Geometrical analysis of the microcraters found on LDEF samples

Diameters (D) and depths (T) of microcraters found on LDEF samples were measured and their origins were deduced by the (D/T) ratios, which distinguish projectile materials. From the results, one iron and several stony projectiles could be recognized.
