Análises químicas da matéria orgânica presente em amostras lunares

Abstract

ArtigosChemical analysis of organic matter present in lunar samples -Primitive celestial bodies, particularly those containing ice, preserve information that goes back to the formation of the solar system. Hence, research on primitive celestial bodies is crucial to explain the origin and evolution of these bodies and the origin of life in our solar system. The permanently shaded regions (PSRs) of the Moon's polar ice preserve volatile and organic compounds that have been delivered by comets and/or asteroids. On the other hand, the lunar regolith contains organic compounds, but its origin was recently determined to be terrestrial contamination during the handling of samples returned by the Apollo space missions in the 1970s. The chemical analyses of the organic matter present in lunar samples shows the importance of the curation of primitive materials from our solar system.
