仅200米，中美卫星惊险“擦肩”，SpaceX高管指责中国企业，中企反驳，究竟谁在碰瓷？航天专家解读→

Core Viewpoint - The recent close approach of a Chinese satellite to a SpaceX Starlink satellite has raised concerns about space safety and coordination among satellite operators [1][3]. Group 1: Incident Details - SpaceX's Starlink Vice President Michael Nichols reported a 200-meter close approach between a Chinese satellite and a Starlink satellite, claiming no coordination was made for the launch [1]. - China Aerospace Science and Technology Corporation (CASC) responded, stating that all their launches use ground-based space awareness systems to avoid collisions, emphasizing this is a mandatory procedure [1][3]. - CASC clarified that if the close approach event is confirmed, it occurred 48 hours after the satellite payload separation, indicating the launch mission had already concluded [3]. Group 2: Starlink Operations and Challenges - Starlink has faced multiple collision threats, including two incidents in 2021 where Starlink satellites came close to the Chinese space station, prompting emergency collision avoidance maneuvers [3]. - As of February 2025, Starlink has over 6,750 satellites in orbit, with plans to expand to a constellation of 42,000 satellites [3]. - International space experts noted that while the number of Starlink satellites is significant, the greater threat to space safety comes from the larger quantity of space debris [3]. Group 3: Maneuvering and Coordination Issues - From December 2024 to May 2025, Starlink satellites executed over 140,000 maneuvers to avoid collisions, which is 2.8 times more than the previous six months [4]. - The frequent maneuvers complicate collision predictions for other organizations, as the operational status of satellites can change rapidly [4]. - Experts emphasized the need for responsible spacefaring nations to notify relevant parties when satellites change orbits to prevent collisions, especially for operational satellites [5]. Group 4: Call for Improved Coordination - Nichols highlighted that the lack of coordination among satellite operators poses risks for close approaches in space, calling for a change in this practice [6]. - CASC indicated that a new cooperative relationship is needed between the two emerging space ecosystems to enhance safety and coordination [6].
