Lixun-1 upper stage, a versatile "space tug" developed by China's commercial space firm CAS Space, is scheduled to make its maiden flight in the first quarter of 2027 after completing a series of key propulsion-system tests, the developer and its chief designer told the Global Times on Tuesday.
The "tug" is designed to ferry satellites from one orbit to another and support missions ranging from constellation deployment to lunar exploration. 
While the main stages of a rocket carry payloads from the ground into an initial orbit, an upper stage takes over once the craft is in space. By repeatedly restarting its engine and changing orbit, Lixun-1 can deliver satellites to higher or different orbits, distribute multiple spacecraft to separate destinations during a single launch, or send probes onto trajectories toward the moon and beyond, Global Times learned from the developer.
Yang Haoliang, chief designer of the Lixun-1 upper stage, compared the system to a shuttle service. "If the regular stages of a launch vehicle are like a long-distance bus," - they carry the upper stage and satellites from Earth to a near-Earth parking orbit - the upper stage then takes over as a "space tug," carrying its satellite "passengers" onward to their designated orbital "stops," Yang explained. 
That capability can have a direct impact on how efficiently satellites are launched and operated, Yang said. If a satellite has to climb from an initial orbit to its final destination using its own engine, the process can consume a considerable amount of onboard propellant and reduce the fuel available during its operational life. An upper stage can instead perform that orbital transfer, helping conserve satellite fuel and potentially extend its service life.
It can also make one rocket launch do more work. Instead of releasing a batch of satellites into roughly the same orbit, Lixun-1 can repeatedly ignite its engine and maneuver between deployments, sending different satellites to different altitudes and inclinations. Yang said this would help accelerate constellation deployment while improving the efficiency of individual launches.
The practical ambitions behind the system are backed by a major technical milestone reached this month. In August, Lixun-1 completed its PV-001 integrated propulsion-system coordination firing test, during which the entire system operated smoothly for 566 seconds.  
Yang told the Global Times that the current Lixun-1 upper stage has a thrust of 20 kilonewtons and can achieve a specific impulse of 315 seconds, which he described as reaching an internationally leading level. The August firing covered the planned profile for the maiden mission, an important step before the system proceeds to flight testing.
The test was more than a demonstration of the engine itself. As an important system-level verification during development, it examined the coordination and engineering reliability of the engine pressurization system, propellant delivery system, propellant management system and servo-control system under the fully integrated configuration.
Of a series of tests that accumulated 5,211 seconds of firing time, the latest one focused on three core technologies: a high-thrust, high-performance 20-kilonewton upper-stage engine capable of multiple starts; balanced propellant delivery from multiple parallel tanks; and a highly reliable integrated electrical system. Their successful verification means Lixun-1 has completed its system-level testing and is ready to move into the flight-test phase, according to the developer.
Lixun-1 has been designed as a modular and generally adaptable upper stage rather than a system tied to only one rocket. It is intended to work with CAS Space's Kinetica-2 and Kinetica-2 heavy-lift variants as well as other launch vehicles, Yang said.
When paired with the Kinetica-2 family, Lixun-1 could significantly expand the rocket's mission range. For communications missions, it could deliver satellites to geosynchronous transfer orbit or even directly to geosynchronous orbit, conserving satellite propellant while supporting the deployment of high-throughput satellites and future 6G communications spacecraft.
For multi-satellite missions, the combination could distribute spacecraft to different orbital altitudes and inclinations during a single launch, potentially serving both low-Earth-orbit constellations and medium- or high-orbit payloads. For deep-space missions, it could place probes onto Earth-moon transfer trajectories and support lunar exploration, Yang said.
The upper stage is designed to be able to conduct more than 20 engine ignitions, autonomously plan orbital-transfer routes and operate under the vacuum and extreme temperature conditions of space. After completing payload deployment, it can also carry out orbital disposal maneuvers to reduce space-debris risks.
Yang said the Lixun-1 and Kinetica-2 combination is designed to cover the vast majority of commercial satellite launch requirements while retaining the ability to participate in major national space projects. More broadly, the upper stage forms part of CAS Space's effort to build launch capabilities reaching medium and high Earth orbits and deep space, extending the reach of China's commercial space sector toward higher orbits and more distant destinations.
。8月14日，一场名为“法典护古树 法治润枣乡”《生态环境法典》实施宣传活动，在淳安县左口乡显后村百年古枣林及村新时代文明实践站举行。左口乡拥有5000余亩连片古枣林，其中树龄超300年的古枣树达600余株，显后村更是有着800余年护绿文脉。自南宋嘉定年间建村，当地方氏先祖便秉持“山林固水土、山水养村庄”的朴素生态观，划定村南朝山为宗族禁山，立下“只许养护、严禁砍伐”的祖训规约。世代村民严守古训，禁止随意伐树、进山狩猎，依靠村规涵养水土、抵御山洪，为整片古枣林留存筑牢深厚群众根基。

二 | 如今，这份传承千年的生态智慧，正通过制度化、法治化方式延续传承。活动现场，工作人员为树龄412年的“江南枣树王”悬挂专属保护铭牌。一块小小的古树身份牌，清晰界定古树管护权责，成为具象化的法治保护凭证。同步揭牌成立古枣林公益诉讼联络点，依托林间实景开设特色“微课堂”，检察、司法工作人员现场解读古树名木保护相关禁止性条款、日常管护标准及破坏林木对应的法律后果，公开生态违法线索举报渠道，让生态法律知识走出文件、走进田间林间。淳安县人民检察院副检察长余爱华介绍，《生态环境法典》首次在立法层面确立生态环境检察相关制度，赋予检察机关更厚重的生态保护司法职责。古树名木属于不可再生的生态文化资源，损毁古树本质上侵害社会公共生态利益，检察公益诉讼正是古树保护的司法盾牌，能够实现“办理一案、警示一片、治理一域”的治理成效。本次活动同步发布两项长效管护举措：一是在显后村新时代文明实践站首发《生态环境法典（古树名木保护）》普法动漫短视频，把晦涩的法律条文转化为通俗动画，方便村民理解传播；二是林业部门正式发布左口乡古树名木保护名录，建立“一树一档”精细化管护台账，压实行业、属地、网格员三方管护责任，实现古树名木常态化规范化管护。检察机关结合本地古树损毁、林地破坏真实案例以案释法，细致讲解公益诉讼、生态修复、行政处罚等法律要点，清晰告知群众破坏古林的法律代价。左口乡乡长陈显锋表示，多部门联合林间普法，是淳安探索古树常态化保护、打造乡村生态法治样板的实践尝试。当地将持续压实属地管护责任，依托网格员包保体系，把古枣林生态保护融入乡村发展全过程，让百年古树在法治护航下永续生长。
