China's scientific and technological achievements in space since 2000.

Since 2000, China's major scientific and technological achievements in the space field include:

1. Shenzhou-1

Shenzhou-1 spacecraft is the first unmanned experimental spacecraft launched in China's manned space program. The spacecraft was launched from Jiuquan Space Launch Site at 6: 30 a.m. on1October 20, with the launch time of 1999 165438. The launch mission was undertaken by the Long March 2F manned space rocket on the basis of the Long March -2F bundled rocket.

Ten minutes after the launch and ignition, the ship and arrow separated and entered the scheduled orbit accurately. After the spacecraft was put into orbit, the measurement and control center on the ground and the survey ships distributed in the Pacific Ocean and the Indian Ocean tracked and controlled the spacecraft, and at the same time tested the life support system and attitude control system in the spacecraft.

Second, Tiangong No.1

Tiangong-1 is the first self-developed manned space test platform in China. It was launched from Jiuquan Satellite Launch Center at 2 1: 16: 03 on September 29th, 2065438, with a total length of 10.4m, a maximum diameter of 3.35m and an effective internal space of about 15m3.

Third, Dongfanghong No.1

Dongfanghong-1 satellite is the first artificial earth satellite launched by China. It was developed by China Academy of Space Technology, with Qian Xuesen as the first president, and was launched at 2 1970 at 0: 35 on April 24th. The successful launch of the 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 designed working life of the satellite is 20 days. In May 1970, the satellite stopped transmitting signals and lost contact with the ground. Because the perigee of Dongfanghong-1 satellite is high, Dongfanghong-1 satellite is still in orbit.

4. Shenzhou XI spacecraft

Shenzhou XI spacecraft is one of China Shenzhou series spacecraft, the sixth manned mission in China and the longest manned mission in China, with a total flight time of 33 days.

Shenzhou XI was launched from Jiuquan Satellite Launch Center at 7: 30 on June, 2065438 16+07, and then docked with Tiangong-2 to form an assembly. Two astronauts entered Tiangong-2 for a 30-day stay. During their in-orbit flight, they completed a series of space science experiments and technical experiments.

Five, the world's first quantum science experimental satellite "Mozi"

The Long March II carrier rocket successfully launched the world's first quantum experimental satellite "Mozi" into the sky, which will enable China to realize the quantum communication between satellite and ground for the first time in the world.

The first quantum communication satellite was named after Mozi, an ancient scientist in China. Mozi first put forward the viewpoint that light propagates along a straight line, and conducted pinhole imaging experiments. Named after him to commemorate his early achievements in physical optics. ?

Mozi discovered that light travels in a straight line for the first time through pinhole imaging experiments, and explained it scientifically for the first time-this is a very important principle in optics and laid a certain foundation for the development of quantum communication. Mozi also put forward a particle theory in a sense. The experimental satellite of optical quantum science is named after China sage Mozi, which reflects China's cultural self-confidence.
