The reporter recently learned from China Aerospace Science and Technology Group Co., Ltd. that in order to meet the needs of the commercial aerospace market, China is urgently developing reusable rockets in the 4-meter and 5-meter scales, with plans to make their first flights in 2025 and 2026, respectively. "Reusable rockets are one of the important development directions of future space exploration. They are characterized by low cost, high efficiency, high technical difficulty and more environmental protection. To achieve this goal, many technical problems need to be overcome, and new materials, structures and control methods need to be explored and tackled. The development of 4m and 5m reusable rockets means that we have made a further step in the commercial space launch market." CAS Member Wang Wei, Minister of Research and Development Department of China Aerospace Science and Technology Group, said. China's commercial aerospace industry is entering a stage of rapid development. The recently released Blue Book of China's Aerospace Science and Technology Activities (2023) shows that China completed a total of 26 commercial launches in 2023, with a success rate of 96%; A total of 120 commercial satellites were developed and launched, accounting for 54% of the total number of satellites developed and launched throughout the year. At the same time, the construction of launch and measurement and control facilities continues to advance. The first launch station of Hainan International Commercial Space Launch Site has been officially completed, and the second station is accelerating its construction. Both stations will have the ability to perform 16 launch missions per year. This year, commercial aerospace has been included in the government work report, injecting more confidence into the industry's development. Wang Wei stated that we should fully mobilize high-quality social resources, share development opportunities, actively serve national strategies, jointly form a cooperative and win-win industrial ecosystem, accelerate breakthroughs in key technologies of high cost-effective commercial satellites, launch communication, navigation, remote sensing and comprehensive commercial satellite products, develop high cost-effective rocket engines urgently needed in the commercial market, and cultivate and develop commercial aerospace into new productive forces, Promote the comprehensive development of China's aerospace industry.
