At 18:21 on August 4, 2025, China successfully launched the Long March 12 carrier rocket at the Hainan Commercial Space Launch Site, successfully putting the 07 sets of satellites in the low orbit of the satellite Internet into the scheduled orbit. The launch marks an important breakthrough in the field of satellite Internet for China Aerospace.

The Long March 12 carrier rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation and is China's first 4-meter single core stage carrier rocket. This rocket has a powerful carrying capacity, with a carrying capacity of no less than 12 tons in low Earth orbit and no less than 6 tons in a 700 kilometer sun synchronous orbit. This launch adopts a one rocket, multi satellite wall mounted launch mode, and through multiple technological innovations, including the use of composite material multi satellite adapters, digital simulation docking, and satellite rocket docking tests, ensures the efficiency and safety of satellite layout.

It is worth noting that the 07 sets of satellites of the Internet LEO launched this time were all developed by Galaxy Aerospace, which is the first time that a private commercial aerospace company has developed such satellites in batch. The development of the satellite adopts a modular design for mass production, supporting parallel assembly, integration, and testing of multiple modules. Combined with robot cabin assembly technology, batch parallel testing has been achieved. These satellites are manufactured at the Galaxy Aerospace Satellite Smart Factory, which extensively utilizes intelligent assembly robots and digital manufacturing systems, enhancing the flexible production and digital manufacturing capabilities of the production line. The satellite development cycle has been shortened by 80%, and the factory has the ability to produce over 100 1000 kilogram satellites annually.
