In Proceedings of the International Astronautical Congress, Guadalajara, Mexico, 2630 September 2016. Since these two points are not considered in the current version of the NASA SBM, it is also shown that the NASA model may overestimate the fragment distributions when impacts are not central or the ratio between impactor size and target size is small [, The second set of simulated collisions involved GEO telecommunication satellites with sizes comparable to the Intelsat spacecraft family [, Among the main results collected by this work and available in [, The third set of simulations investigated potential collisions involving ENVISAT as target, see, The simulation campaigns performed with the CSTS allowed us to conclude that there is room for improvement in the fragmentation models currently employed (e.g., NASA SBM) and, in particular, in the definition of the threshold for catastrophic impacts. The study was conducted with the purpose of investigating the transition between sub-catastrophic and catastrophic collision while increasing the impactors kinetic energy, and the effect of impact point and encounter configuration on the collision severity. In fact, the same value of EMR can produce different levels of damage if the impact does not occur on the targets center of mass or the impactors kinetic energy results from different combinations of impactor mass and velocity.
