  abstract = {{M}aterial degradation due to the specific space environment becomes a key parameter for space missions.{T}he use of large surface of brittlematerials on satellites can produce, if impacted by hypervelocity particles, ejected volumes of mater 100 times higher than the impacting one. {T}he presented work is devoted to the use of silica aerogels as passive detectors. {A}erogels have been exposed to the low earth orbit of the {ISS} for 18months. {T}he study describes the aerogels process and the choice of synthesis parameters in such a way to get expected features in terms of porosity,mechanical properties, internal stresses, and transparency. {L}ow-density aerogels (0.09 g⋅cm−3) have been prepared. {T}he control of transparency necessary to see and identify particles and fragments collected is obtained using a base catalysis during gel synthesis. {A}fter return to earth, the aerogels samples have been observed using optical microscopy to detect and quantify craters on the exposed surface. {F}irst results obtained on a small part of the aerogels indicate a large number of debris collected in the materials.},
