近地轨道“大拥堵”“太空交管”来破局

Group 1 - The near-Earth orbit has become one of the most crowded and dangerous areas in the solar system, with over 12,000 active satellites and tens of thousands of space debris orbiting the Earth [2] - The altitude range of 400 to 600 kilometers is identified as the most congested zone, where various satellites, including China's space station and the US Starlink satellites, operate at speeds close to 8 kilometers per second, leading to potential collision risks [2] - A collision between two satellites could result in catastrophic consequences, creating thousands of high-speed debris pieces that could further collide with other satellites, leading to a domino effect and potentially forming a lethal debris belt around the Earth [2] Group 2 - In response to the threat of space debris potentially trapping humanity on Earth, China is actively exploring solutions, including the "Star Eye" space awareness constellation plan launched by a Chinese aerospace company [3] - The "Star Eye" plan consists of 156 satellites designed to monitor and track tens of thousands of targets in space, creating real-time digital records for each satellite and debris, and providing collision risk calculations and warnings [3] - Establishing a global unified "space traffic regulation" is deemed essential for ensuring the safety of thousands of satellites and protecting the common interests of humanity [3]
