Fragments creation via impact at low speed

Authors have conducted impact tests to investigate the nature of the newly created debris cloud, and then to predict the uncatalogued population and the probability of the secondary impact that all other satellites might be subjected to. These efforts have been conducted especially at low velocity range because of apprehensions about space debris and environment in geosynchronous region. Velocity profile of fragments must be measured to fully validate the fragmentation model, so that a new system using a CCD camera with two strobe lights is adopted to capture the fragmentation process. The captured images enable us to measure initial velocities of the fragments released after impact. In this paper, fragments creation via impact at low speed is reviewed by characterizing both at once velocity and mass distributions.
