Adversarial Reinforcement Learning for Robust Planetary Landing
Miguel Leiva-Vélez, Nicolas Gaston-Rozado, Andrea Scorsoglio +3
Deep reinforcement learning (DRL) policies for planetary landing and other aerospace guidance, navigation, and control tasks are commonly trained under randomized disturbances to i…
VISTA: An Attention-Based Multi-Agent Reinforcement Learning Architecture for Space Situational Awareness Sensor Tasking
Miguel Leiva-Vélez, Adalberto Claudio Quiros, Nicolas Gaston Rozado +2
The rapid growth of resident space objects is increasing the complexity of space situational awareness sensor tasking, challenging classical optimization methods as they allocate f…
DreamSat: Towards a General 3D Model for Novel View Synthesis of Space Objects
Nidhi Mathihalli, Audrey Wei, Giovanni Lavezzi +4
Novel view synthesis (NVS) enables to generate new images of a scene or convert a set of 2D images into a comprehensive 3D model. In the context of Space Domain Awareness, since sp…
Self-supervised Machine Learning Based Approach to Orbit Modelling Applied to Space Traffic Management
Emma Stevenson, Victor Rodriguez-Fernandez, Hodei Urrutxua +2
This paper presents a novel methodology for improving the performance of machine learning based space traffic management tasks through the use of a pre-trained orbit model. Taking…
Orbital stability of compact three-planet systems, II: Post-instability impact behaviour
Peter Bartram, Alexander Wittig, Jack J. Lissauer +2
Recent observational missions have uncovered a significant number of compact multi-exoplanet systems. The tight orbital spacing of these systems has led to much effort being applie…
Earth's Minimoons: Opportunities for Science and Technology
Robert Jedicke, Bryce T. Bolin, William F. Bottke +5
(modified from published version) Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter astero…
Stability and chaos in Kustaanheimo-Stiefel space induced by the Hopf fibration
Javier Roa, Hodei Urrutxua, Jesús Peláez
The need for the extra dimension in Kustaanheimo-Stiefel (KS) regularization is explained by the topology of the Hopf fibration, which defines the geometry and structure of KS spac…
