Abstract
High-Ti deposits on the Moon may emerge as a key resource for oxygen extraction. Descriptive models are the first qualitative step toward quantitative assessments of natural resources. Such models provide a structured framework for understanding the formation processes and spatial distribution of discrete types of resource deposits. In this study, we provide the first lunar descriptive models, characterizing high-Ti lunar deposits, drawing parallels with established models used in assessing mineral deposits on Earth.
Our methodology involves utilizing remote sensing datasets and geological maps to identify and describe high-Ti deposits. This is supplemented by data extrapolated from Apollo missions. However, there remain critical knowledge gaps, particularly regarding petrography, subsurface information, surface characteristics, and physical properties of high-Ti deposits, which necessitate further exploration and analysis.
期刊介绍：
Acta Astronautica is sponsored by the International Academy of Astronautics. Content is based on original contributions in all fields of basic, engineering, life and social space sciences and of space technology related to:
The peaceful scientific exploration of space,
Its exploitation for human welfare and progress,
Conception, design, development and operation of space-borne and Earth-based systems,
In addition to regular issues, the journal publishes selected proceedings of the annual International Astronautical Congress (IAC), transactions of the IAA and special issues on topics of current interest, such as microgravity, space station technology, geostationary orbits, and space economics. Other subject areas include satellite technology, space transportation and communications, space energy, power and propulsion, astrodynamics, extraterrestrial intelligence and Earth observations.
