1. Long March 1 rocket
The Long March 1 (CZ-1) is a three-stage carrier rocket developed to launch China's first artificial satellite. It has a total length of 29.46 meters. The maximum diameter is 2.25 meters, the take-off mass is 81.5 tons, and the low-Earth orbit carrying capacity is 300 kilograms.
The development of the Long March-1 rocket began in 1965. In November 1969, the Long March 1 rocket made its first test flight, but failed to enter orbit due to a second-stage failure.
On April 24, 1970, China’s first artificial earth satellite, Dongfanghong-1, was successfully launched into space for the first time. The rocket has carried out three satellite launches, with a success rate of 66.67%. The third launch was in 1971.
2. Beidou Satellite Navigation Test System
It is composed of various types of user computers. The central control system can share information with other systems through the ground network, and can provide group users with system data required for command and control.
The Beidou satellite navigation test system can realize regional continuous navigation and positioning, short digital message communication and timing functions. The Beidou satellite navigation test system is also called Beidou-1.
It is the first-generation experimental system of Beidou Satellite Navigation System that was put into use earlier. It uses active positioning and consists of three positioning satellites (two working satellites and one backup satellite) ground control center. It consists of three parts: the main ground part and the user terminal.
The Beidou-1 satellite navigation and positioning system can provide users with all-weather real-time positioning services. Calibrated accuracy is 20 meters, uncalibrated accuracy is 100 meters.
3. Tianhe-2 supercomputer
"Tianhe-2" is a supercomputer system developed by the University of Defense Technology. It has a peak computing speed of 549 petaflops per second and a continuous The computing speed of 339 petaflops of double-precision floating point operations ranks first in the list.
Became the world’s fastest supercomputer in 2013. In the list of the world's top 500 supercomputers announced on November 17, 2014, China's "Tianhe-2" won the championship for the fourth consecutive time at a speed nearly twice as fast as the second-place American "Titan".
In May 2015, the "Tianhe-2" successfully conducted a cosmological N-body numerical simulation of neutrinos and dark matter with a particle number of 3 trillion, revealing that about 16 million years after the Big Bang, the universe has A long evolutionary process of 13.7 billion years.
At the same time, this is the N-body numerical simulation with the largest number of particles in the world so far; on November 16, the list of the world's top 500 supercomputers was announced in the United States. The "Tianhe-2" supercomputer ran at 33 ．86 quadrillion times to dominate for the sixth time in a row.
On June 20, 2016, the new list of the world's top 500 supercomputers was announced, with "Sunway TaihuLight" manufactured using China's own chips replacing "Tianhe-2" at the top of the list.
On November 12, 2018, the new list of the world's top 500 supercomputers was released in Dallas, USA. China's supercomputer "Tianhe-2" ranked fourth.
4. Mozi Quantum Communication Satellite
In 2011, the Chinese Academy of Sciences officially launched the development of the world's first "quantum science experimental satellite", which means that Chinese scientists are the first to launch satellite-based The challenge of quantum communication means that China may be ahead of Europe and the United States in obtaining the ability of quantum communication to cover the world.
The world's first quantum science experimental satellite launched by my country was officially named "Mozi". Academician Pan Jianwei, chief scientist of quantum satellites, said that Mozi first proposed that light propagates in straight lines.
Designed a small hole imaging experiment, laying the foundation for optical communication and quantum communication. Naming quantum satellites after great ancient Chinese scientists will enhance our cultural confidence. ?
At 1:40 on August 16, 2016, my country successfully launched the world's first quantum science experiment satellite (referred to as "Quantum Satellite") using the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center. null.
5. Xue Long polar research ship
The Xue Long polar research ship, referred to as "Xue Long" (English name: Xue Long), is China's third-generation polar icebreaker and scientific The research ship is a Vitus Bering-class icebreaker completed by the Kherson Shipyard in Ukraine on March 25, 1993.
China imported it from Ukraine in 1993 and then transformed it according to China's needs. The "Snow Dragon" is China's largest polar research ship and the only Chinese ship that can break through polar ice.
The Snow Dragon boat is cold-resistant and can continuously break through 1.2 meters of ice (including 0.2 meters of snow) at a speed of 1.5 knots. The first Antarctic scientific expedition and material supply transportation was carried out in October 1994. The "Snow Dragon" has visited Antarctica 31 times.
As of July 2014, it has gone to the Arctic six times to carry out scientific expeditions and supply transportation missions, covering all five oceans, and setting many new records in China's navigation history.
On March 11, 2018, China’s 34th Antarctic scientific expedition team, which was performing a comprehensive marine survey mission in the Amundsen Sea and nearby waters of Antarctica, boarded the polar research vessel "Snow Dragon" and went deep into the westerly zone. In the central sea area and cyclone influence area, full-depth cross-sectional observation data in the core area of ??the Antarctic Circumpolar Current were obtained.
