根据联合国和平利用外太空委员会(United Nations Committee on the Peaceful Uses of Outer Space,COPUOS)于官网发布的资料,中国常驻联合国代表团向联合国秘书长提文件表示,美国太空探索技术公司(SpaceX)发射的星链(Starlink)卫星,在今年先后两次接近中国太空站,构成站内太空人生命安危。出于安全考量,中国太空站两次实施"紧急避碰"。
人就怕没知识,少常识,象周扒皮同学一样活着:
With the prospect of a total of some 65,000 SpaceX, Amazon, OneWeb, and Starnet/GW satellites orbiting in just a couple years, Boley and astronomer Samantha Lawler made predictions for their light pollution effects in a new research paper that’s currently going through peer review. (They aren’t affiliated with any of the satellite makers.) Based on observations and models of Starlink satellites’ brightness, they find that at latitudes near 50 degrees North and South—affecting people in Canada and Europe, for example—satellites will make up between 7 and 14 percent of lights one can see by telescope, and about one in 10 of those seen by the naked eye.

只有不到千分之一的居民需要使用StarLink服务,但它已经占用了这些地区头顶近15%的近地空间资源,10%的夜晚星空光源。已经使这些地区的地表星空探测不再可能。
根据联合国和平利用外太空委员会(United Nations Committee on the Peaceful Uses of Outer Space,COPUOS)于官网发布的资料,中国常驻联合国代表团向联合国秘书长提文件表示,美国太空探索技术公司(SpaceX)发射的星链(Starlink)卫星,在今年先后两次接近中国太空站,构成站内太空人生命安危。出于安全考量,中国太空站两次实施"紧急避碰"。

据中共官方喉舌《环球网》今 ( 27 ) 日报导,中国向联合国提出的文件指出:2021 年,中国载人航天工程实施了 5 次发射任务,成功将太空站"天和核心舱"、"天舟二号"和"天舟三号货运飞船"、"神舟十二号"和"神舟十三号载人飞船"发射入轨。于此期间,SpaceX 发射的星链卫星先后两次接近中国太空站。出于安全考虑,空间站组合体分别于 7 月 1 日和 10 月 21 日实施对美国星链卫星的预防性碰撞规避("紧急避碰")
第一次紧急避碰:
2021 年 5 月 16 日至 6 月 24 日,美国星链-1095 卫星持续降轨机动至平均轨道高度 382 千米后,保持在该轨道高度运行。 7 月 1 日,该卫星与中国空间站间出现近距离接近事件。出于安全考虑,中国太空站于 7 月 1 日晚主动采取紧急避碰,规避了两目标碰撞风险。
第二次紧急避碰:
2021 年 10 月 21 日,美国星链-2305 卫星与中国太空站发生近距离接近事件。鉴于该卫星处于连续轨道机动状态,机动策略未知且无法评估轨道误差,存在与太空站碰撞风险。为确保在轨太空人安全,中国太空站于当日再次实施紧急避碰,避免两目标碰撞风险。
