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→

Group 1 - SpaceX's Starlink program faced criticism from China Aerospace Corporation after a recent satellite launch resulted in a close approach of 200 meters with a Starlink satellite, which was not coordinated [1][3] - China Aerospace Corporation emphasized that all its launch missions utilize ground-based space awareness systems to select launch windows and avoid collisions with known satellites or debris, highlighting this as a mandatory procedure [1][3] - The close approach incident, if confirmed, occurred 48 hours after the satellite payload separation, indicating that the launch mission had already concluded [3] Group 2 - Starlink has previously faced 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 primary threat to space safety comes from the larger quantity of space debris, rather than the satellites themselves [3][5] Group 3 - 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, complicating collision predictions for other organizations [5] - Starlink satellites are designed to be lightweight with large solar panels, making them susceptible to atmospheric drag, necessitating frequent orbit maintenance [5] - The need for frequent maneuvers is also driven by the requirement to maintain a uniform spatial distribution of the satellite constellation for consistent service [5] Group 4 - Experts highlighted the importance of satellite operators sharing trajectory data to prevent collisions, as uncoordinated maneuvers can lead to dangerous close approaches in space [6] - Michael Nichols from SpaceX stated that the lack of coordination among satellite operators is a significant risk factor in space operations, calling for improved collaboration [6][7] - China Aerospace Corporation acknowledged the need to establish cooperative relationships between the two emerging space ecosystems [7]
