Recently, someone took a picture of the starlink crossing the night sky and uploaded it to the Internet, which once again pushed Musk's starlink plan to the cusp of mass discussion, in fact, with the successful launch of a batch of satellites, Musk and the SpaceX company behind him have gradually exposed their ambitions, these satellites will not only occupy a lot of orbital space resources, but also let him alone own half of the world's satellites in orbit, which will be a great impact on the existing space development rules. So the European space director even personally warned that the rules of space will be changed under the influence of the Starlink program, and he also called for common principles, as early as January 2015, Musk announced that Space X plans to launch 12,000 communication satellites into orbit, of which 1584 will be deployed in low-Earth orbit at a height of 550 kilometers, and work will begin in 2020.
On February 22, 2018, Vandenberg Air Force Base in California successfully launched a Space X Falcon 9 rocket to put two small experimental communication satellites into orbit, which marked the official launch of the Starlink program, and if all goes well, the system will provide low-cost Internet services to users around the world.

The United States and Musk himself obviously have high expectations for this plan, and the international community is not very optimistic about the series of satellites launched by Space X in order to provide network services to global customers, this is because these satellites have a series of shortcomings compared with 5G ground base stations, StarLink can indeed provide users on the mountain with up to 250G bandwidth services, and in shopping malls, buildings, stations and office buildings, a large number of users are blocked by layers of walls, it is difficult to receive network signals from satellites Secondly, the power of the smart phone is completely insufficient to meet the needs of communication with the satellite, even the low Earth orbit is 550 kilometers from the ground, if the ordinary smart phone wants to communicate with the communication satellite, it needs to have a very strong transmission power, and a smart phone obviously does not have such performance, even if the company prepares a circular receiver with a diameter of half a meter for the user, for enhancing the signal, There are also few users who are willing to carry such a big burden in their daily lives.
If this program does not seem suitable for civilian applications, why does Musk pursue it so vigorously that the European Space Agency has warned about it? This brings us to musk and the ambitions of the United States and even the US military behind it, as the largest satellite launch program in human history, whether it is the total number of satellites after launch or real-time coverage, it has refreshed all the records in human history, as long as these satellites are available, the United States can use them to monitor and command any global war zone in real time, so that it has communication capabilities that are difficult to be interfered with and cut off, even if the enemy uses anti-satellite weapons. It is also almost impossible to destroy tens of thousands of satellites in a short period of time.

In addition to the military threat, the international astronomical community has also expressed concern about this, according to the recent news released by space X, the Starlink program will continue to launch more than 30,000 satellites in the future, these satellites that continue to shuttle in space will not only increase the probability of "space traffic accidents", but also cause astronomers to make it difficult for astronomers to observe the universe, especially the ubiquitous electromagnetic waves emitted by these satellites, which will use radio waves for radio telescopes and the like. The indelible impact of the means of observing the universe, not to mention that these satellites will occupy a large amount of orbital resources, which is the main reason why the Director of the European Space Agency has warned that space rules should be reformulated.
