TL;DR: To map out a coherent Ocean Worlds Program, significant input is required from studies here on Earth; rigorous Research and Analysis studies are called for to enable some future ocean worlds missions to be thoughtfully planned and undertaken.
Journal ArticleDOI
Hyperspectral Anomaly Detection Through Spectral Unmixing and Dictionary-Based Low-Rank Decomposition
TL;DR: This paper focuses on anomaly detection in hyperspectral images (HSIs) and proposes a novel detection algorithm based on spectral unmixing and dictionary-based low-rank decomposition, which achieves high detection rate while maintaining low false alarm rate regardless of the type of images tested.
Journal ArticleDOI
Geophysical investigations of habitability in ice-covered ocean worlds
Steven D. Vance,Mark P. Panning,Simon Stähler,Simon Stähler,Fabio Cammarano,Bruce G. Bills,Gabriel Tobie,Gabriel Tobie,Shunichi Kamata,Sharon Kedar,Christophe Sotin,William T. Pike,Ralph D. Lorenz,Hsin-Hua Huang,Hsin-Hua Huang,Jennifer M. Jackson,Bruce Banerdt +16 more
TL;DR: In this paper, the variability and correlation of these parameters using 1-D internal structure models were explored, and it was shown that combinations of geophysical parameters might be used to distinguish an oxidized ocean dominated by aqueous MgSO_4 from a more reduced ocean dominating by NaCl.
Proceedings ArticleDOI
Low-rank tensor decomposition based anomaly detection for hyperspectral imagery
TL;DR: A Low-rank Tensor Decomposition based anomaly Detection (LTDD) algorithm for Hyperspectral Imagery is proposed which adopts an unmixing approach to the reconstructed core tensor for anomaly detection.
Journal ArticleDOI
Geophysical tests for habitability in ice-covered ocean worlds

TL;DR: In this paper, the authors developed 1-D calculations of internal structure of Enceladus using available constraints on the thermodynamics of aqueous MgSO$_4$, NaCl (as seawater), and NH$_3$, water ices, and silicate content.
