A rocket that once would have been discarded after completing its mission has now taken a different path - returning from the edge of space back to Earth. In the early hours on Wednesday, the Zhuque-3 Y2 reusable launch vehicle lifted off for a flight test, carrying not only a satellite payload but also a major test of China's emerging reusable rocket capabilities. After completing its orbital mission, the rocket's first stage attempted a controlled return and recovery, with its developers Beijing-based private firm LandSpace describing the mission as a key transition from technology verification toward engineering application for China's commercial aerospace industry.
About 137 seconds after liftoff, the rocket’s first and second stages separated. The second stage continued its flight and successfully placed the Honghu-03 satellite, independently developed by Hongqing Technology, into its designated orbit. And at around 7:43 am, the rocket’s first stage successfully made a soft landing as planned at the Zhuque-3 landing site in Minqin county, Northwest China’s Gansu Province, marking the successful completion of the flight test mission.
This mission marked China's first-ever recovery of a launch vehicle's first stage using landing legs, as well as the country's first land-based recovery of the first stage of an orbital-class launch vehicle, the developer highlighted.
The achievement came shortly after China's Long March-10B reusable rocket successfully completed its maiden flight and a sea-based recovery test on July 10, marking a wave of breakthroughs in reusable launch technology. The parallel progress of state-owned and private aerospace players through different technical approaches is creating a dual-track development landscape for China's future low-cost and high-frequency space transportation, some aerospace experts told the Global Times.

Unlike traditional expendable rockets, which are discarded after a single mission, reusable launch vehicles are designed around an entirely different concept: a rocket should not only complete a launch, but also return safely and be prepared for future missions.
According to LandSpace, for conventional expendable liquid launch vehicles, the rocket itself represents the majority of launch costs, while fuel expenses generally account for only 1-3 percent. The first stage typically makes up about 70 percent of the total rocket cost. As a result, repeated reuse of rockets - particularly the first stage - can significantly lower launch costs by amortizing the cost of the vehicle over multiple missions. For partially reusable rockets that reuse the first stage while discarding the second stage, the cost advantage becomes increasingly evident as the number of reuse cycles grows.
The Zhuque-3 is a reusable liquid oxygen-methane launch vehicle independently developed by Beijing-based private aerospace firm LandSpace for future large satellite constellation deployment missions, according to the company's statement.
The rocket adopts a two-stage configuration, with a diameter of 4.5 meters, a total length of 66.1 meters and a liftoff mass of about 570 tons. Its first stage is equipped with nine Tianque-12A liquid oxygen-methane engines, as well as recovery systems including grid fins, attitude control systems and landing legs, enabling autonomous return and soft landing after orbital missions, LandSpace said.  
The Y2 mission was conducted on the basis of experience accumulated from the previous flight test, with improvements focused on recovery reliability, flight control and engine performance.
LandSpace said it optimized the first-stage landing propulsion scheme by reducing the number of engines used during landing ignition, simplifying system design and improving reliability during the recovery phase. The company also added an autonomous safety control function capable of predicting landing points based on flight conditions and making corresponding safety adjustments.  
The mission also further verified key technologies including the use of stainless-steel rocket structures, liquid oxygen-methane propulsion and landing-leg recovery systems.
According to LandSpace, stainless steel provides advantages in manufacturing cost, processing efficiency, high- and low-temperature performance and post-recovery maintenance, making it suitable for reusable rocket development.

The significance of Zhuque-3 Y2 extends beyond one flight test, as it reflects China's broader effort to develop reusable launch systems through multiple technological routes, according to Chinese experts.
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 that China has become the second country after the US to develop orbital-class rocket recovery capabilities.
The US currently leads reusable rocket development, with SpaceX and Blue Origin advancing different recovery technologies. China, meanwhile, has seen both state-owned aerospace programs and private companies explore different technical pathways, creating a diversified development pattern, Kang said.  
According to Kang, the parallel development of different approaches demonstrates the advantages of combining national strategic capabilities with market-driven innovation.  
Pang Zhihao, a prominent Chinese space exploration expert and retired researcher from the China Academy of Spacecraft Technology, told the Global Times that the successful recovery of Zhuque-3 would carry special significance for China's private aerospace sector.
A landing-leg recovery approach would mean that private aerospace companies have completed the full process of developing a large-capacity reusable rocket system, validating key technologies including stainless-steel structures, multi-engine propulsion and recovery systems, Pang said.  
More to expect 
LandSpace said the first stage represents a significant share of the total cost of a liquid launch vehicle. Through repeated reuse, the cost of each launch can be gradually reduced, while production cycles can be shortened and launch frequency increased.  
Such capabilities are becoming increasingly important as countries and companies accelerate the deployment of large low Earth orbit satellite constellations, it added.
The Zhuque-3 has demonstrated the ability to support various commercial missions, including satellite constellation deployment, single satellite launches and rideshare missions, according to LandSpace.
The company said the rocket has achieved a maximum orbital payload capacity of 14.2 tons in expendable mode, while its reusable configuration is designed to support future constellation deployment needs.  
The Y2 mission also carried the Honghu-03 satellite developed by Hongqing Technology, combining reusable technology verification with a commercial launch application scenario. LandSpace said the mission verified the full chain of "design, manufacturing, testing, launch and recovery," laying the foundation for future commercial operations.  
The Zhuque-3 Y2 test comes as China's aerospace industry accelerates efforts to develop reusable launch vehicles.
According to Chinese experts, multiple companies are now exploring different recovery technologies, including vertical landing and other innovative approaches, reflecting the rapid growth of China's commercial aerospace ecosystem.  
Reusable liquid launch vehicle, Pallas-1 will begin its mission from Galactic Energy's independently built facility at the Dongfeng Commercial Aerospace Innovation Test Zone in northwestern China, where the company will soon complete testing, propellant filling and launch preparation operations, according to its developer Galactic Energy on Thursday.
Orienspace's Gravity-2 reusable large liquid launch vehicle is undergoing final ground testing ahead of its maiden flight, which is scheduled in the fourth quarter of 2026. The rocket is designed with a low Earth orbit payload capacity of 21.5 tons.
Space Pioneer is advancing verification and joint testing of its Yuanxingzhe-1 (YXZ-1) rocket, while i-Space's Hyperbola-3 reusable rocket has completed full-cycle ground verification of offshore recovery and landing technologies and is expected to conduct its maiden flight around the end of 2026.
Meanwhile, CAS Space's reusable Lihong-2 vehicle is being developed as a platform for verifying key recovery and reuse technologies, as well as conducting microgravity experiments. The vehicle is scheduled to complete its maiden flight and 100-kilometer-class recovery verification test in 2026.
Pang said reusable rocket technology could help lower launch costs, increase mission frequency and provide stronger support for emerging sectors such as satellite internet, space-based information networks and future large-scale space applications.  
For China's private space sector, the Zhuque-3 Y2 mission represents a transition from technology verification toward engineering application, according to LandSpace. The company said it aims to further build a "launch-recovery-inspection-reuse" cycle to support future high-frequency and low-cost commercial operations. 
Experts said reusable rocket technology could help reduce launch costs, increase launch frequency and provide stronger support for emerging sectors such as satellite internet and large-scale space applications.  
The future challenge for China's reusable rocket developers will be turning successful flight tests into repeatable commercial operations, as the country advances toward a new era of high-frequency space transportation, they noted.

