The development of China’s manned space industry

In 1992, my country's manned spacecraft was officially included in the national plan for development. This project was later named the "Shenzhou" spacecraft manned space project.

Shenzhou-1

In the early morning of November 21, 1999, Beijing time, the first test spacecraft launched by my country, "Shenzhou 1", successfully landed in central Inner Mongolia after completing its space flight test.

On January 10, 2001, China's self-developed "Shenzhou" 2 spacecraft was successfully launched from the Jiuquan Satellite Launch Center.

Shenzhou 6 successfully launched

Two years after the successful launch of Shenzhou-5, on October 17, 2005, China conducted its second manned space flight. Chinese astronauts Fei Junlong and Nie Haisheng successfully entered space.

summary

From the successful launch of the first Chinese man-made satellite to the later Shenzhou 7, China's aerospace history has gone through 38 years. China has grown from a weak space country to a powerful space country.

my country's lunar exploration program "Chang'e-1"

China's lunar exploration plan will be implemented in three phases.

The first phase is to launch a lunar exploration satellite to the moon in the next 2 to 3 years.

In the second phase, a lunar probe will be launched to land on the moon.

The third phase will launch robots to the moon. The planning took approximately 20 years.

first round

On October 4, 1957, the Soviet Union successfully launched the world's first artificial earth satellite. In this regard, Teller, the father of the hydrogen bomb, once said sadly: The United States lost a "battle more important than Pearl Harbor."

second round

On April 12, 1961, Gagarin flew around the Earth in the Vostok spacecraft for 108 minutes. At the Kennedy Space Center in the United States, a dummy draped in an American flag died together with a rocket that self-destructed and exploded.

round three

On July 16, 1969, Americans finally felt proud for once. The Apollo 11 spacecraft successfully landed on the moon and returned safely.

The Soviet Union lost its leading position in the space competition with the United States.

How much do you know about space disasters?

January 1967: Three American astronauts died when the spacecraft caught fire during a simulated launch of the Apollo 1 spacecraft.

In April 1967, when the Soviet Soyuz 1 spacecraft passed the final hurdle, the parachute rope of the parachute became entangled and the parachute could not be opened. The return capsule rushed to the ground at an extremely high speed, causing the ship to crash and killing everyone. Became the first astronaut in the world to die during a space mission.

July 1971: After 24 days of working in the space laboratory, three former Soviet cosmonauts on board the Soviet Soyuz 11 spacecraft suddenly lost pressure in the cabin due to a leak in a valve during their return to the ground. The member suffocated to death.
