Optimization of Asteroid Capture Missions Using Earth Resonant Encounters here modelled by means of a Keplerian Map approximation, and these are a posteriori compared with the dynamics of the Circular Restricted Three-Body Problem. Savings in the order of 50% of total . are computed for four different asteroids.

A Parametric Study of the Orbital Lifetime of Super GTO and SSTO Orbits Based on Semi-analytical Intid to the needs of space surveillance and tracking (SST). The time histories of selected trajectories suggest that the smaller lifetimes are related to resonances of the Kozai type, thus enlarging the scope of the time-reentry maps, which can be used as a general tool to study the dynamics of highly elliptic orbits.

Active Debris Removal and Space Debris Mitigation using Hybrid Propulsion Solutionsbit propulsion systems, in terms of complexity, cost, operational advantages, whilst also offering the use of non-toxic propellants. The study has been carried out by Elecnor Deimos, expert in mission analysis, and Nammo Raufoss, expert in hybrid propulsion.

Development of a Debris Indexof the index is known for any point in the grid, a simple interpolation can be used to compute the value of the index for any object. The current work aims to extend a previous formulation, which focussed only on the effect of collisions, by including also the effect of explosions and considering the likelihood of these fragmentations.

Taxonomy of LEO Space Debris Population for ADR Capture Methods SelectionDR association is refined. Examples of application of the developed taxonomy are presented at the end of the paper and conclusions are drawn regarding the best methods to be used for the main categories of LEO space debris under investigation for future ADR missions.
