Efficient trajectory design for distant planetary orbiters
Francesca Scala, Ioannis Gkolias, Camilla Colombo
Starting from the Hamiltonian representation of the dynamics in \cite{rosengren2015chaos,colombo2019long}, this work proposes an innovative procedure to design fully-analytical man…
Ejecta cloud distributions for the statistical analysis of impact cratering events onto asteroids' surfaces: a sensitivity analysis
Mirko Trisolini, Camilla Colombo, Yuichi Tsuda
This work presents the model of an ejecta cloud distribution to characterise the plume generated by the impact of a projectile onto asteroids surfaces. A continuum distribution bas…
Target selection for Near-Earth Asteroids in-orbit sample collection missions
Mirko Trisolini, Camilla Colombo, Yuichi Tsuda
This work presents a mission concept for in-orbit particle collection for sampling and exploration missions towards Near-Earth asteroids. Ejecta is generated via a small kinetic im…
Interface between the long-term propagation and the destructive re-entry phases exploiting the overshoot boundary
Christian Fusaro, Mirko Trisolini, Camilla Colombo
In recent years, due to the constant increase of the density of satellites in the space environment, several studies have been focused on the development of active and passive stra…
Re-entry prediction and demisability analysis for the atmospheric disposal of geosynchronous satellites
Mirko Trisolini, Camilla Colombo
The paper presents a re-entry analysis of Geosynchronous Orbit (GSO) satellites on disposal trajectories that enhance the effects of the Earth oblateness and lunisolar perturbation…
Fragmentation model and strewn field estimation for meteoroids entry
Simone Limonta, Mirko Trisolini, Stefan Frey +1
Everyday thousands of meteoroids enter the Earth's atmosphere. The vast majority burn up harmlessly during the descent, but the larger objects survive, occasionally experiencing in…
Dynamical taxonomy of the coupled solar radiation pressure and oblateness problem and analytical deorbiting configurations
Ioannis Gkolias, Elisa Maria Alessi, Camilla Colombo
Recent works demonstrated that the dynamics caused by the planetary oblateness coupled with the solar radiation pressure can be described through a model based on singly-averaged e…
Impact probability computation of Near-Earth Objects using Monte Carlo Line Sampling and Subset Simulation
Matteo Romano, Matteo Losacco, Camilla Colombo +1
This work introduces two Monte Carlo (MC)-based sampling methods, known as line sampling and subset simulation, to improve the performance of standard MC analyses in the context of…
Stable attitude dynamics of planar helio-stable and drag-stable sails
Narcís Miguel, Camilla Colombo
In this paper the planar orbit and attitude dynamics of an uncontrolled spacecraft is studied, taking on-board a deorbiting device. Solar and drag sails with the same shape are con…
Extension of the King-Hele orbit contraction method for accurate, semi-analytical propagation of non-circular orbits
Stefan Frey, Camilla Colombo, Stijn Lemmens
Numerical integration of orbit trajectories for a large number of initial conditions and for long time spans is computationally expensive. Semi-analytical methods were developed to…
Towards a sustainable exploitation of the geosynchronous orbital region
Ioannis Gkolias, Camilla Colombo
In this work the orbital dynamics of Earth satellites about the geosynchronous altitude are explored, with primary goal to assess current mitigation guidelines as well as to discus…
Phase space description of the dynamics due to the coupled effect of the planetary oblateness and the solar radiation pressure perturbations
Elisa Maria Alessi, Camilla Colombo, Alessandro Rossi
The aim of this work is to provide an analytical model to characterize the equilibrium points and the phase space associated with the singly-averaged dynamics caused by the planeta…
