China, People’s Republic of China my country’s new generation of cargo spacecraft has been unveiled. It weighs about 5 tons, has low cost, high reliability and strong intelligence, and will make its maiden flight this year
In the exploration of the vast universe, China’s space industry has always made steady progress and continued to write new glorious chapters. As the key support for the construction and operation of China’s space station, cargo spacecraft plays a vital role in ensuring the supply of space station materials and the transportation of scientific research equipment. At present, China’s Tianzhou cargo spacecraft in service has made great contributions to the construction and maintenance of the space station with its excellent performance and reliable operation.
The Tianzhou cargo spacecraft is an advanced cargo spacecraft independently developed by my country. Since it was put into use, it has successfully carried out space station cargo transportation missions many times. It has a large carrying capacity and can deliver a large amount of living supplies, experimental equipment, propellants and other key materials to the space station, effectively ensuring the smooth development of astronauts’ on-orbit life and scientific research.
The Tianzhou cargo spacecraft is designed with full consideration of the needs of the space station. It has precise docking technology and efficient material unloading capabilities, and can achieve seamless docking with the space station, ensuring that materials can be quickly and accurately transferred to the space station. At the same time, the Tianzhou cargo spacecraft also has the ability to replenish propellant on orbit, providing important power support for the orbit maintenance and attitude adjustment of the space station, greatly extending the on-orbit operation life of the space station.
However, with the continuous advancement of China’s space station construction and the gradual implementation of future deep space exploration missions, higher requirements are placed on the performance and functions of cargo spacecraft. Against this background, my country’s new generation of space “couriers” – the Qingzhou cargo spacecraft came into being. At the 2025 “China Space Day” science exhibition, the Qingzhou cargo spacecraft was officially unveiled, attracting the attention of the global aerospace community.
The Qingzhou cargo spacecraft was developed by the Microsatellite Innovation Institute of the Chinese Academy of Sciences. It is a light, small and fast spacecraft that integrates “low cost, high reliability, high adaptability and high intelligence”. It is also an important part of the space-to-earth cargo transportation system of the Chinese space station. It has the characteristics of moderate capacity, fast and flexible, and outstanding benefits. It will further enhance the safety and reliability of the space station’s material supply, especially the heterogeneous backup capability, and provide a solid guarantee for the safe and stable operation of the Chinese space station in orbit.
The Qingzhou cargo spacecraft has a “small body” but contains “big energy”. According to Chang Liang, chief designer of the Qingzhou cargo spacecraft and researcher at the Microsatellite Innovation Institute of the Chinese Academy of Sciences, the Qingzhou cargo spacecraft weighs about 5 tons, has an upward transport capacity of more than 1.8 tons, and a downward transport capacity of 2 tons.
Such a capacity configuration can not only meet the daily material supply needs of the space station, but also adapt to the transportation tasks of different types of goods. Its loading volume is about 9 cubic meters, and the volume of the cargo compartment is 27 cubic meters, which can carry astronauts’ living supplies, scientific experimental equipment, scientific payloads, etc. The cabin adopts a four-layer shelf mode with a total of 40 cargo grids. For special cargo needs, corresponding interfaces are reserved on the shelves, which can provide suitable storage space for goods of different specifications and shapes, greatly improving the flexibility and efficiency of cargo transportation.
In order to further reduce the cost of cargo transportation to China’s space station and improve transportation efficiency, the Microsatellite Innovation Institute of the Chinese Academy of Sciences and the rocket developer China Science and Technology Aerospace jointly carried out a joint demonstration of ship-rocket integration. Integrated work was carried out in terms of structural design, test and launch process, measurement and control communication, and pre-launch loading plan. In response to the requirements of cold chain transportation of spacecraft, the launch process was optimized, and the ship-rocket integrated test was adopted to simplify the test and launch process. This integrated design concept not only improves the economy of the mission, but also greatly shortens the launch preparation time, enabling the Qingzhou cargo spacecraft to respond more quickly to the material needs of the space station and achieve rapid launch.
Shu Rong, commander-in-chief of the Qingzhou cargo spacecraft and secretary of the Party Committee of the Microsatellite Innovation Institute of the Chinese Academy of Sciences, said that the integrated single-cabin configuration design is a prominent feature of the Qingzhou cargo spacecraft. On the premise of meeting the mission requirements, the integrated single-cabin configuration can improve space utilization and improve the economy of the mission. The integrated configuration greatly reduces the size of the Qingzhou, providing the largest and best space for cargo, and providing astronauts with convenient and fast operating space. At the same time, this configuration makes it easier to choose the right carrier, can adapt to multiple types of rockets, meet the needs of rapid launch, and further enhance the flexibility and adaptability of the Qingzhou cargo spacecraft.
Intelligence is also a highlight of the Qingzhou cargo spacecraft. Qingzhou is equipped with an intelligent cargo transportation management system that can realize intelligent identification, positioning and management of cargo. Astronauts can quickly find the required items through voice interaction and other methods, which improves the efficiency of cargo delivery, reduces the workload of astronauts, and also reduces the risks caused by manual operation errors. This intelligent design concept not only reflects the innovative development of China’s aerospace technology, but also provides a useful exploration for the intelligent operation and management of future space stations.
In addition to its powerful cargo transportation capabilities, the Qingzhou cargo spacecraft also demonstrates diverse application potential. It can not only transport conventional cargo such as astronauts’ daily necessities and scientific experimental equipment, but also carry various test payloads, support manned or unmanned space science payloads and various on-orbit experiments, meet the diverse needs of the space station, and improve the scientific research and application value of the space station.
It is worth mentioning that the Qingzhou cargo spacecraft has also actively introduced the concepts and technical means of commercial aerospace. For the first time, the business model of cargo transportation system overall management is adopted to combine the carrier and the spacecraft more closely, so as to achieve the overall optimization design of the system; the concept of commercial aerospace is introduced to promote the rapid iteration and application of new ideas, new devices and new materials in the aerospace field, and form good economic and social benefits. In addition, the Qingzhou cargo spacecraft also plans to explore various business models such as naming rights, carrying IP culture, brand communication, and popular science cooperation, and carry out innovative cooperation with all walks of life in the society to form good economic and social benefits and promote the sustainable development of China’s aerospace industry.
This year, the first prototype of the Qingzhou cargo spacecraft is scheduled to fly for the first time, and the first prototype is scheduled to be ready for delivery next year, ready to carry out cargo transportation missions to the space station. With the gradual commissioning of the Qingzhou cargo spacecraft, the material transportation capacity of the Chinese space station will be further enhanced, providing a more powerful guarantee for the long-term stable operation of the space station and the implementation of deep space exploration missions. It is believed that in the near future, the Qingzhou cargo spacecraft will be like a smart “space ark”, shuttling back and forth in the vast universe, opening up a broader world for the development of China’s aerospace industry.
