As humans spread into the cosmos, we will take a plethora of initially Earth-bound life with us for the ride. Some might be more beneficial or potentially harmful than others. And there is no lifeform more prevalent on Earth than bacteria. These tiny creatures and fungi, their long-lost cousins on the evolutionary tree, have a habit of clumping together to form a type of structure known as a biofilm. Biofilms are ubiquitous in Earth-bound environments and have been noticed on space missions for decades. But what potential dangers do they pose? More interestingly, what possible problems can they solve? A paper from a group of scientists focused on life support systems in the journal Biofilm provides a high-level overview of the state of the science of understanding how biofilms work in space and where it might need to go for us to establish a permanent human presence off-world.
