Preface
In the 21st century, China has made remarkable achievements in the field of space technology, such as the establishment and in-orbit operation of China's space station, the launch and docking of China's manned spacecraft, and the global layout of China's Beidou.
Among them, China's Beidou technology, even the United States is not as good as the United States, just yesterday, the American Space News Network issued an article saying:
"China's Beidou satellite navigation system is making the U.S. Global Positioning System (GPS) lose its dominance. ”
The article lists China as America's most important competitor and urges the United States to regain leadership in positioning, navigation and timing over the next decade.
Many achievements in hand, coupled with the attention of the United States, so that many people have the illusion that China's aerospace has achieved "the world's first", although China is a space power, but there is still a distance from the real space power, especially compared with the United States.
How big is the difference between China and the United States in space technology? Has the mainland really caught up with the United States?
China Aerospace
Although China's aerospace industry started relatively late, after decades of development, it has also made a number of remarkable achievements, such as the "Shenzhou" Wentian, the "Beidou" guiding the way, and the "Chang'e" lunar exploration, each of which represents a new breakthrough in the field of aerospace technology.
In terms of launching artificial satellites, the mainland lagged behind the United States and the Soviet Union, and only launched the first artificial satellite in the 70s of the last century, but with the mainland's technological research, in the 90s, China's Beidou was officially launched.
After more than 20 years of development, China's Beidou has now achieved a global layout, which can provide all-weather positioning and navigation services for more than 160 countries and regions around the world.
China's Beidou has become the third most mature satellite navigation system after the United States GPS and Russia's GLONASS, plus the European Union's Galileo, forming the world's four major "satellite navigation systems".
It can be said that in terms of satellite navigation, the original GPS, which is the only one, has regarded China Beidou as the biggest competitor in the future commercial field.
In 2003, Shenzhou 5 was launched, and Yang Liwei was sent to space by China, opening the journey of manned spaceflight on the mainland.
After 20 years of research breakthroughs, our manned spacecraft has been launched to Shenzhou 17, and Shenzhou 18 is expected to be launched this month, and the technology of Shenzhou series manned spacecraft has been quite mature.
Not only can we fly around the earth, but we have also built a space station in space, and last year we realized the normal operation of the space station, and Chinese astronauts can work on it for half a year.
In space, in addition to China's space station, there is also an International Space Station, which is jointly built and operated by 15 countries and regions, including the United States, Russia, Japan, and the European Space Agency.
But China's space station completely belongs to China, that is to say, we in China have done what 15 countries can only do by ourselves.
In terms of lunar exploration, China has also been constantly innovating technology, and the Chang'e-5 probe launched by the mainland successfully obtained 1,731 grams of "lunar soil", which has a high research value, attracting the United States to apply for some samples.
In the exploration of Mars, the Tianwen-1 Mars probe launched by the mainland has revealed the superficial fine structure and physical characteristics of Mars, and the observation data of the Zhurong Mars rover shows that there is liquid water on Mars.
Over the past 20 years or so, China's aerospace development has been changing with each passing day, and it has constantly set new records for space exploration, but does this mean that China is "surpassing the United States" in the aerospace field? Is the gap between China and the United States really being equaled?
Comparison between China and the United States
In the past, in the field of aerospace, everyone had such a cognition: the United States, Russia, and Eurospace were in the first echelon, and China, Japan, South Korea, and India were the second echelon.
In the mid-to-late 20th century, the United States and the Soviet Union competed for hegemony around the world, and in the field of aviation, the two countries also competed at the same time, with the Soviet Union launching its first satellite in 1957 and the United States launching satellites in 1958.
At this time, China had just been founded for less than ten years, and its economic development was relatively backward, and the field of national defense was more important than aviation, so the mainland did not launch space exploration until the 70s.
In the beginning, we have lagged behind the United States for decades, so the fact that there is a gap between us is objective.
The United States achieved a manned landing on the moon in the 60s, and more than 60 years have passed since the American astronauts' phrase "one small step for me is a big leap for mankind."
But so far, no astronauts have landed on the moon, but it is expected that around 2030, the mainland may achieve it.
In addition, in terms of rocket research and development technology, the American "Raptor engine" is currently one of the most powerful liquid rocket engines in the world, and the American "Falcon" carrier rocket is the world's most powerful rocket with carrying capacity.
China's heavy-duty launch vehicle "Long March 5", as the strongest carrier rocket in Asia, is still far behind the "Falcon".
Although China has been catching up, growing into a space power, constantly narrowing the gap with the United States, and ranking among the first echelon in the world, we cannot say that it is a space power.
Chinese scientists have said that there is a distance of more than 10 years between China's aerospace and the United States' aerospace, and every Chinese astronaut should not be complacent, blindly arrogant, always maintain a sense of crisis, and continue to move forward.
China's future
In the face of the unknown space and the vast universe, China has worked hard to develop the aerospace industry and build a space power, in order to pursue our aerospace dream.
China started late and is still very young in this field, and we look forward to working together with other countries to pursue new technological breakthroughs in the field of aviation in an open, inclusive, and peaceful development attitude.
Earlier this month, China and Thailand signed a memorandum of cooperation to carry out space cooperation such as an international lunar research station, and last year, we also cooperated with Egypt, Pakistan and other countries to build satellite development infrastructure.
On the contrary, the United States still maintains a hegemonic Cold War mentality, regards countries that are becoming stronger as "enemies and adversaries", and openly targets and suppresses them in the international community.
It has always been the United States, not China, that has bullied the small and bullied the weak, and has always exercised hegemony in all fields, and China is willing to share the fruits of space development with other countries on an equal footing.
