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.

二 | 此时节昼夜温差大，养生宜早睡早起、防寒保暖，饮食注重滋阴润燥，顺应季节变化。 “离离暑云散，袅袅凉风起。
三 | 池上秋又来，荷花半成子。” 今天（8月23日）10时18分 我们迎来“处暑”节气 制图：缪林西 “处”有“终止、躲藏”之意 处暑的到来 意味着暑热正式进入尾声 在这个时节 瓜果飘香，鱼鲜鸭肥 秋日的大美之色即将次第铺开 处暑·三候 一候鹰乃祭鸟 鹰自此日起感知秋之肃气，开始大量捕猎鸟类，但人们发现，鹰捕获猎物之后，不是马上就吃，而是将猎物堆积在巢穴附近，古人认为老鹰是在举行祭鸟的仪式。 二候天地始肃 处暑后，秋风萧索，大地在这股肃杀中变得更加庄严而清新。植物们褪去了往日生机勃勃的绿色，逐渐换上金黄的外衣。 南平武夷山。图源：陈美中 三候禾乃登 “禾”指的是各种稻谷，“登”就是成熟、收获的意思。处暑是水稻成熟的时候，我国南方大部分地区都处在收割中稻的农忙时节。
四 | 此外，一些夏秋作物也即将成熟。 处暑·习俗 在福建，民间有不少处暑传统习俗。 01出游赏秋 清风送爽，暑气渐消，正是一年中郊游的好光景。民间素有“七月八月看巧云”之说，此时的云朵疏朗轻盈，变幻万千。
五 | 趁温度恰宜、秋景初萌，约上亲友踏郊野、登高处，看天高云淡，闻稻香弥漫。 泉州清源山 泉州，是一座非常适合秋季来旅游的城市。暑热刚退，不燥不寒，一切都恰到好处。 清源山。
