Organic geochemistry of in situ thermal-based analyses on Mars: the importance and influence of minerals
A high-priority goal for past, present and future missions to Mars is the search for evidence of
past or present life. Some of the most information-rich signals are those represented by …

Organic biosignature degradation in hydrothermal and serpentinizing environments: Implications for life detection on icy moons and Mars
Evidence of liquid water is a primary indicator of habitability on the icy moons in our outer
solar system as well as on terrestrial planets such as Mars. If liquid water-containing …

Experimental investigations of the preservation/degradation of microbial signatures in the presence of clay minerals under Martian subsurface conditions
The astrobiological exploration of Mars is ongoing. Ancient Martian terrains covered by clay
minerals are seen as the most promising targets to search for biosignatures as clay minerals …
