如果您希望可以时常见面，欢迎标星收藏哦~ 太阳活动的周期约为11年。当太阳表面出现许多黑子时，会发生强烈的爆炸和太阳耀斑。太阳风 通过日冕洞向外喷发，其中一部分物质会朝地球方向飞去，引发磁暴。当太阳等离子体到达地球并 引发磁暴时，还会产生另一种效应——一种对上层大气的加热现象。大气层被加热后会膨胀，卫星 会感受到更大的飞行阻力，从而脱离轨道，最终坠落。 来源：内容由 每日经济新闻综 合自 参考消息、新华社、新京报、界面新闻，谢谢 。 据 参 考 消 息 援 引 俄 罗 斯 《 共 青 团 真 理 报 》 网 站 6 月 8 日 报 道 ， 埃 隆 · 马 斯 克 的 太 空 探 索 技 术 公 司 （SpaceX）发射的"星链"卫星接连坠落。由美国国家航空航天局（NASA）戈达德航天中心的物 理学家丹尼·奥利维拉领导的研究小组对"卫星雨"进行了研究。 研究小组将卫星坠落的时间与各种自然现象进行对比，发现卫星坠落与太阳活动存在明确的关联。 研究报告指出："我们清楚地发现，当前太阳活跃度的增强对'星链'卫星坠入大气层产生了显著影 响。这是一个研究卫星轨道阻力的绝佳时期，因为在本轮太阳活动高峰期，地球低轨卫星的数量 ...

确实，去年有不少次太阳活动引发了大地磁暴，使得我国国内北方高纬度地区出现了往年看不到的极光。 而磁暴会对大气层产生加热效应，会使得大气层膨胀。星链卫星的轨道并不是真空环境，其多数卫星离地 仅有550km，仍在大气层内。在大气层膨胀后，卫星飞行受到阻力变大，破坏了原有的受力平衡，导致卫 星受地心引力影响而坠向地球。 虽然这个说法可以大概解释为什么星链卫星去年掉了这么多颗，但还是有很多问题没有解决，比如70%的 卫星都不是在强磁暴期间掉的。而且根据估计，与星链卫星同轨道上的通信卫星平均寿命为5年，所以掉 卫星很可能也跟预估寿命到了有关，反正也用了5年，是时候该更新换代了。但随着在轨卫星的数量越来 越多，以后或许能看到一年掉几千颗卫星的情况。 据俄罗斯《共青团真理报》昨日报道，马斯克的SpaceX星链卫星去年出现坠落数量剧增的情况。虽然星链 卫星也存在计划性报废的说法，但去年的坠落数据大大超过了往年的范围。 SpaceX从2019年开始向天上发射星链卫星，截至2025年5月10日，他们总共发射了8514颗星链卫星，其中 有7395颗在轨。而随后的5月16日，SpaceX达成了今年发射第1000颗星链卫星的成就，可以 ...
