Abstract

To increase the knowledge about microbe-mineral interactions in space and the potential for in situ resource utilization (ISRU), and in preparation of the ESA BioRock space flight experiment, the interaction of the bacterium Cupriavidus metallidurans CH34 with basalt, a volcanic moon-analog rock, was investigated. The bacterial presence on basalt and its impact on weathering, as well as the effect of basalt mineralogy on nutrient leaching was studied. In addition, survival and the potential impact of space environmental conditions such as microgravity on these interactions were determined.
