Asteroid Mining: ACT&Friends' Results for the GTOC 12 Problem
Dario Izzo, Marcus Märtens, Laurent Beauregard +8
In 2023, the 12th edition of Global Trajectory Competition was organised around the problem referred to as "Sustainable Asteroid Mining". This paper reports the developments that l…
Certifying Guidance & Control Networks: Uncertainty Propagation to an Event Manifold
Sebastien Origer, Dario Izzo, Giacomo Acciarini +4
We perform uncertainty propagation on an event manifold for Guidance & Control Networks (G&CNETs), aiming to enhance the certification tools for neural networks in this field. This…
EclipseNETs: a differentiable description of irregular eclipse conditions
Giacomo Acciarini, Francesco Biscani, Dario Izzo
In the field of spaceflight mechanics and astrodynamics, determining eclipse regions is a frequent and critical challenge. This determination impacts various factors, including the…
Nonlinear Propagation of Non-Gaussian Uncertainties
Giacomo Acciarini, Nicola Baresi, David Lloyd +1
This paper presents a novel approach for propagating uncertainties in dynamical systems building on high-order Taylor expansions of the flow and moment-generating functions (MGFs).…
NeuralODEs for VLEO simulations: Introducing thermoNET for Thermosphere Modeling
Dario Izzo, Giacomo Acciarini, Francesco Biscani
We introduce a novel neural architecture termed thermoNET, designed to represent thermospheric density in satellite orbital propagation using a reduced amount of differentiable com…
Computing low-thrust transfers in the asteroid belt, a comparison between astrodynamical manipulations and a machine learning approach
Giacomo Acciarini, Laurent Beauregard, Dario Izzo
Low-thrust trajectories play a crucial role in optimizing scientific output and cost efficiency in asteroid belt missions. Unlike high-thrust transfers, low-thrust trajectories req…
Global Optimization for Trajectory Design via Invariant Manifolds in the Earth-Moon Circular Restricted Three-Body Problem
Flavio Tagliaferri, Emmanuel Blazquez, Giacomo Acciarini +1
This study addresses optimal impulsive trajectory design within the Circular Restricted Three-Body Problem (CR3BP), presenting a global optimization-based approach to identify mini…
Stochastic Continuation of Trajectories in the Circular Restricted Three-Body Problem via Differential Algebra
Giacomo Acciarini, Nicola Baresi, David J. B. Lloyd +1
Numerical continuation techniques are powerful tools that have been extensively used to identify particular solutions of nonlinear dynamical systems and enable trajectory design in…
Breaking traditions: introducing a surrogate Primer Vector in non Keplerian dynamics
Laurent Beauregard, Dario Izzo, Giacomo Acciarini
In this study, we investigate trajectories involving multiple impulses within the framework of a generic spacecraft dynamics. Revisiting the age-old query of "How many impulses?",…
Closing the Gap Between SGP4 and High-Precision Propagation via Differentiable Programming
Giacomo Acciarini, Atılım Güneş Baydin, Dario Izzo
The Simplified General Perturbations 4 (SGP4) orbital propagation method is widely used for predicting the positions and velocities of Earth-orbiting objects rapidly and reliably.…
