SpaceX rocket explosion shredded the upper atmosphere
SpaceX's Starship explosion created a large ionosphere hole, affecting GPS reliability. Shock waves altered ionization levels for nearly an hour, highlighting the need for better understanding of atmospheric processes.

A recent study has revealed that the explosion of SpaceX's Starship rocket last year created one of the largest holes ever detected in the ionosphere, a layer of the atmosphere crucial for satellite navigation. The explosion, which occurred on November 18, 2023, resulted in shock waves that transformed the ionosphere into a neutral region for nearly an hour, affecting an area from Mexico to the southeastern United States. Researchers analyzed data from over 2,500 ground stations and found that the shock waves traveled faster than sound, leading to significant disturbances in the ionosphere. This phenomenon raises concerns about the potential impacts on GPS and other satellite-based systems, as the ionosphere's ionization levels can affect radio wave propagation. The study's co-author, Yury Yasyukevich, emphasized the need for a better understanding of atmospheric processes, as the extent of the disturbance was unexpected. The findings, published in Geophysical Research Letters, highlight the implications of both natural and human-induced disturbances on satellite navigation and communication systems, especially as rocket launches become more frequent.
