The global space industry is growing rapidly, with an increasing number of annual rocket
launches. Gases and particulates are emitted by rockets directly into the middle and upper …

Atmospheric density modeling and uncertainty quantification for fast and accurate orbit
propagation are vital to drag force estimation for satellite reentry prediction and conjunction …

This study proposes a method for calculating the landing footprints of re-entry vehicles
based on the three-dimensional acceleration profile. Unlike the traditional case in which the …

The rate of rocket launches is accelerating, driven by the rapid global development of the
space industry. Rocket launches emit chemically and radiatively active species into the …

The re-entry trajectory optimization and the footprint determination for constrained vehicle
are important and challenging. This paper presents genetic algorithm (GA)-based …

This paper proposes a procedure for managing the risk of reentering space objects and risk
assessment methodologies used for the process. The proposed procedure comprises three …

Abstract Space debris are an urgent threat that is being strongly addressed by space
agencies worldwide. At present, the aerodynamic coefficients used in their re-entry …
