Why is Chang Er Ding, who has played the important role in his debut, called the "Golden Rocket"?

At 10:35 on January 17, Beijing time, China successfully launched the test satellite No.
13 with the Long March 2D carrier rocket (referred to as: Changer Ding) at the Taiyuan Satellite Launch Center
.

"Hold up" China Aerospace's 2022 launch is the "golden rocket" Changerding
.

Working age: 30 years of hard work is not easy to grow

The Changerding carrier rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation.
It was established in 1990 and flew for the first time on August 9, 1992.
This launch is its 58th launch
.

But since the world's first launch vehicle was launched in 1957, there are now about 80 to 90 launch vehicles in the world each year to start "space transportation"
.

In the Chinese aerospace industry, it is well known that the first three launches of Changerding were not easy
.

Under such a big background, it was not easy for Changerding to achieve three consecutive successes, so it was awarded the title of "high-quality launch vehicle"
.

Skills: Reliable vehicles frequently send "net red" satellites

Changerding is a normal-temperature liquid two-stage launch vehicle with a take-off thrust of 300 tons and a carrying capacity of 1.
2 tons corresponding to a 700-kilometer sun-synchronous circular orbit
.

The reliability index of Changer Ding's full rocket is as high as 0.
97, which is outstanding in the "world launch vehicle family", so it was awarded the title of "Golden Rocket"
.

As China's aerospace industry continues to grow, the Changerding carrier rocket is also very busy
.

In 2022, China Aerospace Science and Technology Corporation plans to arrange more than 40 space launch missions, will complete 6 major manned space missions, fully build the Chinese space station, and complete the first flight of the Long March 6A carrier rocket
