    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
    .


    Just on December 29, 2021, it just finished its mission for the previous year, rested for more than half a month, and immediately began its "New Year's space journey"


    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
    .


    If you count the working time, Chang Erding is already a rocket with 30 years of service


    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"
    .


    What's so special about Chang Erding?

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


    Chang Erding commander-in-chief Tan Xuejun recalled that in the early 1990s, the situation of China's aerospace industry was very difficult, and Chang Erding's maiden flight in 1992 was under enormous pressure


    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 recent years, many "Internet celebrity" satellites have emerged among its "passengers", such as: dark matter particle detection satellite "Wukong", quantum science experimental satellite "Mozi" and so on


    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
    .


    With the first victory of Chang Erding's "good start", the launch of China Aerospace in 2022 officially kicked off
