DURING HYPERVELOCITY IMPACT CAPTURE OF COMET 81P/WILD 2 DUST IN THE STARDUST MISSION SILICA AEROGEL BOTH COMET DUST AND PRE-FLIGHT AEROGEL WERE MODIFIED. THE EXTREMES RANGE FROM COMPLETE LOSS OF TEXTURES AND MINERALS WHEN COMET DUST INTERACTED WITH SILICA AEROGEL BUT PRESERVING THE BULK CHEMICAL SIGNATURES OF THE COMET DUST TO SURVIVAL OF HIGHLY ORDERED MINERALS WITH A THIN QUENCHED SILICA GLASS RIND. BROADLY SPEAKING MOST OF THE NANOMETER SCALE PARTICLES FROM THE LOOSE WILD 2 AGGLOMERATES WERE ASSIMILATED IN VESICULAR LOW-MG CA AL MN CR SILICA GLASS WITH NUMEROUS FE-NI-S COMPOUNDS (~1 UP TO ~100NM). DESPITE THE COMPLETE LOSS OF PETROGRAPHIC TEXTURES IT IS POSSIBLE TO RECONSTRUCT THESE ORIGINAL WILD 2 AFTER CORRECTION FOR A CHEMICAL CONTAMINANT BACKGROUND. THE BACKGROUND CORRECTED COMPOUND COMPOSITIONS ARE MOSTLY NI-FREE LOW-S FE-S GRAINS. APPARENTLY INTACT SURVIVING MINERALS FROM ~500NM TO MANY MICRONS IN SIZE ARE FOUND ALONG THE TRACK WALLS AND IN THE TERMINAL PARTICLES. MANY MINERAL GRAINS ARE FRACTURED AND SOME SHOW UNUSUAL FEATURES THAT SUGGEST (ALMOST) DIFFUSION-LESS RESPONSES TO THE SHORT-LIVED THERMAL REGIME OF HYPERVELOCITY CAPTURE. I WILL CHARACTERIZE SURVIVING MINERALS AND FLIGHT AEROGEL IDENTIFY THE EXTENT OF MODIFICATIONS DEFINE THE COMPLEX AND CHAOTIC INTERACTIONS AND CONSTRAIN THE PHYSIOCHEMICAL ENVIRONMENTS CAUSING MODIFICATIONS USING HRTEM IMAGING AND ATTENDANT CRYSTALLOGRAPHIC AND CHEMICAL ANALYTICAL CAPABILITIES.
