“星链”将降低约4400颗卫星轨道高度

Core Viewpoint - The company plans to lower the operational altitude of approximately 4,400 Starlink satellites from about 550 kilometers to approximately 480 kilometers by 2026 to enhance space safety and reduce the risk of space debris [1][2] Group 1: Satellite Operations - The current number of operational Starlink satellites in orbit exceeds 9,000 [1] - The altitude reduction aims to allow failed satellites to re-enter the atmosphere more quickly, with satellites at 480 kilometers taking only a few months compared to over four years at 550 kilometers [1] - The move is also intended to distance Starlink satellites from the increasingly crowded orbital region between 500 to 600 kilometers, thereby minimizing risks associated with debris and coordination issues [1] Group 2: Safety Concerns - A previous incident in December 2025 involved a Starlink satellite that malfunctioned, resulting in a rapid altitude drop of 4,000 meters and the creation of debris, highlighting potential safety threats to other spacecraft [1] - Currently, there are two completely non-functional Starlink satellites remaining in orbit [2] - The company is coordinating with U.S. regulatory agencies and other satellite operators to prevent space traffic conflicts during the planned altitude reduction [2]
