Mars analog stations investigate lichen biodiversity during simulated missions

Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. They are known from every continent, and almost certainly every land mass on planet Earth; some species have even survived exposure to the exterior of the International Space Station. Once you know where to look for them, lichens are everywhere.
