Recently analysed hypervelocity impact data from retrieved satellites are summarised. Analyses of perforation data show that mean densities are low (around 1.5-2 $$g-cm^3$$), impact velocities are consistent with radar meteor observations and that high aspect ration particles are not found. Mean data for $$F_{max}>30\mu m$$ agrees well with the Grun et al. Interplanetary flux model, though there is evidence of a strong bias towards the Earth apex of motion direction. For $$F_{max}<30\mu m$$ the data at LDEF's altitude is dominated by space debris.
