Early this morning, the Long March 3B carrier rocket successfully launched the 25 satellite, which also made China's space launch mission a "good start" in 2025.

The Long March 3B carrier rocket is mainly used to launch high-orbit spacecraft. The practice satellite launched today is a high-orbit satellite. Long March 3B is my country's first single model of launch vehicles to complete 100 launches, and has helped implement tasks such as lunar exploration and Beidou engineering.

According to reports, the Long March 3B carrier rocket will continue to maintain high-density launch this year and complete more than a dozen major space missions such as asteroid exploration.

The "Black Light Factory" keeps adapting to high-density launches day and night

This year, the Long March series of rockets will continue to maintain high-density launches, so the production of rockets must also keep up with the pace. At the "black light factory" of the China Launch Vehicle Technology Research Institute, key components such as the rocket's "steering wheel" are being accelerated.

The "black light factory" is also called a smart factory. It is named because the machines in the workshop are managed by artificial intelligence and can operate automatically without lighting.

Here, workers place pre-installed workpieces and pallets on the workstation without anyone having to follow the whole process. From the raw materials to the final product, most of the work is automatically completed by the machine, and the final product is like copying and pasting.

China Aerospace Science and Technology Corporation Zhang Hongchao: This equipment is now carrying out the self-replacement of the robot. It will place the processed parts on the workstation, and then take one part on the workbench of the machine tool. The positioning accuracy of the workbench of the machine tool can reach the micron level.

Zhang Hongchao introduced that as an indispensable device for rockets, servo mechanisms must ensure sufficient production capacity to meet the high-density launch needs of the Long March series launch vehicles. And in the entire China Launch Vehicle Technology Research Institute, there are many such intelligent "black light factories".

The development of Chang'e-7 is progressing smoothly

In 2024, Chang'e-6 completed the feat of human beings' first sampling and return on the back of the moon. This year, the development of Chang'e-7 and Chang'e-8 will also be steadily promoted during the fourth phase of the lunar exploration.

In the Deep Space Exploration Laboratory, scientific researchers are jointly developing the Chang'e-7 science payload in Beijing and Anhui. The creativity of this payload comes from elementary school students in Changsha. It will go to the south pole of the moon with the Chang'e-7 probe to try to use the interaction of electromagnetic fields to achieve the flag flying on the moon.

If the plan goes well, this will be the first flag that flutters on the moon's surface. Zhang Tianzhu, deputy director of the Future Technology Research Institute of Deep Space Exploration Laboratory, introduced that this method will help build young people's understanding and understanding of my country's aerospace industry, and stimulate their interest and enthusiasm in engaging in the aerospace industry in the future.

Chang'e-7 is scheduled to be launched in 2026 and will go to the South Pole of the Moon to find evidence of the existence of water ice. In addition, scientific researchers are currently promoting the demonstration work of subsequent Chang'e-8 and the International Lunar Research Station.

Zhang Tianzhu, Vice President of the Future Technology Research Institute of Deep Space Exploration Laboratory: Our goal is to build a sustainable and scalable comprehensive scientific experimental facility with long-term autonomous operation and short-term participation, and to build a basic model of the international lunar scientific research station around 2035.

The busy scene of China's commercial aerospace

In addition to the national team's mission, my country's commercial aerospace will also be very busy in 2025. At the beginning of the new year, commercial rockets and commercial satellite companies are already busy.

At the Blue Arrow Aerospace Rocket Manufacturing Base in Jiaxing, Zhejiang, developers are assembling and welding rocket cabins in the factory, which will be used for the Zhuque III, which is planned to implement its first flight this year.

The leader of the first group of the Blue Arrow Aerospace Jiaxing Rocket Manufacturing Base Installation and Welding Group Hu Shaoxiong: In 2025, everyone is full of energy, working overtime every day, and some workstations work in two shifts. In order to successfully complete the mission, I hope that the first flight of the Zhuque 3 in 2025 will be successful.

This year, my country's multi-type commercial liquid rocket will be for the first time, and constellations such as satellite Internet and commercial remote sensing will also be deployed on a large scale. At the Jiuquan Satellite Launch Center, the atmospheric detection remote sensing satellite developed by Galaxy Aerospace is under test and is scheduled to be launched in January this year.
