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).

四 | 拳击/格斗的不可能三角：体型、爆发力、持久——想要体型优势，就得脱水降重，于是不能持久；想兼具持久和爆发力，就不能减重，于是没体型优势。

五 | 足球的不可能三角：高位逼抢、高压续航、集体健康——高逼抢累人，高续航+高逼抢=过载于是受伤；所以跑动强队没几支能持久；巴黎过去两年的欧冠，也托赖了法甲强度低：甚至可以替补踢法甲、主力踢欧冠。跑步的不可能三角：跑量、强度、健康——跑量堆心肺，强度堆配速，跑量X强度毁健康。所以三个里面一般只有俩。将上面这些道理合起来，就是竞技世界终极不可能：极端产量 × 团队完整 × 最终冠军。具体有：NBA常规赛得分王不夺冠——三分球时代只有：2000鲨鱼、2025亚历山大，以及乔丹的六个冠军。

六 | NBA常规赛助攻王不夺冠——三分球时代只有：1987魔术师，2020勒布朗。NFL传球码数王不夺超级碗——例外只有2022年马霍姆斯。那年他也是NFL本世纪唯一常规赛MVP+超级碗MVP。世界杯金靴奖不夺冠——1986年以来，只有2002的罗纳尔多例外。道理也不难明白：世界杯金靴：球队就指望你进球。NBA常规赛得分王：球队就指望你得分。NBA常规赛助攻王：球队就指望你传球——1987魔术师和2020勒布朗自己还能得分，且1987湖人还有个天勾，2020湖人还有个浓眉。NFL传球码数王：球队就指望你传球。要么是球队太弱，要么是你独掌球权，要么是两者兼具。

七 | 总之你一个人厉害，那对手只要关注你就好咯！马霍姆斯六个全明星赛，三个超级碗：其中传球码数最少的2019和2023各一个超级碗。汤姆·布雷迪七个超级碗，常规赛传球码数分别是生涯倒一、倒三、倒四、倒五、倒九、倒十二，最好的2020是生涯第七。2002罗纳尔多则是另一个例子：1998年他4球3助攻，基本包揽巴西进攻发起，金球奖但世界亚军；2002他专注禁区进球，里瓦尔多和小罗帮他创造，于是他银球奖但世界冠军。个人承担少一点，结果反而好一点。但乔丹终究做到了六次得分王x总冠军？乔丹1987-1990，场均37分5助攻、35分6助攻、33分8助攻、34分6助攻。1991-93：场均32分6助攻，30分6助攻，33分6助攻，球队61、67、57胜，三连冠。1996-98：场均30分4助攻，30分4助攻，29分4助攻，球队72、69、62胜，三连冠。72胜、69胜和67胜的年份，他场均30分4助攻、29分4助攻、30分6助攻：战绩最好的年份，反而是数据比较差的年份——因为球队不用他自己扛，他也把任务更多分给队友们了。自己更多无球，更多做些数据看不见的事。所以哪怕是乔丹这样的反规律存在，六次得分王x总冠军，依然是常规赛数据相对不算壮丽的年份。只是他得分能力超越时代太多，所以才能得分王x总冠军手拿把掐。乔丹不是在夺冠时变得更会得分，而是在夺冠时不用那么拼命得分。
