Mineralogical Identification of Traces of Lifeoviding clues to their biogenicity. However, ageing modifies these properties to some extent. Moreover, some abiotic processes form minerals with similar properties. Therefore, decoding traces of life in minerals requires caution, and one prerequisite is a reliable estimation of the geochemical cond

Role of Mineral Surfaces in Prebiotic Processes and Space-Like Conditionsfe on Earth or possibly on other planets. Mineral surfaces may act as adsorbents, templates and catalysts driving the abiotic evolution of chemical systems on early Earth and in space towards increasing molecular complexity. Investigations about molecule-mineral interactions provide also important s

Exoplanetary Biosignatures for Astrobiology. Life, for example, can impact weathering rates which, in turn, influence climate stabilizing feedback cycles on Earth. Photosynthesis is ultimately responsible for our oxygen-rich atmosphere, which favours the formation of the protective ozone layer. The recent rise of exoplanetary science has led

Searching for Signs of Life on Other Planets: Mars a Case Studyic scientific community expects the evidence to be convincing—for example, several independent lines of analyses performed on a feature where the results can only be explained by a biological process. (2) Most bodies are difficult to explore in situ, just about the only way to achieve the above goal
