December 9, 2023, will be a day recorded in the annals of space history. China's Zhuque II Yao-3 carrier rocket successfully launched once again from the Jiuquan Satellite Launch Center, sending the Hongyun satellite, Tianyi 33 satellite, and Hongyun II satellite into their designated orbits in one go. This not only marks the world's first successful satellite launch by a methane rocket but also signifies the beginning of the methane rocket era. Dear audience, welcome back to our channel!

This day's arrival is undoubtedly exhilarating news for all those interested in space technology. The successful launch of China's Zhuque II Yao-3 carrier rocket not only demonstrates a significant breakthrough in China's space technology but also signifies a milestone in China's reusable rocket technology, with far-reaching implications.

This day will be etched in the annals of world aerospace history as China's pride—Zhuque II Yao-3 carrier rocket—successfully completes its mission once again at the Jiuquan Satellite Launch Center. This flight mission successfully deployed the Hongyun, Tianyi 33, and Hongyun II satellites into their respective target orbits with precision.
The methane rocket launched this time becomes the world's first successful satellite-launching rocket of its kind, ushering in a new era of global aerospace and marking a breakthrough in rocket technology using methane as fuel. Thanks to the reusable nature of methane rocket engines, this launch also symbolizes a crucial step forward for China in developing reusable rocket technology, showcasing our new advancements in aerospace technology.
Methane, as a simple hydrocarbon with the chemical formula CH4, is not only the primary component of natural gas used in our daily cooking but also a major component of flatulence produced by humans and certain animals through digestion. This colorless, odorless gas has a high calorific value; when burned, it releases a large amount of energy, ultimately converting into carbon dioxide and water vapor, both relatively harmless gases to the environment, thus not causing air pollution.
With the increasing global demand for clean energy, methane has found wide applications in modern society, particularly in agricultural production and people's daily lives, due to its clean and efficient combustion. Facilities and equipment using methane as energy can significantly reduce environmental burdens, especially when replacing some traditional fossil fuel-based energy sources, effectively lowering greenhouse gas emissions.
In the aerospace field, the use of methane also presents significant advantages. The practice of combining liquid oxygen and methane as rocket propellants is changing the face of space propulsion technology. Compared to traditional rocket fuels such as kerosene or liquid hydrogen, methane not only has a higher energy density but also primarily releases carbon dioxide and water during combustion, making it a cleaner option for rocket fuel.
