What is it about?
As a result of quickly growth in the number of satellites, the amount of orbital debris is growing rapidly. Over the past twenty years, LEO debris amount has increased rapidly, which led to increase the probability of collision that cause the generation of debris rate exceeds the rate at which debris deorbit, and fall into the atmosphere and burn up.

Why is it important?
Space debris represents threat to operational spacecrafts in Earth orbit because this debris is travelling at very high orbital speeds, about (7-8 km/s) in Low Earth Orbit (LEO).
Perspectives
The probability of spacecraft collisions with different sizes of orbital debris and with other satellites which operating in the same orbit during orbital lifetime must be determined and the required change in velocity for maneuvers necessary to reentry atmospheric within 25 years must be calculated.
