Title: Optimizing Meteorite Recovery and Impact Predictions through Physical Modeling

Abstract: Understanding meteor phenomena is crucial for efficiently recovering meteorites, forecasting meteor showers, studying atmospheric properties, and assessing the risks posed by space objects to both in-orbit and ground-based infrastructure. By conducting observations and analyzing meteor events, we can predict the outcomes of impacts and promptly identify surviving meteorite fragments. Through dimensional analysis, we have developed a robust physical model that reduces the number of unknowns without requiring them to be preset. The model accurately estimates changes in mass, velocity, luminosity, and predicts the duration of meteor events. It has been successfully applied to various meteor events, including the recovery of meteorites such as Annama and Ozerki, and more recently, quantifying meteor phenomena in the atmosphere of Venus. The model’s versatility is further demonstrated through its application to larger-scale impacts, including Chelyabinsk, Canyon Diablo, Sikhote-Alin, and the Tunguska event.
