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.
