一项新的研究表明,地震监测网络能够探测空间碎片下降时的声震,从而改进在大气重返过程中的跟踪准确性。 A new study demonstrates that earthquake monitoring networks can detect sonic booms from falling space debris, improving tracking accuracy during atmospheric reentry. 研究人员利用来自120多个站点的地震数据,对南加利福尼亚州1.5吨中国模组的2024年降幅进行了测绘,将其定位在比雷达预测的更南近20英里处。 Researchers used seismic data from over 120 stations to map the 2024 descent of a 1.5-ton Chinese module over Southern California, locating it nearly 20 miles further south than radar predicted. 该方法发表在《科学》上,可以帮助更快地查明碎片坠落区,特别是由于SpaceX的Starlink等项目导致卫星数量增加。 The method, published in Science, could help identify debris fall zones more quickly, especially as the number of satellites increases as a result of projects such as SpaceX's Starlink. 虽然没有发现碎片,但这一技术为跟踪不受控制的再入大气层提供了更快的方法,可能有助于今后的脱轨工作,例如美国航天局计划对国际空间站进行处置。 Though no debris was discovered, the technique provides a faster way to track uncontrolled reentries and may help with future deorbiting efforts, such as NASA's planned disposal of the International Space Station. 科学家希望建立一个地震跟踪累留物数据库,并利用风力数据完善模型,但需要更快的分析,以跟上不断上升的轨道拥塞。 Scientists hope to create a database of seismically tracked reentries and refine models using wind data, but faster analysis is required to keep up with rising orbital congestion.
