Null string holography in AdS from local BRST descent
Sarthak Duary, Sourav Maji
We show that the radial sector of a Carroll-Weyl gauged null string in Poincaré is locally trivial in BRST cohomology. In a quotient-adapted BFV basis, the radial…
Transformer-Informed Trajectory Optimization for Relative Motion in Cislunar Orbits
Walter J. Manuel, Yuji Takubo, Simone D'Amico
Autonomous spacecraft guidance and control requires a fast solution to non-convex trajectory optimization, which can be accelerated by providing a near-optimal initial guess to an…
Stellar Observation Scheduling Optimization for Distributed Space Interferometry Missions
Ethan Foss, Antonio Rizza, Simone D'Amico
Growing interest in space interferometry for detecting bio-signatures of exoplanets has led to the development of several low-cost mission concepts involving Earth-orbiting formati…
Efficient Input-Constrained Impulsive Optimal Control of Linear Systems with Application to Spacecraft Relative Motion
Ethan Foss, Simone D'Amico
This work presents a novel algorithm for impulsive optimal control of linear time-varying systems with the inclusion of input magnitude constraints. Impulsive optimal control probl…
Optimal Impulsive Control of Cislunar Relative Motion using Reachable Set Theory
Matthew Hunter, Walter J. Manuel, Simone D'Amico
This work presents the first application of the state-of-the-art Koenig-D'Amico reachable set theory solver to cislunar, chaotic relative motion in the Circular-Restricted Three-Bo…
Long-Duration Station-Keeping Strategy for Cislunar Spacecraft Formations
Ethan Foss, Yuji Takubo, Simone D'Amico
This paper demonstrates a novel guidance and control strategy for cislunar near-rectilinear halo orbit formation-keeping applied to high-fidelity dynamics. Bounded relative motion…
Safe and Optimal N-Spacecraft Swarm Reconfiguration in Non-Keplerian Cislunar Orbits
Yuji Takubo, Walter Manuel, Ethan Foss +1
This paper presents a novel fuel-optimal guidance and control methodology for spacecraft swarm reconfiguration in Restricted Multi-Body Problems (RMBPs) with a guarantee of passive…
