A satellite has suddenly disappeared! China's space scavengers worry the West
Near-Earth space, which is close to the Earth's surface, is not only one of the passages into space, but also one of the resources of near-Earth space. Many satellites and space stations operate in this area. Therefore, the near-Earth zone is of great importance for the development of the space industry.
For example, the concept of 6G technology is to combine Earth-orbiting communications satellites (NEOs) in space with ground base stations to achieve the unity of space and earth. This illustrates the importance of Earth-orbital resources, which can influence the development of not only space technology and the space industry, but also many other industries.
A lot of people have heard about Musk's SpaceX company and its Starlink program. The Starlink program is designed to bring 120,000 low-Earth orbit (NEO) communications satellites were put into orbit, a number that later increased to 420,000 pieces. On the face of it,"Starlink"The goal of the program is to provide global connectivity and develop 6G technology, but in reality, the massive launch of communications satellites into Earth orbit is also developing near-Earth resources.
Just imagine when"Starlink"How much the NEO will be after the launch of the planned 42,000 communications satellites"Busy", how difficult it will be to continue the launch of communication satellites on near-Earth objects.
The Starlink program has already sent 5 694 satellites, which is a very high number. On top of that, satellite launch opportunities will continue to increase as SpaceX continues to make technological breakthroughs in satellite launches.
SpaceX used to use the name"Falcon 9"low-tech rocket-launching satellites. However, SpaceX is now working on the Starship rocket, which can launch up to 400 satellites simultaneously.
However, we did not expect that one of our 2021 space debris removal technologies would attract the attention of the United States, Europe, and the United States. "praxis 21 "The satellite was an experimental satellite that we launched in September '21. Its main purpose and objective is to test space debris removal technology.
Some time ago, the Shijian-21 satellite successfully captured an obsolete Beidou satellite and put it into the target orbit within four days.
At that time, the U.S. commercial aerospace inspection company felt that it could not find this situation, only to find that the Beidou satellite suddenly disappeared from the orbit, so it had to take the initiative to pull into the target orbit, and after a series of finalities, it was found that these Beidou satellites practiced the ** of 21 satellites.
In this area of space technology, the United States is undoubtedly catching up with or even surpassing. Not only that, but the United States is also concerned about the impact of this technology on its own space assets.
Our space technology development is indeed in"Accelerate"Over the past few years, we have been receiving good news about breakthroughs in space technology. For example, we have made breakthroughs in relaunchable rocket technology and deployable satellites, and we have developed a global satellite constellation plan to launch tens of thousands of satellites.
Rapid development has also been made in the field of space stations and manned spaceflight. China's Shenzhou-16 rocket has set a record for sending non-professional astronauts into space for the first time in the history of astronautics"Moon Rabbit"The lunar probe successfully transported lunar soil. The Beidou satellite is also one of the world's leading navigation satellites with excellent performance.
Postscript. At present, our aerospace engineering has made rapid progress, with many technological breakthroughs and R&D results, and in some aerospace fields, it has even surpassed the world's leading countries. This is undoubtedly a testimony to the outstanding achievements of China's engineering and aerospace technology, and also a sign of the rapid development of China's science and technology.
