The simulations of the long term evolution of the space debris population, under realistic assumptions, show how the driving factor in the future environment will be mostly the breakup of large spacecraft and rocket bodies in LEO.
The present distribution of intact objects is a good proxy to quantify the catastrophic collision risk and consequences in the coming decades. For this reason, it is important to understand the effects of selected ``typical'' collisional fragmentations on the long term evolution of the debris population, as a function of the main driving parameters, with the goal of measuring the danger represented by ``typical'' classes of space objects
