When was Shenzhou 5 built 5

It was officially completed on 10 October 2003.

Introduction to Shenzhou 5.

In order to enable astronauts to have a comfortable and safe environment in the return capsule, the developers finally selected a low-density ablative heat-proof material after many experiments, so that the outside of the spacecraft can still be kept at about 20 degrees above minus 20 degrees even when it is minus 100 degrees to minus 3000 degrees. ”

There are many more original technologies like this in the development of the Shenzhou spacecraft. As China's first generation of manned spacecraft, Shenzhou 5 has surpassed the design of single cabin and double cabin, and directly adopted a multi-functional spacecraft scheme composed of three cabins. Although Shenzhou 5 only carried one astronaut this time, we designed it to carry three people at the same time.

Qi Fayun, chief designer of the Shenzhou spacecraft: (Shenzhou) The spacecraft started relatively late, but our starting point is relatively high, and we have done it in one step. Where is it, we have adopted 3 cabins at once, and added an additional section such a layout, so that our ship can be transported back and forth between heaven and earth at once.

After the astronauts return to the ground, the orbital module of the Shenzhou-5 spacecraft will work autonomously in space like a satellite under unattended conditions, which greatly extends the working life of the spacecraft in carrying out space applications and scientific experiments.

The return capsule of the Shenzhou 5 spacecraft is meters high, equivalent to a six-square-meter room, and is currently the largest spacecraft return capsule in the world. In order to ensure the safe return of the three-ton return capsule to the ground, the research and development personnel also specially designed the world's largest return landing parachute with an area of 1,200 square meters when the spacecraft landed and decelerated, so that the landing speed of the return capsule was reduced by more than 20 times in more than 10 minutes.

Lu Yongxiang, President of the Chinese Academy of Sciences: This shows that China's aerospace industry is no longer at an ordinary level, but has entered the advanced ranks of the world, and its reliability, carrying capacity, control system, and safety guarantee system have all reached the top three positions in the world.

China's self-developed "Shenzhou-5".

The manned spacecraft at the Jiuquan Satellite Launch Center.

By the "Long March. The No. 2F rocket was successfully launched, and China's first astronaut was successfully sent into space.

The spacecraft orbited the earth 14 times, flew safely for 21 hours and 23 minutes, 600,000 kilometers, and successfully landed at the main landing site in Inner Mongolia at 6:23 on the 16th. The successful launch of the "Shenzhou-5" manned spacecraft indicates that China has become one of the countries in the world that has independently and completely mastered manned space technology.

Value significanceThe Shenzhou-5 manned space mission has fulfilled the Chinese nation's desire to fly to the sky for a thousand years, is a high degree of cohesion of the wisdom and spirit of the Chinese nation, and is a new milestone in China's space industry in the new century.

The successful launch of Shenzhou-5 marked China's succession to the former Soviet Union.

Russia) and the United States, the third country to independently master manned space technology.

The successful launch of Shenzhou-5 was on October 15, 2003.

On October 15, 2003, China developed its own Shenzhou 5 manned spacecraft.

Successfully launched at the Jiuquan Satellite Launch Center, Chinese astronaut Yang Liwei.

was sent into space. After completing a series of action commands, through the glass window of the rough spaceship, he finally saw the scenery he had always dreamed of.

R&D process. The Shenzhou-5 manned space mission is mainly to assess the manned environment of the project, obtain the relevant data of the astronauts' space living environment and safety, and evaluate the working performance, reliability, safety and coordination between the rocky systems of the project.

The spacecraft flew with an astronaut for about a day, returning on the 14th lap of its orbit around the Earth. Astronauts can manually reissue important instructions such as ship and arrow separation and sail boards in accordance with pre-specified procedures and ground instructions.

The spacecraft has the ability to make an autonomous emergency return and manually controlled return, as well as return on the second and third days.

Shenzhou-5 was successfully launched on October 15, 2003.

The Shenzhou-5 spacecraft carried astronaut Yang Liwei was launched at the Jiuquan Satellite Launch Center at 9 o'clock on October 15, 2003, Beijing time, flew 14 laps in orbit, lasted 21 hours and was closed for 23 minutes, and after successfully completing all the scheduled operational tasks, its return capsule returned to the main landing site of Mongolia at 6:23 on October 16, 2003, Beijing time, and its orbital module remained in orbit for half a year.

The complete success of the Shenzhou-5 mission marks that China has become the third country in the world to independently master manned space technology, has realized the Chinese nation's dream of flying into the sky for thousands of years, is a high degree of cohesion of the wisdom and spirit of the Chinese nation, and is a new milestone in China's space industry in the 21 st century.

System Composition:

Spacecraft system: The Shenzhou-5 spacecraft consists of a propulsion module, an orbital module, a return module, and an additional stage. Its head is a cylinder, while the head of No. 4 is a hemispherical body, and there are only astronauts in the spacecraft cabin, and the plane of its space is about meters, less than 6 square meters, and can accommodate three astronauts.

In addition, the Shenzhou-5 spacecraft also retains an interface for docking with the space laboratory.

Rocket system: The launch mission of the Shenzhou-5 spacecraft is undertaken by the Long March-2F carrier rocket, which consists of four boosters, a first stage, a second stage, a fairing and an escape tower, with a total length of meters; Take-off mass tons. The upper fairing of the rocket, the escape tower, the orbital module of the spacecraft, and the return capsule constitute the escape vehicle.

Carrying items: The Shenzhou-5 spacecraft carries items including: a Chinese flag with special significance, a flag of the emblem of the Beijing 2008 Olympic Games, a United Nations flag, a sample of the main currency of the People's Imperial Forest, a commemorative stamp of China's first manned space flight, a commemorative cover of China's manned space program, and crop seeds from Taiwan, the treasure island of the motherland.
