The Maximum Initial Mass
Dario Izzo, Giacomo Acciarini
We introduce the maximum-initial-mass problem as a standalone optimal-control formulation for low-thrust trajectory design and analyze its structure within Pontryagin's framework.…
EclipseNETs: Learning Irregular Small Celestial Body Silhouettes
Giacomo Acciarini, Dario Izzo, Francesco Biscani
Accurately predicting eclipse events around irregular small bodies is crucial for spacecraft navigation, orbit determination, and spacecraft systems management. This paper introduc…
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…
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…
