"Revealed: Decades of Inaccurate Space Nuclear Explosion Calculations, Says Los Alamos Scientist"

A scientist at Los Alamos National Laboratory has discovered errors in mathematical calculations related to the effects of nuclear explosions in space, which have gone undetected for nearly 50 years. These errors have impacted our understanding of the influence of electromagnetic waves on the dispersal of trapped electrons in the Earth's magnetic fields. The discovery offers an opportunity to improve protections for space technologies and better predict the threat and efficacy of radiation belt remediation strategies. The errors have implications for the damage caused to satellites by artificial radiation belts formed after nuclear explosions in space, and they conflict with quasilinear theory, a cornerstone for existing models used to understand spacecraft protection.

"Enhancing Satellite Safety Through Space-Physics Error Correction"

Researchers have corrected a 50-year-old error in the math used to understand how electromagnetic waves scatter electrons trapped in Earth's magnetic fields, leading to improved models of artificial radiation belts and better predictions of their impact on space technology. The discovery of these errors will help scientists improve their understanding of how high-altitude nuclear explosions could produce artificial radiation belts and impact space technology, potentially leading to better protection for satellites and space assets.
