As an attractive collector medium for hypervelocity particles, combined with outstanding physical properties and suitable compositional characteristics, silica aerogel has been proved as an ideal capture media for space debris, interplanetary dust and shock-loaded fragments (highly transparent, low-density, highly porous, etc.), which can capture the hypervelocity particles efficiently and nondestructively. On the one hand, silica aerogel capture cells had been deployed in space missions and many researches focusing on the captured particles and track had been done. On the other hand, numerous efforts of modeling and experimental approaches were concluded to estimate the conditions of impact in aerogel. Hörz classified the diverse aerogel track shapes into three broad types (A, B, and C), In addition to straight path, track curvature was exhibited at the result of ground experiment in the available reports. The gently curving carrot-shaped -tracks observed in aerogel was assigned as being due to irregular shape of projectile. That is closer to the actual situation that many space debris have irregular shapes. However, till now, there is almost no complete understanding of the impact behaviors and typical track morphology of irregular particles. Thus, it is worthwhile to analyze track morphology of hypervelocity irregular grains in silica aerogel.
