Our country's research team uncovers salt weathering phenomena on Mars

The surface layer of Martian rocks is a key carrier that records atmospheric–surface interactions, but the scientific community still lacks a full understanding of the mechanisms behind the formation of their surface textures. Recently, a research team from units including the National Space Science Center of the Chinese Academy of Sciences identified, based on in-situ observation data from China’s Tianwen-1 Mars rover Zhurong, near-parallel lamellar spalling on the surface of Martian rocks, broken fragments that interlock with one another, and densely distributed pits. These morphological features are similar to salt-weathering products on Earth. The study was published recently in the academic journal Science Bulletin. (CCTV News)
