Recently, the domestic antenna has made a great contribution, the Signal transmitted back to the Earth by the Jupiter probe of the United States was captured by China's domestic deep space measurement and control antenna, after learning this news, the Pentagon immediately panicked, realizing that it is only a matter of time before it is surpassed, so how does the domestic antenna do this? What is the value of this move? It is understood that China currently has a huge deep space measurement and control network, can capture most of the signals in space, the capture of Juno signal of the deep space measurement and control antenna, even 7 years ago, from which it can also be seen that our prospects in the field of deep space measurement and control are immeasurable.

All along, deep space exploration technology is the focus of development in the field of space in the world, many countries in this aspect of the achievements, basically with the space exploration program synchronization, but to develop this technology is not easy, because the space signal of deep space exploration, often from the earth tens of billions of kilometers away from the star domain, which also means that these space signals are quite weak, must use a large-caliber deep space measurement and control antenna, in order to effectively capture these signals.

At present, there are very few countries that can develop large-caliber deep-space measurement and control antennas, before the world only the United States, Russia and ESA mastered this technology, such as Japan, India and other countries, although their domestic also built large-caliber deep-space measurement and control antennas, but the technology is from the United States, after detecting space signals, but also have to share data with NASA, in the case of limited experience, China's research in this regard has experienced a lot of twists and turns, Although our deep space exploration technology was developed in conjunction with space exploration, the progress of this technology was stagnant due to limited investment in space research in the 1980s and 1990s.

But fortunately, China's foundation is good, after a number of technical research, we have successfully carried out a large-step development in the field of deep space exploration technology, in just a few years, we have successfully developed a domestic large-caliber deep-space measurement and control antenna, China has thus become the fourth country in the world to independently develop large-caliber deep-space measurement and control antennas, after a breakthrough in equipment technology, then we began the global layout, in the past few years, successfully deployed large-caliber deep-space measurement and control antennas in Africa, Southeast Asia and other places, And successfully realized the cross-intercontinental deep space exploration.

In addition to Africa and Southeast Asia and other places, in 2015, China also successfully built a deep space measurement and control station in argentina, the backyard of the United States, which is also the first time we built a complete deep space measurement and control station in overseas areas, in addition, in the ocean, the scientific research team also relies on the long-range series of space ocean survey ships to supplement, so that China's deep space exploration network is almost all over the world, in this context, our deep space exploration network can not only cover about 90% of the area of Mars, but also detect space signals farther than Mars. This has been confirmed by the capture by China of the signal sent back by the Juno Jupiter probe in the United States.

In general, in the case of China's deep space exploration technology is becoming more and more mature, the future of the international deep space exploration field leader, from the United States to China is not impossible, although the current deep space exploration technology compared to the United States is still a certain lack, but I believe that in more capital investment, as well as the unremitting efforts of the scientific research team, this part of the gap will soon be filled, China's voice in the entire space field will become larger and larger.
