Microorganisms
Microorganisms are living organisms that are too small to be seen with the naked eye. They include bacteria, viruses, fungi, protozoa, and algae. In the context of space and astronautical engineering, microorganisms play an important role in the study of astrobiology, which is the study of the origin, evolution, distribution, and future of life in the universe. Microorganisms are used in space research to study the effects of microgravity and radiation on living organisms, to develop life support systems for long-duration space missions, and to test the efficacy of antimicrobial agents for use in space habitats. Microorganisms are also used in the production of food, fuel, and other materials in space. However, microorganisms can also pose a risk to human health in space, as they can cause infections and contaminate equipment and surfaces.
