Principles,Current Status and Prospects of Hydrated Minerals Detection on Mars with Hyperspectral Remote Sensing
摘要
Abstract
Mars is the most Earth-like terrestrial planet in the solar system and a primary focus of deep space exploration.Hydrated minerals,formed through water-rock interactions,are crucial for un-derstanding the planet's ancient aqueous environments,geological changes,and capacity to support life.Their study offers vital insights into Mars'climatic evolution and surface processes.Hyperspectral re-mote sensing,which collects detailed spectral data across hundreds of continuous bands,serves as a pow-erful tool for detecting and analyzing these minerals.Despite its advantages,hyperspectral detection on Mars faces significant challenges.The sparse distribution and low abundance of hydrated minerals,com-bined with spectral mixing and noise,diminish the clarity of diagnostic spectral features.Consequently,traditional methods primarily rely on spectral parameter mapping and visual interpretation,which are labor-intensive and struggle to process the vast hyperspectral datasets effectively.Recent advances in machine learning for terrestrial hyperspectral remote sensing offer innovative approaches to Martian min-eral mapping,yet their application remains at an early stage.This review first introduces Mars orbital spectral datasets such as the Observatoire pour la Minéralogie,l'Eau,les Glaces et l'Activité(OMEGA)and the Compact Reconnaissance Imaging Spectrometer for Mars(CRISM),and diagnostic spectral fea-tures of common hydrated minerals.The current state of Martian hydrated mineral detection is then ex-plored,covering both qualitative identification and quantitative abundance retrieval methods.It evalu-ates the advantages and limitations of existing approaches and highlights key challenges,such as spec-tral variability and validation constraints.To advance this field,future work should focus on developing adaptable algorithms,integrating multi-source data,and establishing robust validation frameworks.These efforts will enhance the efficiency and reliability of mineral mapping,providing deeper insights in-to Mars'aqueous history and its implications for planetary habitability.关键词
