On the 15th, the light boat test spacecraft (White Elephant) independently developed by the Institute of Micro Satellite Innovation of the Chinese Academy of Sciences released the first batch of scientific and engineering test results. Since operating in orbit for half a month, the spacecraft has successfully achieved its established goals of key technology verification, low-cost design and exploration, and expansion tasks, laying the foundation for the subsequent prototype development of light cargo spacecraft. At present, the light boat experimental spacecraft has completed flight control testing, actively lifted to a 600 kilometer orbit, and entered the long-term operation phase. The Qingzhou experimental spacecraft was launched on March 30th, with a total weight of 4.2 tons and carrying a 1-ton scientific experimental payload. It has a 3-year orbital flight capability. "The spacecraft has achieved a number of breakthroughs in key technologies of the platform, applied many new technologies and processes in the sealing section, propulsion system, thermal control and environmental control system, and successfully carried out core tests such as autonomous approach and safe evacuation of large inertia spacecraft, and verification of long-term residence capability," said Chang Liang, director of the Micro/Nano Satellite Overall Research Institute of the Chinese Academy of Sciences and chief designer of the light boat cargo spacecraft. Low cost technology is a major highlight of the light boat experimental spacecraft. The foldable ultra-thin flexible monocrystalline silicon solar cells used in spacecraft perform stably in orbit, with a cost only one tenth of traditional cells; The new system's air-to-air communication module has excellent performance and can achieve data transmission over 450 kilometers; The application of 3D printing technology and new materials has effectively shortened the manufacturing cycle. At the same time, the spacecraft successfully completed multiple expansion tasks, released two small satellites, and conducted long-distance approach and evacuation tests with the New Voyage 01 satellite, successfully verifying the multi-body attitude and orbit coupling control technology. Chang Liang stated that this test flight not only provided key data support for the prototype development of cargo spacecraft, but also explored a low-cost and commercialized new path for space operations. In the future, the Qingzhou cargo spacecraft will continue to iterate and assist in the high-quality development of China's commercial aerospace industry. (New Society)
