Catalog and Characterization of Science Orbit Configurations for an Enceladus Orbiter
Spencer Boone, Joan Pau Sanchez Cuartialles, Stéphanie Lizy-Destrez
Saturn's moon Enceladus is an exciting destination for future exploration missions due to the scientifically interesting geyser region located on its South pole. In this work, we c…
Non-linear stochastic trajectory optimisation
Thomas Caleb, Roberto Armellin, Stéphanie Lizy-Destrez
Designing robust space trajectories in nonlinear dynamical environments, such as the Earth-Moon circular restricted three-body problem (CR3BP), poses significant challenges due to…
Optimization of Transfers linking Ballistic Captures to Earth-Moon Periodic Orbit Families
Lorenzo Anoè, Roberto Armellin, Jack Yarndley +2
The design of transfers to periodic orbits in the Earth-Moon system has regained prominence with NASA's Artemis and CNSA's Chang'e programs. This work addresses the problem of link…
Chance constraints transcription and failure risk estimation for stochastic trajectory optimisation
Thomas Caleb, Roberto Armellin, Stéphanie Lizy-Destrez
Stochastic trajectory optimisation under uncertainty requires robust constraint satisfaction through chance constraints. However, existing transcription methods remain limited to s…
Taylor polynomial-based constrained solver for fuel-optimal low-thrust trajectory optimisation
Thomas Caleb, Roberto Armellin, Spencer Boone +1
This paper presents differential algebra-based differential dynamic programming (DADDy), a publicly available C++ framework for constrained, fuel-optimal low-thrust trajectory opti…
