Starlink的卫星机队不断壮大,正在增加大气再入大气层,释放有害微粒,并有长期气候和臭氧破坏的风险。 Starlink’s growing satellite fleet is increasing atmospheric re-entries, releasing harmful particles and risking long-term climate and ozone damage.

卫星巨型星座的激增,主要来自SpaceX的Starlink,正在加速大气再入大气层,释放铝和其他颗粒,这些颗粒可能破坏臭氧水平,给高层大气发热,并改变气候模式。 A surge in satellite megaconstellations, primarily from SpaceX’s Starlink, is accelerating atmospheric re-entries, releasing alumina and other particles that may disrupt ozone levels, heat the upper atmosphere, and alter climate patterns. 有近15,000颗运行中的卫星和数以百万计以上的计划,每颗重达1,250公斤,重返大气层的碎片正在增加,造成地面风险——例如加拿大和澳大利亚的碎片着陆——并增加了轨道碰撞威胁。 With nearly 15,000 active satellites and plans for millions more, each weighing up to 1,250 kg, re-entry debris is increasing, posing ground risks—such as fragments landing in Canada and Australia—and raising collision threats in orbit. 科学家们警告说,可能会对环境造成长期损害,包括臭氧消耗和大气变化,而目前的数据差距和全球监管的缺乏则阻碍了全面评估。 Scientists warn of potential long-term environmental harm, including ozone depletion and atmospheric changes, while current data gaps and lack of global regulation hinder full assessment. 没有协调的国际监督,无节制地扩大卫星发射有可能造成不可逆转的大气影响。 Without coordinated international oversight, the unchecked expansion of satellite launches risks irreversible atmospheric impacts.
