报道提到，美国近地轨道实验室公司（LeoLabs）表示，其已探测到"数十枚"可能由此次事件产生的太空 碎片，而后续技术分析可能还会发现更多碎片。该公司认为，这颗卫星高度迅速下降，表明异常更可能是 由内部问题引发，并非与其他太空物体发生碰撞。 路透社称，美国太空部队负责太空目标追踪的部门尚未就碎片数量回应置评请求。 原标题：SpaceX罕见披露：一卫星疑似"爆炸坠落" 编辑：王乙竹 责编：吴光亮 审核：张松涛 环球时报消息，据路透社19日报道，美国太空探索技术公司（SpaceX）表示，其旗下"星链"（Starlink）的 一颗在轨卫星当地时间17日突发故障，在约418公里高度与地面失去通信联系，并产生"少量"太空碎片。 正准备在太空部署的一批"星链"卫星，图源：SpaceX "星链"在社交平台X的官方账号12月19日发消息称，发生异常的是编号为35956号的"星链"卫星。事发时， 卫星推进剂贮箱发生泄漏，其轨道半长轴在短时间内衰减约4公里，并释放出少量可追踪、相对速度较低 的物体，显示卫星疑似发生爆炸类异常。目前，该卫星仍保持基本完整，正处于翻滚状态，预计将在数周 内坠入地球大气层并完全烧毁。 SpaceX公司 ...

Core Viewpoint - The article highlights the increasing concern over space debris, which poses significant risks to spacecraft and astronauts, as evidenced by the recent incident involving the Shenzhou 20 mission being delayed due to suspected collision with space debris [1] Group 1: Space Debris Overview - Space debris, also known as "space junk," includes various objects in Earth's orbit that are no longer operational, ranging from defunct satellites to tiny fragments [1] - As of 2024, there are over 1 million pieces of debris larger than 1 centimeter in space, primarily resulting from satellite disintegration and rocket collisions [1] - A notable incident in 2009 involved a collision between Iridium 33 and the defunct Cosmos 2251 satellite, generating thousands of trackable debris pieces [1] Group 2: Risks and Challenges - Small debris poses a significant challenge due to its high velocity and potential to cause severe damage to spacecraft, particularly affecting heat shield integrity during re-entry [2] - There are approximately 36,000 pieces of debris larger than 10 centimeters in near-Earth orbit, and collisions are not rare occurrences [2] Group 3: Regulatory and Mitigation Efforts - There is currently a lack of international legal frameworks for space debris management, although various countries, including China, are working to establish guidelines [2] - The United Nations has set forth guidelines to mitigate space debris, including a recommendation that space objects should not remain in orbit for more than 25 years [2] - China has implemented regulations for small satellites, mandating that those operating above 2,000 kilometers should actively move to a "graveyard" orbit [2] Group 4: Technological Solutions - Multiple countries are exploring cost-effective and efficient methods for debris removal, such as using nets to capture debris and incinerate it in the atmosphere [3] - China's space agencies have recognized the threat of space debris and have taken preventive measures, including the installation of debris protection devices during the Shenzhou 20 mission [3]
