Update Reason: Loaded a new Clarification (English version)

Passive de-orbiting devices (such as drag augmentation, mechanical tethers) are a reliable measure to limit post mission orbital lifetimes, in particular for small missions. However, the increase cross-section also increases the collision risk and (in a worst case) the effect might be neutral. Not all of the cross-section in this case may be sensitive to catastrophic collisions. Flux prediction and vulnerability modelling approaches shall be used to clarify the overall net effect of the passive de-orbiting devices.
