All three approaches provide angles to the overarching goals of this project:<\/p>\n

Knowledge from terrestrial sites\/samples helps refine our experimental protocols<\/p>\n

Knowledge of Mars HySi sites helps selecting the most relevant sampling sites on Earth and compounds to experiment on in the lab<\/p>\n

In turn, knowledge from analogue field sites and experiments on HySi and organic matter helps better interpret what Mars HySi sites can tell us about the early water-bearing environments there.<\/p>\n

They also will help us pinpoint which sites should be explored in priority for their potential to host organic matter of astrobiological relevance\n
