BEIJING, Oct. 23 (Xinhua) – In the 1980s, when German scientists conducted microgravity experiments on recoverable Chinese satellite, Chinese space engineer Tang Bochang was busy solving technical problems, while keeping carefully Chinese secrets. Tang joined the Chinese Academy of Space Technology in 1970, the same year that China launched its first satellite. He participated in the development of satellites recorded from the first successful launch of China in 1975.
Soon after, China began to open its space missions to the outside world as a result of its reform and opening up.
"At that time, only the United States, the Soviet Union, and China had mastered the technology of recorded satellites, and the International Space Station had still not been built. Germany have therefore asked France and Germany to use China's recoverable satellite to carry out experiments "
" They were curious about Chinese space technology, but they told us have also kept their secrets, "he said.
In delicate circumstances, China and the Western countries began their collaboration. Despite their respective concerns, the cooperation gave each party more opportunities for space exploration.
COOPERATION BETWEEN TIME AND SPACE
In the early 1980s, China sought to develop transmission-based remote-sensing satellites to obtain real-time satellite imagery. 19659002] At that time, China was still relatively late and was hoping to collaborate with other countries to develop such types of satellites. But the United States and Europe, who mastered the technology, were hesitant.
Finally, China found a partner: Brazil, also a developing country. In 1988, the two countries signed an agreement to jointly develop the Sino-Brazilian land resource satellite.
They shared the costs and developed their systems separately. Both parties had advantages and were very complementary.
Ma Shijun, former project manager, recalled that the main obstacle to cooperation was language. Engineers often had to handle dictionaries in hand.
The distance between the two countries also made the task difficult.
"But the technicians understood and used their advantages to the full, we learned about the international practice of satellite development and the technicians broadened their perspectives," said Ma.
"The two parties examined the documents and reports, which was a double check, thereby reducing the risk of error. "
In 1999, the first China-Brazil land-based resource successful launch of the satellite, giving each country their first transmission-type remote sensing satellite. It has been ranked among the 10 biggest scientific and technological advances of the year in China.
This was the first satellite developed jointly by China and another country, and provided a good example of cooperation among developing countries in space technology. and was hailed as a model of "South-South cooperation".
The cooperation lasted 30 years. Both countries sent four satellites in space. The resolution of the images has progressively improved.
Satellite data on land resources between China and Brazil are provided free of charge to developing countries. Satellites have also helped monitor disasters such as forest fires in Australia, floods in Pakistan, and an earthquake and tsunami in Japan.
S 'ASSOCIATION WITH SPACE PROBE
In 2005, the two Chinese space science satellites joined the satellites of the European Space Agency will complete the first global joint and synchronous exploration in six points of land space and will get important data.
This is the first scientific satellite cooperation between China and Europe. Along with renowned space projects such as the Hubble Space Telescope and the Mars Rovers Spirit and Opportunity, this project has been awarded by the International Academy of Astronautics.
With its growing economic and technological power, China has become an important and leading player in space, encouraging more countries to participate in its space programs. Scientists from China and other countries are working together to probe the universe.
One of the detectors of the Chinese explorer of dark matter particles, launched in 2015, was jointly developed by scientists from China, Switzerland and Italy. The Chinese space laboratory Tiangong-2, launched in 2016, is equipped with a gamma polarization detector developed by scientists from China, Switzerland and Poland. China and Italy have developed a satellite to observe electromagnetic earthquake information
. A satellite developed by China and France will soon be sent to space to study ocean winds, waves and climate change. Both countries are also working on an astronomical satellite.
A Sino-European joint mission, the Explorer of Solar Wind Ionosphere and Magnetosphere Links (SMILE), will be launched in 2021.
Improved X-ray Synchronization and Polarimetry ( eXTP) to explore still mysterious celestial bodies, such as black holes and neutron stars, that China plans to launch, by 2025, has attracted scientists from more than 20 countries, including the United States. Italy, Germany, Britain and France.
The Chinese Chang & # 39; The lunar probe e-4, which is due to be launched in December this year and is expected to become the first probe to land on the other side of the moon, carries German and Swedish detectors.
China welcomes other space agencies to participate in its lunar exploration programs and jointly build a research station on the moon.
Yu Dengyun, deputy chief designer of China's lunar exploration program, said that international cooperation had become commonplace in space exploration. The costs, challenges and risks of any space project are enormous.
"If we can share global wisdom and share the risks and costs, we can achieve the goal of space exploration faster, which benefits everyone," he said. Mr. Yu. [19659002] LEARNING TO COEXISTER
China announced in May that it would like all UN member states to cooperate and jointly use its future space station, which should be built around 2022. [19659002"TheChineseSpaceStation(CSS)doesnotbelongonlytoChinabutalsototheworld"saidShiZhongjunChina'sambbadadortotheUNandotherinternationalorganizationsVienna
"Thanks to the CSS vehicle, we would like to build a model of sincere and mutually beneficial cooperation between countries for the peaceful exploration and use of space."
Guided by the idea of a common future for humanity, the CSS will be an inclusive and open hearth, a home of peace and goodwill. , and a focus of cooperation for mutual benefit
Simonetta Di Pippo, Director of the United Nations Office for Space Affairs, welcomed this decision as China is ready to share its "advanced space program" ".
Li Guoping, a spokesman for the National Space Administration of China said that cooperation and international exchanges were needed to explore outer space.
For example, international consultations are needed to allocate satellite frequencies and orbital resources, as well as to formulate space traffic rules. continues the construction of an "information corridor" for countries along the road and belt, and a constellation of remote sensing satellites for the BRICS countries (Brazil, Russia, India, China and South Africa), said Mr. Li.
a speck of dust in the universe. Many astronauts and astronomers have expressed the opinion that those who see our blue planet of space have a deeper understanding of the fact that humans must learn to coexist on it.
