TLDR
In this article, the authors present the results of a set of parametric EVOLVE 4.0 studies and show that explosion suppression alone effects only a minor change in the long-term environment and that post-mission disposal implementation is required to significantly reduce it.About:

Journal ArticleDOI
A sensitivity study of the effectiveness of active debris removal in LEO
TL;DR: In this article, a removal criterion based upon mass and collision probability is developed to rank objects at the beginning of each projection year, with removal rates ranging from 2 to 20 objects per year, starting in the year 2020.
Journal ArticleDOI
Instability of the Present LEO Satellite Populations
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.

The many futures of active debris removal
Adam E. White,Hugh G. Lewis +1 more
TL;DR: In this paper, the influence of four key parameters describing launch and explosion rates, the magnitude of solar activity and the level of post-mission disposal compliance on the effectiveness of active debris removal (ADR) to reduce the LEO debris population was investigated.
Journal ArticleDOI
A LEO satellite postmission disposal study using legend
TL;DR: In this paper, two postmission disposal (PMD) parametric analyses based on the high fidelity NASA orbital debris evolutionary model LEGEND were conducted to evaluate the impact of a prolonged spacecraft mission lifetime and a lower PMD success rate on the long-term debris environment.

Designer Satellite Collisions from Covert Cyber War
TL;DR: In this paper, the U.S. maintains its space superiority to ensure it has the capabilities modern warfare requires for successful operations, but the difference with earlier periods in space is there is not a blatantly publicized arms race in space, but instead a covert challenge to UAVs.

Collision frequency of artificial satellites: The creation of a debris belt
TL;DR: In this article, a mathematical model was used to predict the rate at which such a belt might form, under certain conditions the belt could begin to form within this century and could be a significant problem during the next century.
Journal ArticleDOI
Collisional cascading: The limits of population growth in low earth orbit
TL;DR: In this paper, it is shown that cascading collisions will control the future debris environment with no, or very minor increases in the current low-earth-orbit population with no explosion fragments and expended rocket bodies and payloads.

Orbital Debris from Upper Stage Breakup
TL;DR: In this paper, the effects of launch vehicle upper-stage breakup on the orbital debris scenario were discussed. And the authors discussed the prospects for and the economics of the future removal of orbital debris, collision probabilities in GEO, current operational practices for Delta second stage breakup prevention, breakup-precluding modifications to the Ariane third stage and the safing of the H-1 second stage after spacecraft separation.
