Agency, when encountering space debris or debris, the International Space Station has been lifted by hundreds of meters. However, in comparison, the average orbital range of the International Space Station is still around 400 kilometers.

So, if it were not discovered this time, the International Space Station may have caused an impact in space. This time, it was also in an emergency situation and an orbit change was taken, but fortunately it was avoided.

Of course, the International Space Station has also been physically impacted. In 2021, the Canadaarm2 robotic arm of the International Space Station was hit by space debris, and the published images can also be seen. Therefore, it is not the first time that the International Space Station has faced the threat of space debris, and there have also been practical impact events.

According to a report released in 2022, a total of 37 orbital changes were made to the International Space Station due to the threat of space debris or debris, and in August 2023, two orbital changes were also made, which can be said to be quite frequent. Moreover, in addition to the larger spacecraft taking evasive measures, even very small satellites do so.

In June 2023, SpaceX submitted a report to the Federal Communications Commission (FCC) stating that its Starlink broadband satellite conducted over 25000 evasive maneuvers between December 1, 2022 and May 31, 2023. So, the threat of space debris is already a global issue.

According to human tracking of space debris data, there are approximately 34600 space debris, and there may be 130 million fragments in orbit that cannot be accurately detected or tracked due to their small size.

However, this is not the only point. With the continuous launch of space vehicles by humans, more and more space debris is also emerging.

So, if we don't clean up space debris in the future, sooner or later the space threat that humanity will face will become even greater. More and more spacecraft will be hit, and there may even be a chain effect under strong impacts.

Not only the International Space Station, but also the Chinese Space Station has encountered

That's right, the International Space Station has encountered the threat of space debris, and the Chinese Space Station has also encountered it. This is a practical announcement.

During the launch of the Shenzhou 17 manned spacecraft, China publicly stated that due to the increasing number of space debris, it is inevitable that long-term operating spacecraft will be impacted by small particles in space.

Preliminary inspections have found that the space station's solar wing has also been repeatedly impacted by small particles in space, causing minor damage. So, this is not only a problem for the International Space Station, but also for the Chinese space station.

However, the solar wing of the Chinese space station was hit and fortunately did not have any significant impact.

After multiple impacts, the various functions and performance indicators of the Chinese space station have met the requirements. However, considering the long-term operation and verification of technical capabilities for the space station, the Shenzhou 17 astronaut crew will conduct experimental maintenance outside the spacecraft through extravehicular activities, which is a highly challenging task and will elevate the ability and level of extravehicular activities to a new level.

Therefore, this mission will be a brand new mission challenge for astronauts Tang Hongbo, Tang Shengjie, and Jiang Xinlin of Shenzhou 17, which is an undeniable fact. Moreover, it is the first time China has conducted such a mission, and for astronauts, this pressure may also be considerable.

Of course, looking back, I personally am quite certain about the strength of China's aerospace industry, as it pursues excellence, stable development, and so on. Therefore, it is inevitable that the task can also be completed perfectly, which is the general situation.

Can't humans handle it anymore?

Indeed, globally, humans do not seem to have a good way to clean up space debris, otherwise such a situation would not have occurred.

In theory, there are many effective ways to deal with space debris, mainly by minimizing its quantity - specific solutions include reducing the launch of objects unrelated to flight missions, extending the service life of satellites as much as possible, strengthening the research and development of recoverable satellites, enhancing the quality of aircraft, and preventing in orbit disintegration.

At the same time, some space debris can be recycled and reused. For example, towing some usable nuts, bolts, and electronic equipment components out of Earth orbit using a tugboat spacecraft.

Disassemble or reassemble it for reuse, use equipment such as nets, harpoons, and robotic arms to grab space debris, recycle and clean it, carefully inspect some satellites, and then repair and update them to rejuvenate and continue to function.

These are some of the processing methods.

Obviously, these methods may not be the best way to handle large-scale space debris, so strictly speaking, there is no good way to handle space debris.

Moreover, over time, space debris will continue to increase, which is a trend. In the process of spacecraft launch in the future, humans may encounter such a situation, which is to shuttle directly through space debris.

Moreover, if you have any impression, when India launched the Lunar New Year spacecraft, it was delayed by 4 seconds to avoid the impact of space debris. This is the first disclosure made by India at the International Space Congress.

This also indicates that space debris is an important influencing factor for future human space exploration, and it is unknown whether there can be a very good way to clean up space debris in the future. If this continues, even ground-based astronomical exploration and other tasks may undergo a complete transformation. Too much debris will interfere with its normal exploration rhythm, which is the general situation.
