During astronauts' missions in space, in addition to scientific experiments, spacecraft construction and maintenance, space teaching is also an important part of their work. According to media reports, at more than 9 o'clock this morning, Jing Haipeng, Zhu Yangzhu and Gui Haichao, astronauts of Shenzhou 16, connected with the 23rd Summer Class Conference of International Space University held in San Jose dos Campos, Brazil, in the Mengtian module, and introduced the development process and achievements of China's Human spaceflight to the participants

During astronauts' missions in space, in addition to scientific experiments, spacecraft construction and maintenance, space teaching is also an important part of their work. According to media reports, at more than 9 o'clock this morning, Jing Haipeng, Zhu Yangzhu and Gui Haichao, astronauts of Shenzhou 16, connected with the 23rd Summer Class Conference of International Space University held in San Jose dos Campos, Brazil, in the Mengtian module, and introduced the development process and achievements of China's Human spaceflight to the participants. However, the connection only lasted for about 3 minutes, and it was suspected that it was interrupted due to leaving the relay measurement and control area.

Many people are very curious. When connecting to Sky Classroom for almost an hour, there is no problem. How can the signal interruption occur after connecting to Brazil Classroom for more than 3 minutes? After the Tianlian Relay Satellite, doesn't it mean that the three module configuration of the space station can already achieve seamless measurement and control?

In fact, although we now have two generations of eight space link relay satellites located in Geostationary transfer orbit and super synchronous transfer orbit, there is no space space over the Americas, which is the only blind area for measurement and control. The reason for the existence of this blind area has a great relationship with the United States. If there were a fixed point Skylink satellite over North America, it would truly achieve seamless relay.

In addition, having Skylink satellites in the sky alone is still not feasible, and we need ground observation and control stations to cooperate. The problem now is that we have too few observation and control stations in the Western Hemisphere, only one in Santiago. If we could also set up observation and control stations in Cuba, the situation would be much better. Of course, the best choice is to set up measurement and control stations in the United States.

We often say that the United States has hindered the common progress of humanity towards the sea of stars, which is a typical example. This time, it is clear that due to the United States not allowing us to set up measurement and control stations or sky link relay satellites on its own land, the students of the 23rd Summer Class of the International Space University missed an opportunity to communicate with our astronauts. This is a causal relationship, and it is precisely these small mistakes, The pace of exploring space in other countries will slow down, and even fail to start. As major powers continue to advance into deeper space, many countries and peoples are locked in the Earth as a result. The United States also wants to lock us up on the earth, so it would hesitate to form cliques in space. We are more willing to work with Brazil, Pakistan and other countries to find the path of common progress for all mankind.
