China’s scientific and technological achievements in aerospace since 2000

China’s major aerospace science and technology achievements since 2000 include:

1. Shenzhou-1

The Shenzhou-1 spacecraft is the first and national satellite of the Chinese people. The first unmanned experimental spacecraft launched in the human space program. The spacecraft was launched from the Jiuquan Space Launch Site at 6:30 a.m. on November 20, 1999. The launch mission was based on the Long March-2F strap-on rocket. The Long March 2F manned space rocket developed by Shanghai.

Ten minutes after launch and ignition, the ship and arrow separated and accurately entered the planned orbit. After the spacecraft entered orbit, various measurement and control centers on the ground and survey ships distributed in the Pacific and Indian Oceans tracked and controlled the spacecraft. At the same time, the life support system and attitude control system in the spacecraft were also tested.

2. Tiangong-1

The Tiangong-1 target aircraft is China’s first independently developed manned space test platform. It was launched at 21:16:03 on September 29, 2011. Launched from the Jiuquan Satellite Launch Center, it has a total length of 10.4 meters, a maximum diameter of 3.35 meters, and an effective internal space of about 15 cubic meters, which can meet the work and living needs of three astronauts in the cabin. It is designed to have a two-year orbital life.

3. Dongfanghong-1

Dongfanghong-1 is the first artificial earth satellite launched by China. It was developed by the China Academy of Space Technology with Qian Xuesen as its first director. Developed independently, it was launched at 21:35 on April 24, 1970. The successful launch of this satellite marks that China has become the fifth country in the world to launch a domestic satellite with a homemade rocket after the Soviet Union, the United States, France, and Japan.

The satellite was designed to have a working life of 20 days. It stopped transmitting signals on May 14, 1970 and lost contact with the ground. Due to the high perigee altitude of the Dongfanghong-1 satellite, the Dongfanghong-1 satellite is still in orbit.

4. Shenzhou-11 spacecraft

The Shenzhou-11 spacecraft is one of China’s Shenzhou series of spacecrafts. It is China’s sixth manned mission and the longest in China’s history. The longest manned mission, the total flight time was 33 days.

Shenzhou-11 was launched from the Jiuquan Satellite Launch Center at 7:30 on October 17, 2016, and then docked with Tiangong-2 to form a combination. Two astronauts stationed in Tiangong-2 and conducted During the 30-day stay in orbit, a series of space science experiments and technology tests were completed.

5. The world’s first quantum science experimental satellite “Mozi”

The Long March 2D carrier rocket successfully launched the world’s first quantum experimental satellite “Mozi” into the sky , which will enable our country to realize quantum communication between satellites and the ground for the first time in the world.

The first quantum communication satellite is named after the ancient Chinese scientist Mozi. Mozi first proposed the idea that light propagates along straight lines and conducted small hole imaging experiments. Named after him to commemorate his achievements in early physical optics. ?

Mozi was the first to discover that light propagates in a straight line through a small hole imaging experiment, and for the first time scientifically explained the straight-line propagation of light - this is a very important principle in optics and provides the basis for quantum The development of communications has laid a certain foundation. Mozi also proposed a particle theory in a certain sense. The optical quantum science experimental satellite is named after the Chinese scientist Mozi, which reflects China's cultural confidence.
