人民日报：商业航天，“高热度”下的“冷思考”

Core Viewpoint - The development of China's commercial space industry is at a critical juncture, with significant opportunities and challenges ahead, particularly in achieving reusable rocket technology and enhancing launch frequency and cost-effectiveness [1][6]. Group 1: Industry Development and Opportunities - China has submitted plans for a satellite network comprising over 200,000 satellites, necessitating rapid advancements in rocket capacity, satellite production, and reusable technology [1]. - By 2025, China aims to conduct 25 commercial rocket launches and place 311 satellites into orbit, representing 84% of the total satellites launched that year [1]. - The industry is witnessing a surge in demand for rocket launches driven by extensive satellite deployment, with a need to launch over 25,000 satellites in the next nine years [3]. Group 2: Technological Innovations - Blue Arrow Aerospace's Zhuque-2 rocket became the world's first liquid oxygen-methane rocket to reach orbit, marking a significant step towards reusable rocket technology [2]. - Companies like Tianbing Technology and Galaxy Aerospace are pioneering various technologies, including "one rocket, 36 satellites" launch capabilities and lightweight engines [2]. - The development of stackable satellites is emerging as a trend to enhance launch efficiency, allowing multiple satellites to be launched simultaneously [5]. Group 3: Efficiency and Production - The industry consensus is to produce satellites in bulk, akin to automobile manufacturing, to improve efficiency [4]. - Galaxy Aerospace's recent satellite launch demonstrated a fully digitalized production process, significantly reducing assembly time from several months to as little as 20-25 days [4]. - The Chinese aerospace industry is advancing towards a model where 500 kg satellites can be ready for launch in just 20 days [4]. Group 4: Challenges and Constraints - The commercial space sector faces challenges in establishing a profitable business model, with many companies still reliant on external funding and struggling to generate revenue [6]. - Limited launch opportunities due to a shortage of launch sites and resources are constraining the frequency of commercial launches [9]. - The high cost of rocket launches, primarily driven by engine and airframe expenses, remains a significant barrier to industry growth [7][8]. Group 5: Policy and Support - The Chinese government is actively promoting the commercial space sector, with policies aimed at fostering innovation and reducing regulatory burdens [14]. - The State Council has issued guidelines to encourage the expansion of satellite service applications, aiming to bridge the gap between satellite capabilities and market demand [12]. - There is a call for a regulatory framework that supports frequent launches and efficient resource allocation, akin to aviation management practices [10].