B |     全球化日益加深和国际局势瞬息万变的今天,中美关系的走向无疑是关注的焦点之一。就在8月25日,第三届中美1.5轨对话拉开帷幕,成为解析两国关系的一扇窗。

C | 各方代表齐聚一堂,私下交流,试图通过不那么正式的方式探讨彼此关心的敏感议题,从而为未来的高层接触奠定基础。    这种“1.5轨”的对话模式独具魅力,既能避免两国政府在正式场合下可能面临的政治压力,又能让各界人士畅所欲言。在这一氛围中,双方讨论了包括政治互信、经贸合作以及科技领域的合作等重要议题,而这些恰好是近年来中美关系中的“痛点”。    特别是在特朗普执政以来,中美之间的摩擦愈发频繁,尤其是在经济和技术领域的竞争上,双方都希望通过这样的对话来寻找突破口。        然而,值得注意的是,在这次对话举行的同时,美国却在全球范围内悄然加大了对伊朗的经济制裁力度,仿佛整个世界都在经历一个巨大的转折。这种制裁的扩大不仅仅局限于伊朗本土,也将直接影响到与伊朗有贸易往来的国家和企业,特别是中国,这无疑给中美关系投下了一层阴影。    美国财政部在24日发布的公告中,宣布从即日起扩大对伊朗的制裁范围,涵盖航空、数字资产、黄金、航运和技术等多个领域。这一系列措施显示出美国切断伊朗经济来源的决心,意在将德黑兰推向绝境,从而迫使其在某些外交或军事问题上妥协。    特朗普政府的这种“经济战”做法,其实也是对其军事行动未达预期的一种补救。毕竟,显著效果的经济制裁能够更快地影响对手的生存环境。        我们不妨细想一下,美方如此强硬的做法会带来怎样的国际反响。首先,特朗普政府所采取的“二级制裁”策略,实际上就是要逼迫所有与伊朗有往来的国家在伊朗和美元体系中二选一。显然这是对全球经济的一种强制性干预。在这样的情况下,许多国家面临着被剔除出美元体系的风险,无形中增加了他们选择的难度。    然后,我们回过头来看中国。作为伊朗石油的主要买家,中国所承担的压力无疑是最大的。

D | 有数据表明,中国已经购买了伊朗海运石油出口的80%以上,若伊朗的能源渠道被彻底封锁,无疑将对中伊之间的合作带来巨大的冲击。    美国虽已对部分中国实体施加制裁,但其并未采取更加极端的措施,看来耀武扬威的同时也不得不考虑中国的特殊地位。若把矛头指向中国,可能引发的连锁反应将使得美国在全球经济中陷入更深的困境。        在这种复杂的背景下,中美双方都明白,保持沟通至关重要。正因如此,中美1.5轨对话的出现就显得尤为关键。

E | 它不仅是为了增进了解,更是为了在潜在冲突中找到和解的空间。两国正在努力将双边关系拉回可控的轨道,既是为了自身的利益,也是为了全球经济的稳定。    面对复杂多变的国际局势,中美双方都希望通过对话与沟通来降低误判风险。在这种背景下,谁都不希望因为误解而导致不可挽回的损失。但问题在于,当对话的内容变得尖锐、敏感,甚至必然会触及一些不想触及的话题时,如何处理这种复杂性,将是未来中美关系能否顺利推进的关键所在。

F |     中美关系正处在一个关键节点。在收紧经济制裁的背景下,双方的对话显得尤为重要。

G | 只有通过这样的形式,才能有效地减少误解和摩擦,为未来的交往铺平道路。然而,能否在波谲云诡的国际环境中寻找到兼容并蓄的发展策略,仍需双方的智慧与坚持。    未来的日子里,中美关系的走向将与全球经济的变化密切相关。我们期待看到双方在合作与沟通中不断前行,为世界的稳定与繁荣做出更大贡献。只希望,在这一波全球动荡、局势复杂的浪潮中,两国能够把握住机遇,化解潜在的危机,共同迎接一个更加美好的明天。返回,查看更多
