1月6日晚,河南郑州、洛阳、开封、新乡等多地网友发现,夜空中出现了一串快速移动的"神秘光点", 蔚为壮观。 网友们表示,这串光点排成直直的一条线,大约有二三十个,约十几分钟后便消失在视线之外。记者发 现,网友们观测到这一现象的时间约在晚间6点半至7点半之间,与此同时,陕西、河北等地的网友也表 示目睹了同样的一幕。针对夜空中的"银河号列车",网友们展开了热烈讨论,也有人给出了直接的答 案:"星链"卫星。 来源:大河报 根据网友们所拍摄的视频,河南省妇女儿童发展中心天文馆馆长李德范确认,这串光点并非不明飞行 物,而是马斯克旗下的美国太空探索技术公司(SpaceX)所发射的"星链"卫星。"这些卫星在轨道上运 行时,其太阳能面板的角度会发生变化,从而反射太阳光。观测这些卫星的最佳时间一般在傍晚和清 晨,因为这两个时间段大气层上方是亮的,星链成串出现,非常醒目。" 李德范表示,随着低轨卫星数量的不断增加,"星链过境"的景象近年来比较常见,通过相关的手机应用 程序,可以查看"星链"卫星过境的具体时间和方位。 根据相关报道,SpaceX公司的目标是建设一个全球覆盖、大容量、低时延的天基通信系统,通过卫星 提供宽带服务,从而 ...
