1. Long March 1 Rocket
Long March 1 (CZ-1) is a three-stage carrier rocket developed for launching China's first artificial satellite, with a length of 29.46 meters, a maximum diameter of 2.25 meters, a takeoff mass of 81.5 tons, and a near-Earth orbit (NEO) carrying capacity of 300 kilograms.
The development of the Long March 1 rocket began in 1965, and in November 1969, the first test flight of the Long March 1 rocket failed to enter orbit due to the failure of the second stage.
On April 24, 1970, China's first artificial Earth satellite, Dongfanghong No. 1, was successfully sent into space for the first time. The rocket *** conducted three satellite launches with a success rate of 66.67%, the third launch was in 1971.
2. Beidou Satellite Navigation Test System
Composed of various types of user machines. The center control system can carry out information ****sharing with other systems through the ground network, and can provide group users with the system data needed for command and control.
BeiDou satellite navigation test system can realize regional continuous navigation and positioning, short digital message communication and timing function. The BeiDou satellite navigation test system is also known as BeiDou-1.
It is the first-generation experimental system of the BeiDou satellite navigation system put into use earlier, using active positioning, consisting of three positioning satellites (two working satellites and one backup satellite), a ground control center-based ground part and user terminals.
BeiDou 1 satellite navigation and positioning system can provide users with all-weather instant positioning services. The calibration accuracy is 20 meters and the uncalibrated accuracy is 100 meters.
3, Tianhe-2 supercomputer
"Tianhe-2" is a supercomputer system developed by the National University of Defense Technology (NUDT), which tops the list with peak computing speed of 549 million times per second and sustained computing speed of 339 million times per second of double-precision floating-point operations with excellent performance.
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 title for the fourth consecutive time at a speed nearly twice as fast as the second-place U.S. "Titan". China's "Tianhe-2" won the title for the fourth consecutive time.
In May 2015, "Tianhe-2" successfully carried out 3 trillion particles of neutrinos and dark matter on the cosmological N-body numerical simulation, revealing the universe 16 million years after the Big Bang to the present about 13.7 billion years of the long evolutionary process.
At the same time, this is by far the world's largest particle number of N-body numerical simulation; November 16, the world's top 500 supercomputers list was announced in the United States, the "Tianhe-2" supercomputer with 33.86 trillion times per second for the sixth consecutive time to win.
June 20, 2016, a new issue of the world's top 500 supercomputers list was announced, the use of China's own chip manufacturing "Shenwei - Taihu Lake Light" to replace the "Tianhe II" on the top of the list.
On Nov. 12, 2018, a new list of the world's top 500 supercomputers was released in Dallas, U.S., with China's supercomputer "Tianhe-2" ranked fourth.
4, Mozi quantum communications satellite
In 2011, the Chinese Academy of Sciences officially launched the development of the world's first "quantum science experiment satellite", which means that Chinese scientists take the lead in launching a challenge to the star and the ground quantum communications, but also means that China may be ahead of the United States and Europe to get the ability to cover the world with quantum communications.
China's launch of the world's first quantum science experiment satellite was officially named "Mozi". Pan Jianwei, chief scientist of the quantum satellite, said Mozi first proposed that light travels in a straight line.
Designed the small hole imaging experiment, laid the foundation for optical communication, quantum communication. Naming the quantum satellite after a great ancient Chinese scientist will boost our cultural confidence.?
At 1:40 p.m. on Aug. 16, 2016, China successfully launched the world's first quantum science experiment satellite (QSES) from the Jiuquan Satellite Launch Center on a Long March 2-D carrier rocket.
5, Xue Long Polar Research Vessel
Xue Long Polar Research Vessel referred to as "Xue Long" (English name: Xue Long), China's third-generation polar icebreaker and scientific research vessel, is a Vitas Bering-class icebreaker built by the Ukraine Kherson Shipyard on March 25, 1993, completed construction. Icebreaker.
China imported it from Ukraine in 1993 and then modified it to meet Chinese needs. "The Xuelong is China's largest polar research vessel and the only Chinese ship capable of breaking ice in the polar regions.
The Xuelong is a cold-resistant ship that can continuously break through 1.2-meter-thick ice (including 0.2-meter snow) at a speed of 1.5 knots.
The Xuelong has been to the South Pole for 31 times since its first expedition to the South Pole in October 1994 and has been transporting supplies.
To July 2014, it has gone to the Arctic six times to carry out scientific research and supply and transportation tasks, footprints throughout the five oceans, creating a number of new records in China's maritime history.
On March 11, 2018, China's 34th Antarctic research team, which is carrying out a comprehensive marine survey mission in the Amundsen Sea and nearby waters of Antarctica, went deep into the central waters of the westerly wind belt and the cyclone-influenced area aboard the polar research vessel Xuelong, and obtained full-depth cross-section observations of the core area of the Antarctic circum-polar current.
