Degradation of microbial fluorescence biosignatures by solar ultraviolet radiation on Mars [PDF]

, 2014
Recent and proposed robotic missions to Mars are equipped with implements to expose or excavate fresh material from beneath the immediate surface. Once brought into the open, any organic molecules or potential biosignatures of present or past life will ...

An astrobiological perspective on microbial biofilms: their importance for habitability and production of detectable and lasting biosignatures

Applied and Environmental Microbiology
The search for life elsewhere in the universe has remained one of the main goals of astrobiological exploration. In this quest, extreme environments on Earth have served as analogs to study the potential habitability of Mars and icy moons, which include ...
