STXM analysis found magnesium, cerium, aluminum, sodium and zinc in a 1 µm terminal particle, probably as a glass; Zn-XANES showed the zinc to be oxidized. Fragments along the track are not the same composition as the terminal particle since no Mg, Ce, Al were detected. This terminal particle is likely to be glass from the space craft – from an IDP strike onto a solar panel. The track diameter is 2.5 µm and the aerogel density is 15±1 mg/cm3 derived from 1 absorption image of the keystone (1313eV).
