SpaceX宣布：降轨！此前曾危险抵近中国空间站

Core Viewpoint - SpaceX's Starlink plans to lower the orbits of approximately 4,400 satellites by 2026 to enhance space safety, marking the largest satellite deorbiting operation in the company's history [1][2] Group 1: Starlink's Actions and Impacts - In 2026, Starlink will lower its satellites from approximately 550 kilometers (342 miles) to about 480 kilometers (298 miles) to reduce collision risks and facilitate quicker deorbiting in case of satellite anomalies [2][8] - A recent incident involved a Starlink satellite experiencing an anomaly, resulting in a rapid descent of 4,000 meters and the creation of debris, which poses risks to other operational satellites [2][8] - Starlink has become a dominant force in the U.S. commercial satellite constellation expansion, with over 10,000 satellites in orbit and achieving 167 orbital launches in 2025, accounting for 85% of the total U.S. launches that year [2][8] Group 2: Global Commercial Space Industry Trends - The global commercial space industry is entering a "golden age," driven by low Earth orbit satellite internet like Starlink, characterized by technological integration and collaborative innovation across the entire industry chain [4][9] - As of December 2025, there have been 325 space launches globally, with 4,026 satellites placed into orbit, including 87 launches from China, highlighting the significant role of private enterprises in the commercial space sector [4][9] - SpaceX's Falcon 9 rocket leads in launch frequency and payload capacity, while China's space industry is steadily advancing to close the gap with international leaders, supported by emerging private companies [4][9] Group 3: Future Prospects for China's Commercial Space Industry - In the next 1 to 2 years, China's commercial space sector is expected to experience accelerated technological breakthroughs and market expansion, with advancements in reusable rocket technology and satellite mass production [5][10] - The commercial space market's growth will benefit upstream satellite manufacturing and core components, while downstream application services are anticipated to become the largest value pool [5][10] - Increased international competition is expected, with China and the U.S. likely to develop a "parallel running" dynamic, where China may lead in certain areas like satellite mass production, but still needs breakthroughs in heavy rockets and reliable reusable technologies [6][10]
