Sorry to disappoint the beauty, after Beidou completed the last step, 2 good news came out of China

Recently After the completion of the last step of the Beidou system networking, China has heard two good news within 72 hours, that is, the Long March 4B and the Long March 2D D carrier rockets were successively lifted off, and the three types and uses were different. The satellites sent into space, the signal conveyed by this move is extraordinary, reflecting the fact that the Chinese aerospace community has normalized the launch activity. Some netizens said that this is China’s real strength, and I am embarrassed to let Americans disappointed.

Behind the increasing frequency of space launch activities, it reflects the rapid progress of Chinese carrier rocket technology in the past half century. Just 50 years ago, China first sent the independently developed Dongfanghong-1 satellite to space. At that time, it used the Long March 1 carrier rocket, which was actually removed on the basis of liquid fuel medium-range ballistic missiles. The reentry unit and the warhead, and the addition of a third stage using solid propellant, is relatively simple in terms of technology and its load capacity is relatively limited. It can only launch light test satellites.
Since then, China has continued to improve the Long March 2 series of launch vehicles on the basis of liquid fuel intercontinental ballistic missiles, and used them to complete the launch test mission of multiple return satellites. On the basis of the No. C type, a different third stage was installed, and the Long March 3 and Long March 4 series rockets were developed separately. It is worth mentioning that the Long March 2 series has developed to eight subtypes today, including Starting from the Long March 2 D, it is actually a development type of the Long March 4 A. The basic design has changed a lot. The later models are equipped with a bundled booster engine. The Long March 2 F in this series has long been responsible for China. Human space missions, and all succeeded.

If you mention the gold rocket in the hands of the Chinese aerospace industry, many netizens can say the name of the Long March 3 series, of which the Long March 3 B is even more outstanding, in 68 launch missions of this type of rocket Among them, there were only 2 failures and 2 incomplete success records. The rest of the launches were a complete success. For this reason, they also undertook the launch of the Beidou system networking satellite for a long time. Recently, this type of rocket also successfully sent the Asia-Pacific 6D communication satellite to the earth. Simultaneously shift the track and wrote another brilliant victory.
Of course, the most eye-catching among the Chinese launch vehicle family is the Changzheng No. 5, commonly known as fat five, as China The first heavy-duty launch vehicle independently developed, which uses a new type of liquid hydrogen liquid oxygen fuel, which is non-toxic and harmless to the natural environment. The earth orbit capacity reaches 25 tons, and the geosynchronous transfer orbit capacity reaches 14 tons. Whether it is launching a space station module, a new generation of manned spacecraft or a planetary probe, it is handy, so it has been expected from the day of its birth, despite its development There have been small twists and turns on the road, but it has matured and more launch missions carried out by it have been put on the agenda.

Looking back, China’s launch vehicle business has achieved from scratch and continued exploration and frustration through military-to-civilian transformation It has grown vigorously, and now it has made China no longer subject to all aspects of the space launch business. This is undoubtedly worthy of our pride. With the maturity of a series of subsequent models such as the Long March 7th and 8th, 9th, China carried The Rockets family must have a brighter future.
