LINK<\/strong><\/a><\/p>\n\n\n\n“The Maoming meteorite, which fell in Guangdong Province, China, on May 28, 2025, represents the second-largest witnessed meteorite recovery event in China since 1949, with a total recovered mass of 423\u2009kg. This study presents an integrated analysis of its petrology, mineral chemistry, and aerodynamic behavior to reconstruct the complete atmospheric entry-to-impact sequence. Fresh samples were examined using optical microscopy, electron probe microanalysis, and density measurements, while the entry trajectory was simulated using a fourth-order Runge\u2013Kutta model constrained by impact crater morphology and atmospheric data. Based on mineralogical homogeneity and shock-weathering features, Maoming is classified as an L5 ordinary chondrite (shock stage S3, weathering grade W1) with a double-layered fusion crust indicating peak temperatures of 1410\u00b0C\u20131615\u00b0C. Aerodynamic modeling, based on a constrained initial velocity of ~15\u2009km\/s, yields an entry angle of 13.9\u00b0 and a terminal impact velocity of 267.23\u2009m\/s at a trajectory angle of 65\u00b0. The simulated penetration depth (2.98\u2009m) closely matches field observations (~3\u2009m), validating the reconstructed dynamics. Despite its friable, fractured structure, the meteoroid survived atmospheric passage without catastrophic disruption, contrasting with typical fragmentation-dominated entries. This case provides critical empirical constraints on the survival of moderately strong, fractured ordinary chondrites under moderate entry conditions. The combined petrological and aerodynamic approach presented here provides a framework for rapid trajectory reconstruction and impact effect quantification. This framework also offers empirical constraints on the trajectory and cratering mechanics of meter-scale, moderately strong meteoroids.”<\/p>\n","protected":false},"excerpt":{"rendered":"
