TL;DR: In this article, a new study has been conducted in the Orbital Debris Program Office at the NASA Lyndon B. Johnson Space Center, using higher fidelity models to evaluate the current debris environment.

TL;DR: The intentional break-up of the Fengyun-1C spacecraft on 11 January 2007 via a hypervelocity collision with a ballistic object created the most severe artificial debris cloud in Earth orbit since the beginning of space exploration.

TL;DR: In this article, the authors analyzed results from 200 Monte Carlo simulations of the future debris environment, using the NASA long-term orbital debris evolutionary model LEGEND, and analyzed the projected debris populations in terms of the mean, median, standard deviation, standard error, and the distribution of the debris populations at the end of the 100-year projection.

TL;DR: In this paper, two new satellite impact experiments were conducted to investigate the outcome of low and hyper-velocity impacts on two identical target satellites, which were completely fragmented in both experiments, although there were some differences in the characteristics of the fragments.

TL;DR: In this paper, two new satellite impact tests were conducted in order to investigate on the outcome of low and hyper-velocity impacts on two identical target satellites, and the similarity in mass distribution of fragments between low and high velocity impacts encourages the development of a general-purpose distribution model applicable for a wide impact velocity range.
