Exoplanetary Tour Design with Solar Sails: TheAntipodes Results in the GTOC13 Problem
Jack Yarndley, Adam Evans, Xingyu Zhou +2
Solar sails present an attractive but challenging propulsion method for large-scale, long-duration trajectory design problems. In 2025, the 13th Global Trajectory Optimization Comp…
Station-Keeping Approach for Extremely Low Lunar Orbits with Solar Sailing
Jack Yarndley, Gregory Lantoine, Roberto Armellin
Renewed interest in cislunar space has created opportunities for sustained operations in extremely low-lunar orbits (eLLOs), where altitudes below 50~km enable close surface proxim…
Can LLMs Do Rocket Science? Exploring the Limits of Complex Reasoning with GTOC 12
Iñaki del Campo, Pablo Cuervo, Victor Rodriguez-Fernandez +2
Large Language Models (LLMs) have demonstrated remarkable proficiency in code generation and general reasoning, yet their capacity for autonomous multi-stage planning in high-dimen…
Sequential Convex Programming for Multimode Spacecraft Trajectory Optimization
Jack Yarndley
Spacecraft equipped with multiple propulsion modes or systems can offer enhanced performance and mission flexibility compared with traditional configurations. Despite these benefit…
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…
Using the Translation Theorem for the Automated Stationkeeping of Extremely-Low Lunar Missions
Jack Yarndley, Martin Lara, Harry Holt +1
Extremely-Low Lunar Orbits (eLLOs) (altitudes km) exhibit severe perturbations due to the highly non-spherical lunar gravitational field, presenting unique challenges to…
GTOC 12: Results from TheAntipodes
Roberto Armellin, Andrea Bellome, Xiaoyu Fu +4
We present the solution approach developed by the team `TheAntipodes' during the 12th edition of the Global Trajectory Optimization Competition (GTOC 12). An overview of the approa…
Multi-Target Spacecraft Mission Design using Convex Optimization and Binary Integer Programming
Jack Yarndley, Harry Holt, Roberto Armellin
The optimal design of multi-target rendezvous and flyby missions is challenging due to the combination of traditional spacecraft trajectory optimization and high-dimensional combin…
Asymmetric Assembly of Lennard-Jones Janus Dimers
Sina Safaei, Caleb Todd, Jack Yarndley +2
Self-assembly of Janus (or `patchy') particles is dependent on the precise interaction between neighbouring particles. Here, the orientations of two amphiphilic Janus spheres withi…
