太空垃圾：看不見的軌道危機Space Debris: The Invisible Orbital Threat
退役衛星、廢棄火箭與碰撞碎片正不斷增加，對在軌衛星、太空站與未來任務構成高風險威脅。即使微小碎片，也可能因高速運行而造成嚴重損害。
Retired satellites, spent rocket stages, and collision fragments are increasing in orbit, threatening active spacecraft, space stations, and future missions. Even tiny debris can cause severe damage at orbital speeds.
軌道安全：建立太空交通秩序Orbital Safety: Managing Space Traffic
地面雷達、光學望遠鏡與軌道數據分析，正在協助追蹤太空物體並預測碰撞風險。未來，國際協調與資訊共享將成為軌道安全的重要基礎。
Ground radar, optical telescopes, and orbital data analysis help track objects and predict collision risks. In the future, international coordination and data sharing will be essential for orbital safety.
太空垃圾清除：讓衛星獲得第二次生命Debris Removal: Giving Space Assets a Second Life
在軌服務與主動清除技術正在發展，包括檢查、維修、補充燃料與移除大型失效物體，以延長衛星壽命並減少新垃圾產生。
On-orbit servicing and active debris removal are advancing, including inspection, repair, refueling, and removal of large defunct objects to extend satellite life and reduce new debris.
永續太空：守護人類共同的未來Sustainable Space: Protecting a Shared Future
更負責任的衛星設計、安全退役與國際合作，將有助於維護可長久使用的軌道環境。守護太空，就是守護未來世代探索宇宙的權利。
More responsible satellite design, safe end-of-life disposal, and international cooperation will help preserve a usable orbital environment. Protecting space means protecting future generations' right to explore it.
