ISS Science for Everyone

Science Objectives for Everyone
Biodegradation investigates the initial stages of the biodegrading and biodeterioration of surfaces of structural materials used in the ISS. These samples will help us understand what microorganisms are present on ISS and will help develop effective methods of protecting spacecraft surfaces such as new coatings and advanced biocides. The collected samples will be returned to Earth for detailed microbial analysis.
