Mudstone for silt (63 μm). On December 13, 2016, NASA reported further evidence supporting habitability on the planet Mars as the "Curiosity" rover climbed higher, studying younger layers, on Mount Sharp. Also reported, the very soluble element boron was detected for the first time on Mars. In June 2018, NASA reported that "Curiosity" had detected kerogen and other complex organic compounds from mudstone rocks approximately 3.5 billion years old. Mudstone Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Grain size is up to with individual grains too small to be distinguished without
NASA Earth Science NASA Earth Science NASA Earth Science, formerly called the NASA Earth Science Enterprise (ESE), formerly called Mission To Planet Earth (MTPE), is a NASA research program "to develop a scientific understanding of the Earth system and its response to natural and human-induced changes to enable improved prediction of climate, weather, and natural hazards for present and future generations". "To improve life here" and "To understand and protect our home planet," NASA supports research in the Earth Sciences and, as part of its Earth Observing System (EOS), launches and maintains Earth observing satellites to monitor the state of the climate, atmospheric
