Exoplanetary Tour Design with Solar Sails: TheAntipodes Results in the GTOC13 Problem
Jack Yarndley, Adam Evans, Xingyu Zhou +2
The paper describes the solution developed by team TheAntipodes for the GTOC13 challenge, using a combination of beam search, resonant targeting, and sequential convex programming…
Distribution-Agnostic Robust Trajectory Optimization via Chance-Constrained Reinforcement Learning
Yashdeep Chaudhary, Roberto Armellin, Harry Holt +1
This paper presents a distribution-agnostic robust trajectory-optimization framework based on chance-constrained reinforcement learning. The uncertainty is represented here through…
Time-Optimal Collision Avoidance Via a Greedy Polynomial Backward Sweep
Zeno Pavanello, Frank De Veld, Roberto Armellin
Spacecraft collision avoidance for low-thrust satellites often requires determining not only how to maneuver, but also how late a maneuver can begin while still ensuring safety. Th…
Tiny Recursive Models for Solving the J2-Perturbed Lambert Problem
Minduli Wijayatunga, Roberto Armellin
This paper presents a fast, recursive neural solver for the J2-perturbed Lambert problem based on Tiny Recursive Models (TRM), termed the TRM-Perturbed Lambert (TRM-PL) model. TRM…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario JuriÄ +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
Sample-Free Safety Assessment of Neural Network Controllers via Taylor Methods
Adam Evans, Roberto Armellin
In recent years, artificial neural networks have been increasingly studied as feedback controllers for guidance problems. While effective in complex scenarios, they lack the verifi…
