“I am Shuguang” and “Shuguang understands” shocked the entire Internet. Who is “Shuguang”?

August 20, 14:33

After about 6 hours of extravehicular activities, astronauts Nie Haisheng and Liu Boming returned safely to the core module of the space station. The second extravehicular activity was a complete success. In the news broadcast by CCTV, a voice codenamed "Shuguang" congratulated the astronauts. The strength and confidence conveyed by the firm and decisive voice deeply shocked the majority of netizens. So who is "Shuguang"? Why was this codename named "Shuguang"? Next, Xiao Tai will talk to you about the "past and present" of "Shuguang" in the aerospace industry. "Shuguang"

It was the name of my country's first manned space program.

Early 1970s

China begins research in manned space flight

In the words of Qian Xuesen at the time

Let’s start the manned space flight campaign

The researchers at that time

Not only did they design and produce exquisite spacecraft drawings and models,

And gave the spacecraft a nice name.

Dawn-1

However, due to the weak economic foundation of my country at that time and the low level of industrial manufacturing and related technology, the "Dawn" spacecraft was eventually sealed in the concept drawings and experiments. Its beginning and end were like a lighthouse that illuminated the sky in an instant, guiding the trajectory of the "Shenzhou" manned spacecraft.

This period is an attempt to build on the dream

Although it was eventually shelved due to insufficient technology and national strength limitations

But this brave attempt in the passionate era

Represents the most simple Chinese

Flying Dream

"Dawn"

It is the guide for astronauts on the ground.

now

For astronauts in orbit, "Dawn" means the full support of astronaut system personnel on the ground hundreds of kilometers away. During the extravehicular activities in the space station phase, it is "Dawn" that guides astronauts every step of their walk in space.

"I am Shuguang." "Shuguang understands!" During the astronauts' extravehicular mission, the ground support team will communicate directly with the astronauts through the "Shuguang Post" to help the astronauts enter the node module from the core module.

The entire process was commanded by "Shuguang" until the EVA mission was completed and the core module was returned and the hatch was closed.

During the second spacewalk on August 20, the ground-based Shuguang Post called out to the two astronauts at about 11:10 a.m. that they could take a photo of each other. "01, can you raise your head a little?" "Can you turn on the space suit lights?" "Okay, sure, beautiful!" With close cooperation between the ground and the space, Nie Haisheng and Liu Boming pointed their cameras at each other and captured a rare scene.

The password was sent by one person

In fact, "Shuguang" represents a cross-system and cross-departmental extravehicular activity support team, which covers the astronaut system, space station system and measurement and control system.

As the person who remotely controls the spacewalk, the tacit cooperation between "Shuguang" and the astronauts is an important prerequisite for the success of the spacewalk.

Through long-term and extensive ground training, from the interactive commands between the ground and the sky to the interaction between each operation action, "Shuguang" and the astronauts know each other very well.

"Shuguang" was once the spark of China's manned space program

Lighting up the Chinese people's dream of flying

Today, the Chinese nation's dream of flying

It has become a reality with the launch of Shenzhou

"Shuguang" will also continue to illuminate the direction of China's space station
