Qingzhou, China's next-generation cargo spacecraft designed for future in-orbit supply deliveries, including missions to China's Tiangong Space Station, took center stage in Shanghai on Thursday as it made its first public debut.
The unveiling of the spacecraft's life-size model at the ongoing aerospace science exhibition at the Shanghai World Expo Exhibition & Convention Center, serves as part of the celebrations of this year's Space Day of China.
Developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences, Qingzhou is poised to embark on its maiden flight later this year. The development team is currently focused on finalizing the design of the spacecraft and software for the initial test phase. Production is also already underway for the subsystems and components of the test spacecraft, as confirmed by Chang Liang, the spacecraft's chief designer.

Literally meaning "Light Ship" in Chinese, Qingzhou features an integrated single-capsule configuration with a cargo volume of 27 cubic meters and a capacity up to 2 tons. It is designed to transport taikonauts' living supplies, scientific experiment equipment, and various scientific payloads.
It features a four-tier shelving system with 40 compartments and interfaces for special cargo needs, ensuring it can meet various demands during missions.
Notably, it can accommodate up to 300 liters for cold-chain transportation, ensuring that taikonauts have access to fresh produce during their space missions.
"Qingzhou is a swift and nimble spacecraft, following a design which is taikonaut-centered, of low-cost, high-reliability, high-flexibility and high-intelligence," said Shu Rong, commander of the Qingzhou project.
The cargo spacecraft incorporates intelligent payload schemes and designs to optimize cargo delivery, retrieval, and handling processes for astronauts, he said.
In addition to servicing the Tiangong Space Station, Qingzhou aims to offer commercial cargo services in the future, with a focus on generating economic and social benefits, Shu added.
Chang emphasized that Qingzhou embraces commercial spaceflight concepts and technical approaches, highlighting the spacecraft's cost-effectiveness achieved through technological innovations and streamlined launch procedures.
At the design stage, Chang said, the development team studied cargo spacecraft, both domestic and international, including the US Dragon spacecraft, Europe's ATV, Japan's HTV and China's Tianzhou series. Ultimately, based on the spatial requirements issued by the China Manned Space Agency, they independently designed and developed the compact, integrated Qingzhou cargo spacecraft.
"We've opted for an integrated single-capsule design for greater flexibility in launch vehicle selection, making it compatible with multiple rocket types and supporting rapid launch needs," Chang said.

For its maiden flight, Qingzhou will aboard Lijian-2, a reusable rocket developed by CAS Space, a commercial spaceflight company under the Chinese Academy of Sciences.
China's commercial aerospace sector saw rapid development in 2024, with Qingzhou cargo spacecraft selected as one of the two winners in the China Manned Space Agency's solicitation for a low-cost cargo transportation system. The Haoloong space shuttle, a reusable cargo spaceplane designed by the Chengdu Aircraft Design and Research Institute in Sichuan province, was the other winner.
"Qingzhou represents a milestone in the commercial development of China's manned space program," Chang said. "The flexibility of commercial aerospace, its cost control, and pursuit of innovation are inherent advantages that will effectively strengthen China's overall space capabilities."
