SpaceX“星链”卫星大批坠落
Bei Jing Shang Bao· 2025-06-09 16:36
据了解,"星链"卫星是马斯克太空探索技术公司旗下的"全球卫星宽带"项目,该项目计划为包括偏远地 区在内的全球"任何地方"提供卫星宽带。由于SpaceX研发出的猎鹰火箭的相对低成本和强大运力,"星 链"卫星可以频繁发射,一次发射可以将几十颗卫星送上太空。在升空后,有不少"星链"卫星会主动进 行升轨操作,这是因为火箭发射升空后,星箭分离的轨道高度较低,所以需要卫星自主升轨。 不过,数量过多的"星链"卫星也引起了一些麻烦,如2021年我国天宫空间站曾为了躲避马斯克的"星 链"卫星进行两次紧急避碰,而英国One Web公司旗下卫星也曾险些和"星链"卫星发生碰撞事件。因 此,有天文学家批评称,由于地球外层空间有限,数目繁多的"星链"卫星也更易增加碰撞事件发生的概 率,形成更多的太空碎片,危害宇航员的生命安全。 SpaceX官网称,这批"星链"卫星已经设计为跌入大气层时会自动销毁,这意味着不会产生轨道碎片,也 不会有卫星部件撞击地面,"'星链'团队为减少轨道碎片做出了巨大努力"。 太阳风暴活动日益频繁,正在影响地球卫星,尤其是马斯克旗下太空探索技术公司(SpaceX)的"星 链"卫星一段时间来接连坠落。美国国家航空航天局 ...

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 ...

马斯克的星链卫星坠落数量异常增加,罪魁祸首可能是太阳

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 ...
马斯克的“星链” 卫星大批坠落,SpaceX 商业版图受挫
Xin Lang Cai Jing· 2025-06-09 07:45
Core Insights - SpaceX's Starlink satellites have experienced a significant increase in the number of satellites falling from orbit, with 583 satellites lost to date, approximately one in every fifteen satellites launched [1][3] - The increase in satellite falls is correlated with heightened solar activity, which affects atmospheric conditions and increases drag on low Earth orbit satellites [1] - Starlink aims to provide global high-speed internet access through a large constellation of satellites, with a manufacturing cost of $250,000 to $500,000 per satellite and launch costs of approximately $60 million per mission [2] Group 1 - The number of Starlink satellites that fell in 2021 surged to 78, with 99 in 2022 and 88 in 2023, while 316 satellites burned up in the atmosphere last year [1] - The current solar activity peak has led to increased atmospheric heating, causing the atmosphere to expand and increasing drag on satellites, resulting in more frequent falls [1] - Starlink's business model integrates satellite manufacturing, launching, and operational services, creating a comprehensive commercial ecosystem [2] Group 2 - Starlink satellites are designed for low orbits with an average lifespan of five years, and the user base is projected to exceed 5 million by 2025, covering various sectors including aviation and maritime [3] - The launch of direct mobile connectivity services in 2023 aims to expand Starlink's offerings, including SMS, voice calls, internet access, and IoT functionalities [3] - The increase in satellite falls contributes to space debris, posing risks to other spacecraft and requiring significant investment for satellite maintenance and replacement [3]
马斯克的“星链”卫星突然大批坠落,NASA揭秘“卫星雨”成因

Core Viewpoint - The article discusses the increasing number of Starlink satellites falling from orbit, linking this phenomenon to heightened solar activity, which affects satellite drag and leads to their descent into the atmosphere [1][2]. Group 1: Satellite Performance and Loss - SpaceX's Starlink program has launched 2,091 satellites since its inception in 2015, achieving only 5% of its total goal of 42,000 satellites [5]. - The number of satellites lost has escalated, with 583 satellites reported lost to date, including 316 that burned up in the atmosphere last year [1][4]. - The average lifespan of satellites in low Earth orbit is estimated to be around 5 years, necessitating frequent replacements [2][5]. Group 2: Solar Activity Impact - Research indicates a clear correlation between satellite falls and solar activity, particularly during periods of increased solar intensity [1][2]. - Approximately 70% of satellite losses occurred during moderate to weak geomagnetic storms, suggesting that prolonged exposure to these conditions may gradually degrade satellite orbits [2]. Group 3: Business Model and Market Potential - Starlink aims to provide global satellite broadband, particularly targeting remote areas, with a monthly user fee of $99 and a terminal cost of $499 [5]. - Despite the large scale of the Starlink project, the profit margins are reportedly low, raising questions about the long-term viability of its business model [5]. Group 4: Military Applications - The true value of Starlink may lie in its military applications, potentially serving as a replacement for GPS with superior speed and accuracy [7]. - Starlink satellites can support advanced military operations by providing low-latency communication and extensive reconnaissance capabilities [7][8].

Trade Negotiations - The US trade negotiation team has extended its stay in India, indicating progress in discussions aimed at finalizing a limited trade agreement that may lead to the cancellation of a 26% "reciprocal tariff" on Indian goods imposed by the Trump administration [1][2] - The negotiations are focused on reaching consensus on tariff reductions in the agriculture and automotive sectors before a July 9 deadline, with an emphasis on enhancing market access and reducing trade barriers [2][3] - India's exports to the US increased by nearly 28% year-on-year from January to April, reaching $37.7 billion, while imports rose to $14.4 billion, resulting in a trade surplus [2] Impact of Tariff Policies - The tariff policies of the Trump administration have significantly suppressed cargo shipments to the US, leading to a 25% decrease in cargo volume at the Port of Los Angeles in May [4] - The decline in cargo volume has broader implications for the logistics economy in Los Angeles, with a 1% drop in port cargo volume potentially resulting in the loss of 2,769 jobs and threatening an additional 4,000 jobs [4] Starlink's Progress in India - India has granted a key license to Elon Musk's Starlink, moving the satellite service provider closer to launching commercial internet services in the country [5][6] - The approval comes amid public disputes between Musk and Trump, which could jeopardize Starlink's contracts worth billions with the US government [5] - Starlink faces challenges in pricing, as mobile data costs in India are among the lowest globally, and it must also secure additional approvals and demonstrate compliance with local regulations [6]
