Chelyabinsk Meteor • High-fidelity Simulation Offers Insight into 2013 Atmospheric Disruption 10.3.23 VIDEO: The meteor is shown as a contour of the damage state (white intact, black fully-damaged). Shock-heated air nodes are displayed as points colored by their temperature. Initially fracture begins at the rear of the object. The crack then propagates forward eventually splitting the object into three coherent fragments. The fragments are disrupted shortly thereafter. Image courtesy of LLNL Pla
