2022年2月3日SpaceX发射的49颗Starlink卫星提供了一个引人入胜的例子，说明即使是温和的太空天气也会产生重大的实际和经济后果。与一次小型地磁暴有关的大气阻力增强导致49颗发射卫星中的大多数丢失。虽然这是SpaceX在过去3年中的第36次发射，但这是第一次经历暴风雨天气。我们预计，随着第25个太阳活动周期向2025年预计的峰值攀升，将出现更多的太空风暴天气。随后于2月21日进行的Starlink发射使用了300公里的较高初始轨道，将有效载荷从49颗卫星减少到46颗卫星，可以认为是对两周前经历的空间天气损失的敏捷反应。讨论了空间工业和空间气象界应吸取的经验教训，包括更好地对话，对与适度事件相关的空间气象风险有细致入微的了解，但也有机会调查诸如极低和极低地球轨道等相对未探索区域的空间环境。
The 3 February 2022 launch of 49 of SpaceX's Starlink satellites has provided a fascinating example of how even modest space weather can have significant practical and financial consequences. Enhanced atmospheric drag associated with a minor geomagnetic storm led to the loss of the majority of the 49 launched satellites. Although the 36th launch by SpaceX in the past 3 years, it was the first that experienced stormy space weather. We expect more stormy space weather as Solar Cycle 25 ramps up toward its peak expected in 2025. A subsequent Starlink launch on 21 February used a higher initial orbit at 300 km, reducing the payload from 49 to 46 satellites, and can be considered an agile response to the space weather losses experienced 2 weeks earlier. Lessons to be learned by the space industry and the space weather community are discussed, including a better dialog, nuanced understanding of space weather risks associated with modest events, but also an opportunity to investigate the space environment in relatively unexplored regions such as very low and high low Earth orbits.
