Sapphire Mineral Detected on Mars
In 2025, the Perseverance rover discovered the mineral corundum bearing traces of chromium on the surface of Mars for the first time in a Martian environment. This discovery followed the analysis of three rock samples using spectroscopic techniques, which revealed that these rocks contain corundum and plagioclase, raising questions about the conditions under which they formed. It is believed that intense impacts and the presence of hot liquids contributed to the formation of the mineral, supporting the hypothesis that geological processes and thermal changes occurred in the region. Although microscopic grains of corundum are found within the rocks, there is no evidence of a large sapphire on the surface. Researchers hope to collect additional samples to uncover more secrets about the mineral’s formation and the previous conditions on Mars.
