At this year’s central economic work conference, the requirements of “strengthening the national strategic scientific and technological force and giving full play to the role of the National Laboratory” were specifically mentioned. As of December 28, 2021, China’s space launches had 53 times and succeeded 50 times. Shenzhou chased dreams, roamed the heavenly palace and explored fire in heaven. These achievements have condensed the efforts inherited by astronauts from generation to generation. In these major projects, A group of post-90s young people began to emerge.
Let astronauts use satisfactory control equipment
The post-90s girl did
On April 29, 2021, the Long March 5 B yao-2 carrier rocket carrying the space station Tianhe core module was launched from Wenchang space launch site in Hainan. China’s manned space station construction officially entered the fast lane. In the future, the two experimental modules of Wentian and Mengtian will also successively land in space and dock with Tianhe core module. Astronauts can stay on the space station for more than one year.
At that time, China will become the country that will complete the construction of the space station alone after Russia, which also marks the opening of the curtain of China’s space station construction. At the China Academy of space technology, the reporter met Wu Wen, a member of the post-90s Aerospace regiment.
Wu Wen, born in 1990, is now the chief designer of the instrument and lighting subsystem of the space station.
On December 9, the “Tiangong classroom” was broadcast. Behind the “space teacher” Wang Yaping, several control devices of different sizes were designed by Wu Wen and his team. When they first designed it, their first goal was to “turn complexity into simplicity”.

The three astronauts Zhai Zhigang, Wang Yaping and ye Guangfu will work and live in the space station for six months, and they will not feel the changes of day and night in space.
Therefore, Wu Wen’s team should fully consider the different scenes of astronauts’ work and life at the beginning of the construction of the space station, and have corresponding light color adjustment when astronauts sleep and eat.
Today, the operating system in the space station is still iterating and upgrading. participated in six satellite launches in 7 years This post-90s design saved the country tens of billions of yuan
So far, China’s annual rocket launch in 2021 ranks first in the world. In addition to the famous “Tianhe” and “Tianwen”, another sharp weapon of China’s Aerospace – “Gaogao satellite” series No. 3 02 satellite was also successfully launched on November 23.
High resolution satellites are mainly used for earth observation. A total of 7 satellites are planned, of which Gaogao 3 is the only radar satellite among the 7 satellites. Before that, China had no C-band synthetic aperture radar satellite with a resolution of 1m.
As a generalist who can “see the earth and explore the sea”, gaogao-3 satellite has released more than 1.8 million pieces of data to all walks of life after entering the predetermined orbit.
At present, the development of Gaogao satellite 03 is being carried out synchronously. In the future, the three-star networking means that Gaogao 3 will obtain more data and faster under the same conditions.
Zhang Chi is also a post-90s generation. He is the chief designer of AIS system of gaogao-3 02 satellite development team of China Academy of space technology. Zhang Chi, born in 1990, is already a “veteran” in the field of satellite development.
During the development of Gaosan 02 satellite, the ship automatic identification system, referred to as “AIS”, is added. Zhang Chi is mainly responsible for the design and construction of this new system. In contrast, this is a set of receiving equipment with low frequency and high sensitivity. For Gaosan 02 satellite with giant antenna, the electromagnetic interference generated by itself will greatly interfere with “AIS” equipment. How to make a variety of electromagnetic compatible with each other is a difficult problem in front of Zhang Chi.
On November 28, 2021, when the first clear high-resolution image is transmitted back to the ground from the satellite, it means that all parameters and indicators of the satellite meet the design requirements of the team.
At present, the imaging mode, resolution and width of gaogao-3 dual satellite network are the most comprehensive radar satellites in the world.
2021 marks the 65th anniversary of the founding of China’s aerospace industry. From “two bombs and one satellite” to “Shenzhou” manned, from “Beidou” to “Chang’e” to the moon and “Tianwen” to explore fire, from cabin experiment to spacewalk, China’s aerospace industry is making a step by step to refresh the “China height” in the vast space.
For these post-90s astronauts, 2021 is also a year full of harvest. In the future, Chinese astronauts will make persistent efforts and create greater brilliance.
[half hour observation] Chinese astronauts continue to struggle and make solid progress
Exploring the vast universe is the common dream of all mankind, and the construction and operation of space stations in low earth orbit is not only an important symbol to measure a country’s economy, science and technology and comprehensive national strength, but also a test of a country’s strength. From 1970 when the first man-made earth satellite “dongfanghong-1” was launched into the predetermined orbit to 2021 when three astronauts realized their dreams of the Chinese space station, China’s aerospace is embarking on a new journey. Generations of spacefaring people continue to inherit, continue to struggle, and never stop. We praise the astronauts and the post-90s tiantuan. With them, the Chinese people’s pace of exploring space will be bigger and farther.
