NASA rocket takes first multi-point look inside radio-disrupting clouds
📌 概要
NASA一枚探空火箭携带五个探测器同时穿过高空偶发E层，首次实现对该电离层现象的多点同步观测。偶发E层由陨石烧蚀产生的金属蒸气构成，会干扰无线电通信。观测显示其内部结构复杂程度远超此前认知，为研究其形成与消散机制提供了新数据。
⚡ 关键要点
- ▸NASA探空火箭首次以五探测器多点同时穿透偶发E层观测
- ▸偶发E层由流星烧蚀金属蒸气形成，可干扰无线电通信
- ▸观测结果首次揭示该云层内部结构存在出乎意料的复杂性
High above Earth, thin veils of metallic haze drift through the edge of space. Known as sporadic E layers, these high-altitude "clouds" form from the vaporized dust of burned-up meteors, earning their name from the unpredictable way they emerge and then dissipate. Now, new results from a NASA sounding rocket—a suborbital research rocket—that flew five detectors through one of these layers simultaneously reveal unexpected complexity in the layer for the first time.
