Have you noticed it? In recent years, China Aerospace has entered a "thriving" stage, and has launched several extraordinary space projects. The completed China Space Station , Chang'e 6, which plans to dig soil on the moon again, and Mars rover , which is preparing to return for Mars sampling, will all be recorded in history.
In the field of rocket launches, China is also getting stronger and stronger. China's rocket launches have exceeded the United States. In 2021, my country's rocket launches reached 55 times. Every few days, a Chinese rocket launches took off, surpassing the United States, which has only 51 times in 2021.
No wonder NASA Director Jim Bradenstine is worried about one thing: China's spacecraft may soon surpass US space, and has repeatedly talked about the Chinese space station and Zhurong Mars rover , taking photos of Zhurong Mars rover to ask Congress for money, and throwing money from space.
In fact, Bradenstine's concerns are not redundant. In the last century, the US aerospace entered the "most glorious" period. The Apollo moon landing plan is indeed not as good as before. Before 2022, my country's rocket launches reached 56 times, which can be said to be a new high and it is very likely to surpass the United States.
However, in the field of commercial launch, China's aerospace still has to learn from the United States. The SPACEX company almost monopolizes the commercial rocket launch market. The satellite of many countries has been launched with Musk. The Falcon 9 rocket is also rumored by people to be magical and is regarded as the strongest rocket in the world.
In order to open up the commercial launch market, my country is also striving to build commercial rockets and develop many private rocket companies. On December 9, 2022, the commercial rocket Jetlong-3 created by China Long March Rocket Company soared into the sky, with 14 stars in one shot, including Jilin No. 1 high score 03D47-50 stars, Dongpo 08-10 stars, etc.
This is the first launch of the Jetlong-3 rocket. This is also the first time that the Jetlong-3 rocket has launched from sea and launched from the launch ship in the Yellow Sea waters. Sea launch has always been a world-class problem, but Jetlong-3 successfully sent all 14 satellites into the expected orbit. The photos on the scene show that the launch ship is surrounded by deep blue sea water.
Do you know how strong Jielong No. 3 is? So let’s learn how strong it is. Jetlong III is a commercial rocket specially created by China’s Long March Rocket Company for the commercial aerospace launch market. Jetlong One and Jetlong II are brothers. These three models can be said to be the pride of China’s aerospace industry.
Jetlong-3 rocket is a small rocket with a weight of only 31 meters. The maximum diameter of the arrow body is 2.65 meters, the minimum diameter is two meters. The take-off mass is 140 tons. 71 tons of solid fuel is solidified inside the arrow body, with a thrust of 200 tons. It can send a load of 1.5 tons to a 500-kilometer-high solar synchronous orbit.
From the photo, the head of the Jetlong-3 rocket is very large, giving people a head-heavy feeling. This is because the interior space of the Jetlong-3 rocket fairing is very large, and it can be equipped with more satellites at one time, and can be shot 20 stars in one shot, so this time it is a tiny idea.
Although the Jetlong-3 rocket is a small rocket, it adopts a four-stage solid tandem configuration, which can be said to be great. The Jetlong-3 rocket has a very cost-effective performance. The launch cost of a kilogram of load is less than 10,000 US dollars. For example, launching a satellite with a mass of 1 ton is less than 10 million.
In short, the Jetlong 3 carrier rocket has very strong carrying capacity, so it has extremely strong market competitiveness. In the commercial launch field of small satellite , it can compete with Musk's Falcon 9 rocket. The future is immeasurable and it will definitely have a place in the future.
In addition, my country is also developing stronger commercial rockets. For example, the domestic private rocket enterprise Blue Arrow Aerospace Zhuque 2 Yao-2 rocket is being installed and will be launched in early 2023. Zhuque 2 will use the vacuum liquid oxygen methane engine (TQ-15A) thrust up to 836kN.
