NASA Rocket Takes First Multi-Point Look Inside Radio-Disrupting Clouds
📌 概要
NASA探空火箭首次对高层大气中干扰无线电通信的“偶发E层”进行多点观测。这些由流星尘埃蒸发形成的金属雾可在80-120公里高度出现和消散，会干扰GPS与无线电信号。新数据有助于理解其形成机制并改进通信与导航预报。
⚡ 关键要点
- ▸NASA探空火箭完成对偶发E层的首次多点观测
- ▸偶发E层由流星烧蚀产生的金属蒸气在高空形成
- ▸该现象会干扰无线电与GPS通信，研究有助于改进预报
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 burnt-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 […]
