2011165438+docked with Shenzhou-8 spacecraft in the early morning of1October 3. 20 12,18 (14:14: 04) successfully docked with Shenzhou 9 in the afternoon. Shenzhou-10 spacecraft also completed the automatic rendezvous and docking with Tiangong-1 on June 13 18.

On March 20 16 16, the Tiangong-1 target aircraft officially terminated its data service and fully completed its historical mission. The overall structure of Tiangong-1 is complete, and its running track is still under continuous and close monitoring. The average orbital height is about 370 kilometers, and it decays at the rate of 100 meters per day. 20 18 was "controlled" to fall, and the wreckage fell into the designated sea area.

On April 2, 20 18, around 8: 15, Tiangong-1 target aircraft re-entered the atmosphere, and the re-entry landing zone was located in the middle of the South Pacific. Most devices were ablated and destroyed during re-entry.

2. Xiaolong-Xiaolong

Jiaolong manned submersible is a manned submersible designed and independently developed by China, and it is also a major research project in the 863 Program. 20 10 From May to July, the manned submersible "Jiaolong" made several dives in the South China Sea of China, and the maximum dive depth reached 7020 meters.

In 2002, the Ministry of Science and Technology of China listed the development of deep-sea manned submersible as a major project of the national high-tech research and development plan (863 plan), and started the independent design and independent integrated development of Jiaolong manned submersible. From 2009 to 20 12, the sea trials of "1000m, 3000m, 5000m and 7000m were successively successful.

From June, 2065438 to June, 2002, China recorded a manned dive of 7062m in the Mariana Trench, which is also the largest dive depth record of its kind in the world. 20 14 12 18, diving in the Indian Ocean for the first time.

On June 4th, 2065 438+05 65438+ 10, the last dive of the first voyage of Indian Ocean scientific research was carried out in the hydrothermal area of Qi Long in the southwest Indian Ocean, which was also the ninth dive of this voyage. On March 6th, 17, the ship "Xiang Yanghong 09" docked at the dock of the National Deep Sea Base and officially settled in Qingdao. ?

On May 22nd, 20 16, the last scientific application dive of Yapu Trench was successfully completed, with the maximum dive depth of 6579 meters.

On March 4th and 7th, 20 17, the manned submersible Jiaolong made the third dive and the fourth dive in the first leg of China Ocean Voyage 38 in the silkworm 1 hydrothermal area and Daguan hydrothermal area respectively.

During the two dives, hydrothermal vents were found in the investigation area, and sulfide samples were obtained. On May 23rd, the "Jilong" completed its dive in the deepest part of the world. The submarine stayed underwater for nearly 9 hours, and the working time on the seabed was 3 hours 1 1 minute. The maximum diving depth is 48 1 1 m.

3. Tianyan-500m spherical radio telescope

The 500-meter spherical radio telescope, referred to as FAST, is located in Dawodang karst depression, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. This project is a major national science and technology infrastructure. The "Eye of the Sky" project consists of an active reflector system, a feed support system, a measurement and control system, a receiver, a terminal and an observation base.

The 500m spherical radio telescope is called "the 500m spherical radio telescope (FAST)", which was conceived by China astronomer Nan Zai 1994. It took 22 years to build and was put into use on September 25th, 20th16th. It is the largest single-aperture and most sensitive radio telescope in the world, which is led by the National Astronomical Observatory of Chinese Academy of Sciences and has independent intellectual property rights in China. The comprehensive performance is ten times that of the famous radio telescope Arecibo.

As of September 12, 2065438, 59 high-quality pulsar candidates have been discovered by the 500-meter spherical radio telescope, of which 44 have been confirmed as newly discovered pulsars. ?

2065438+In March 2009, Jiang Peng, chief engineer and researcher of FAST, National Astronomical Observatory of Chinese Academy of Sciences, said in an exclusive interview that with the cooperation of Tianma Telescope Team, joint observation was successfully realized for the first time, which indicated that FAST had the ability of joint network observation.

4. Wukong-Wukong Satellite

The Dark Matter Particle Detector (DAMPE) is one of the first four scientific experimental satellites developed by China Academy of Sciences in the strategic pilot science and technology project of space science. It is the dark matter particle detection satellite with the widest observation energy range and the best energy resolution in the world.

DAMPE is a space telescope with a payload of 14 10 kg, which can detect high-energy gamma rays, electrons and cosmic rays. It consists of plastic scintillation detector, silicon strip, tungsten plate, electromagnetic calorimeter and neutron detector.

The main scientific goal of DAMPE is to measure the proportion of positive and negative electrons in cosmic rays with higher energy and better resolution, so as to find out possible dark matter signals. It also has great potential to deepen human understanding of the origin and propagation mechanism of high-energy cosmic rays, and may also make new discoveries in high-energy gamma-ray astronomy.

At 20 15 12 17 8, China successfully launched the dark matter particle detection satellite "Wukong" with the Long March II carrier rocket at Jiuquan Satellite Launch Center. It has the advantages of high energy resolution, wide measurement energy range and strong background suppression ability, which promotes the detection of dark matter in China to a new level.

5. Mozi-Mozi satellite

Mozi quantum science experimental satellite was successfully launched by Long March II carrier rocket in Jiuquan on August 6, 20 16 1: 40. The successful launch of this mission marks another important step in China's space science research. ?

Academician Pan Jianwei, chief scientist of China Quantum Satellite, said that if the ground quantum communication has built a "network" connecting every city and every information transmission point, then the quantum science experimental satellite is like a "javelin" shooting this network into space. When this global quantum communication "heaven and earth network" is woven, massive information comes and goes in it, which is "unconditionally" safe.

On 20th1765438+1October18th, Mozi, the world's first experimental satellite for quantum science, successfully completed its four-month on-orbit test mission and was officially delivered to users. Relevant leaders of China University of Science and Technology, Chinese Academy of Sciences and other units signed the delivery certificate.

6. Large aircraft -C9 19 domestic aircraft

C9 19 large passenger plane, full name COMAC? C9 19 is the first trunk civil aircraft in China with independent intellectual property rights according to the latest international airworthiness standards, which was developed by Commercial Aircraft Corporation of China in 2008.

C is the initials of COMAC, a commercial aircraft company in China and China. The first "9" stands for eternity, and "19" stands for the maximum passenger capacity of China's first medium-sized passenger plane 190.

C9 19 large passenger plane is a large jet civil aircraft with independent intellectual property rights developed by China according to international civil aviation regulations. It has 65438 seats +058- 168 seats with a voyage of 4075-5555 kilometers. It successfully made its first flight on May 5, 20 17? As of February 26th, 20 18, we have received 8 15 orders from 28 customers. ?

2065438+081October 27th, 19 The second plane took off from Shengli Airport in Dongying, Shandong Province, and landed smoothly at Yaohu Airport in Nanchang after 2 hours and 6 minutes, successfully completing the transition flight mission. On February 28th, 20 18, the third C9 19 plane took off from the fourth runway of Shanghai Pudong International Airport and will complete its first flight.
