This project involved a field campaign in the Atacama Desert of northern Chile, combining UAV-based mapping with geological fieldwork and laboratory analysis. The fieldwork focused on collecting geological samples and documenting surface conditions in the hyper-arid desert environment. I participated in systematic sampling at selected locations and used drilling equipment and other field tools to collect material from different surface and subsurface settings. GNSS measurements and field observations were used to document the locations and geological context of the collected samples. After the field campaign, I worked with the samples in a sediment laboratory and prepared them for further investigation. Sample preparation included processes such as leaching and sieving to separate and concentrate different material fractions. The prepared samples were then systematically examined under a stereomicroscope to identify particles with characteristics potentially consistent with micrometeorites. Selected particles were further investigated using scanning electron microscopy (SEM) to examine their morphology, surface characteristics, and composition and to support their characterization. This required distinguishing potential extraterrestrial particles from the diverse terrestrial materials present in the samples. Through this process, I became familiar with the appearance and characteristics of different terrestrial minerals, sediments, and particles encountered during microscopic analysis. The project gave me practical experience across the complete workflow from field sampling and sample documentation to sediment preparation, microscopy, and material characterization. Combining field observations, remote sensing, and laboratory analysis also strengthened my ability to connect large-scale surface processes with material-level observations.
