China accelerates LEO satellite deployment with two launches in 12 days, but gap remains in launchpad efficiency, rocket reusability: expert_我的网站

A | 8 月 25 日消息,广汽集团董事长冯兴亚今日发布微博称,自己与团队昨日(8 月 24 日)赴深圳再次拜访华为创始人任正非,围绕启境下一阶段发展以及广汽与华为双方合作进行深入交流。

Two successful launches among China's recent frequent moves caught particular attention of space watchers - the 24th group of low-Earth orbit internet (LEO) satellites aboard a Long March-12 rocket was sent from a commercial spacecraft launch site in the southern island province of Hainan on Sunday, 12 days after the 23rd group of LEO satellites aboard a Long March-8A rocket was launched from the same Hainan site on August 4.
Sunday's mission marked the 663rd launch of the Long March series of carrier rockets, which on Monday sent an SEO satellite into preset orbit, per Xinhua.
Experts said the launches of two groups of LEO satellites within 12 days underlined that China is notably accelerating its pace of building its satellite internet constellation.
"The launch of LEO satellites has now entered a regular and cyclical rhythm, with batches of satellites continuously being sent into orbit at relatively stable intervals," Kang Guohua, a senior member of the Chinese Society of Astronautics and a professor of Aerospace Engineering at Nanjing University of Aeronautics and Astronautics, told the Global Times on Monday.
China launched the first group of LEO internet satellites on December 16, 2024, proceeding to the 24th batch in about 20 months. Kang said three major production and launch "assembly lines" are supporting the effort: satellite factories featuring centralized design in Beijing, coordinated supply chains and mass production; rockets with streamlined launch and testing procedures and multiple configurations; and launch sites capable of supporting routine constellation deployment.
The Long March-12, which played a key role in the latest LEO satellite launch, is China's first 4-meter-class single-core-stage carrier rocket and was specifically developed for commercial launch needs. It is about 62.6 meters long, has a liftoff mass of 430 tons and can carry more than 12 tons to low-Earth orbit. Its first stage is equipped with four 1,250-kilonewton pump-fed liquid oxygen-kerosene engines and uses a newly developed coal-based aerospace kerosene, according to Shanghai Academy of Spaceflight Technology.
The rocket adopts a "three-horizontal" launch preparation model: horizontal assembly, horizontal testing and horizontal transportation. Depending on mission requirements, it can use fairings with diameters of 4.2 or 5.2 meters and support both single-satellite and multi-satellite launches into different orbits.
"This flexibility makes the Long March-12 particularly suitable for the 'one rocket, multiple satellites' model required for constellation deployment, making it one of the main launch vehicles currently used for LEO constellation missions," Kang said.
The mission also highlighted the launch site's growing ability to support high-frequency launches. The rocket took only two and a half days from being transported to the launch area to liftoff, setting a record for the shortest time a rocket occupied the launch position at the site, Kang said.
Despite the rapid progress, experts cautioned that the 228 satellites currently in orbit remain some distance from the ultimate goal. China's satellite internet project has a long-term goal of deploying nearly 8,000 satellites and is now in an accelerated "weaving" phase.
China's advantage lies in its ability to control costs and boost production efficiency once satellite manufacturing reaches mass-production scale, another expert surnamed Liu told the Global Times.
"Whether it is the production capacity of AI centers or the factory in Hainan, which has an annual satellite manufacturing capacity of 1,000 units, satellite production itself is not the problem," Liu said. "More bottlenecks lie in the operational efficiency of launch pads and the rocket payload and recovery technology."
The real challenge lies in rocket reusability. Only by lowering launch costs and increasing launch frequency can China sustain a pace of more than one launch per week. This is also the strategic significance of accelerating the development of reusable rocket technology, including the Long March-10B and privately developed rockets, Kang further noted.
Chinese Academy of Engineering academician Deng Zhongliang previously said in an interview that satellite internet will serve as an indispensable space-time infrastructure for 6G, enabling emerging industries worth trillions of yuan, including the low-altitude economy, advanced autonomous driving and the Internet of Things (IoT).

。华为智能汽车解决方案 BU CEO 靳玉志随后发文,谈及了任正非与冯兴亚的再次会面。

B | 靳玉志重申:“华为坚持不造车,只把最好的智能技术、工程能力和体系经验,注入到车企的整车定义中去。”靳玉志强调,启境是华为智能汽车业务重要的战略级合作标杆,双方将持续携手探索“下一代智能汽车”。而根据规划,双方合作的首款阔五座 SUV 车型 —— 启境 GX7 计划在 9 月份上市。据此前报道,在 8 月 21 日的 2026 成都车展上,启境 GX7 实车迎来首秀。新车主打“空间智能百变”,首搭华为鸿蒙座舱 HarmonySpace 6、预埋 L3 级高阶架构,并采用 L3 级全链路八大冗余架构设计。
