Core Insights - The European Space Agency and NASA's "Solar Orbiter" mission has successfully entered an inclined orbit, allowing for the first-ever images of the Sun's south pole, marking a significant milestone in solar observation [1] - The spacecraft, launched in 2020, has adjusted its orbital inclination to 17 degrees below the ecliptic plane, enabling the capture of previously unseen solar polar images [1] - The initial images taken in March will aid scientists in improving predictions of solar activity, which follows an approximately 11-year cycle [1] Group 1 - The "Solar Orbiter" has captured rare images of the Sun's south pole, which are crucial for understanding solar activity [1] - The spacecraft's measurements of the magnetic field and high-energy radiation at the Sun's south pole have been released, contributing to a better understanding of solar dynamics [1] - The data collected will enhance the ability to forecast space weather, particularly from the challenging-to-observe polar regions of the Sun [1] Group 2 - The mission is expected to further increase its orbital height, providing clearer views of the solar poles in the future [1] - The solar activity minimum is anticipated to occur in 3 to 4 years, making the understanding of polar magnetic field structures critical for space weather forecasting [1] - The "Solar Orbiter" has also captured images of the Sun's north pole, with data still being transmitted back to Earth [2]

与目前的通信网络相比，"星链"卫星的广泛部署将彻底改变我们的通讯方式，甚至可以将其看作是将互联网从地球的表面提升到了天上，彻底改变了我们对 互联网的认知和使用的方式 至2025年5月，SpaceX"星链"的发射总数已达8514颗，其中就有3.8万颗微小的"星链"v2.0的"小卫星"。其不仅数量惊人，而且以高速、低延迟的通信能力等 先进的技术也大大增强了了了我国的空间信息化基础，促进了我国的国民经济的发展和社会的进步。 近日，"星链"的一大批由马斯克旗下的太空探索技术公司（SpaceX）发射的低轨卫星的"大规模"坠落的事件又一次将这一神奇的"网络"推到了公众的视线 中。近两年来，英国的《独立报》及新德里电视台等外媒的逐一曝光中，揭露了"星链"这款全球最大的5G移动通信卫星互联网的可怕的"暗面"，其不仅"无 孔不入"的广泛的覆盖了全球的几乎所有的角落，而且其所带来的"危害"也日益明显. 如从2020年至2024年间，其所"抛下"的"星链"卫星就有583颗，且其所坠落的"星链"卫星的坠落速度呈现明显的上升趋势，2024年更是多达316颗"星链"卫星 在大气层中烧毁。但从这一奇妙的现象中我们又能领悟到什么呢？ 近几个 ...
