Zothecula writes: NASA’s Curiosity Mars rover has completed its first soil analysis of the Red Planet. The unmanned explorer used an advanced, miniaturized X-ray diffraction instrument that is part of the Chemistry and Mineralogy instrument (CheMin) of its internal laboratory. The soil, collected at a site designated “Rocknest” in Gale Crater, reveals that Martian soil is a weathered volcanic type similar to soils found in the Hawaiian Islands. Link to Original Source
