N2 - Understanding the deformation mechanisms and mechanical properties of asteroids that are Near-Earth Objects is crucial in developing hazard mitigation strategies, as well as unraveling their potential engineering applications. A comprehensive study of the microstructure and mechanical behavior of Viñales (L6) ordinary chondrite is conducted. First, elastic wave velocity measurements are conducted to determine the mechanical properties and the material symmetry of Viñales. Next, optical microscopy is applied for microstructure characterization to identify the primary mineral phases and corresponding texture. Additionally, the composition of each mineral is determined using a scanning electron microscope equipped with wavelength-dispersive spectrometers, where an X-ray intensity map is plotted for ordinary chondrites elements of interest. The Brunauer–Emmett–Teller (BET) method is used to measure the average pore surface area and adsorption pore volume. Finally, quasi-static compression tests, accompanied with in-situ digital image correlation are utilized to investigate the failure type as well as localizing the regions of excessive deformation and failure.
