Journal ArticleDOI
Risks in Space from Orbiting Debris
TL;DR: The LEGEND (LEO-to-GEO Environment Debris model) is a high-fidelity three-dimensional physical model developed by the U.S. National Aeronautics and Space Administration (NASA) that is capable of simulating the historical environment and the evolution of future debris populations as discussed by the authors.
Journal ArticleDOI
An active debris removal parametric study for LEO environment remediation
TL;DR: A new sensitivity study on using ADR to stabilize the future LEO debris environment is described, using the NASA long-term orbital debris evolutionary model, LEGEND, to quantify the effects of several key parameters, including target selection criteria/constraints and the starting epoch of ADR implementation.
Journal ArticleDOI
Controlling the growth of future LEO debris populations with active debris removal
TL;DR: In this paper, the authors presented a comprehensive study based on more realistic simulation scenarios, including fragments generated from the 2007 Fengyun-1C event, mitigation measures, and other target selection options.
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.

History and consequences of on-orbit break-ups
TL;DR: In this article, the authors identify two known mechanisms of artificial satellite break-ups: accidental (e.g., propulsion-related malfunctions) and deliberate on-board explosions, which constitute one-third of all satellites currently in orbit about the Earth.
A guide to using meteoroid-environment models for experiment and spacecraft design applications
TL;DR: In this article, a method was derived for transforming a meteoroid flux, defined relative to the earth and expressed as a function of meteoroid mass, velocity, and mass density, into a metric function of penetration thickness (or some other parameter) on a moving spacecraft at some particular distance from the earth.

Summary of the AIAA/NASA/DOD Orbital Debris Conference - Technical issues and future directions
TL;DR: An international conference on orbital debris was held on April 16-19, 1990, in Baltimore, Maryland as mentioned in this paper, which included the implications of orbital debris for space flight, orbital debris measurements, modeling of the orbital debris environment, and methods to reduce the growth of the satellite's orbital debris population.
