Technology Today Fall 1999 cover image

To demonstrate the viability of performing seismology on asteroid 433 Eros, Southwest Research Institute scientists performed computations of impactor and explosive sources on local, high-resolution meshes (background) and transferred the resulting stress waves to a full model of the asteroid (foreground). The article,Cracking a Cosmic Mystery, describes the techniques used and presents computation results.
