空间碎片威胁到地球轨道,危及关键服务,并引发全球清理工作。 Space debris threatens Earth's orbit, risking critical services and sparking global cleanup efforts.

空间碎片正日益威胁国际空间站和卫星,引起对Kessler综合症的恐惧——这种碰撞的连锁反应可能使地球轨道无法使用。 Space debris is increasingly threatening the International Space Station and satellites, raising fears of Kessler Syndrome—a chain reaction of collisions that could render Earth's orbit unusable. 1957年以来,650多起事件产生了碎片,包括2009年的碰撞,共产生2 000件碎片。 Since 1957, over 650 events have created debris, including a 2009 collision that produced 2,000 pieces. 碎片对全球定位系统、互联网和电视服务构成风险。 The debris poses risks to GPS, internet, and TV services. 联合国和欧空局拥有47 000多个可追踪物体和数以百万计的较小碎片,正在探索清理技术和监管框架。 With over 47,000 trackable objects and millions of smaller pieces, the UN and ESA are exploring cleanup technologies and regulatory frameworks.
