The return to the Moon is an important short-term goal of NASA and other international space agencies. To minimize mission risks, technologies, such as rovers or regolith processing systems, must be developed and tested on Earth using lunar regolith

Large amounts of microorganisms are emitted from animal houses into the environment via exhaust air. To assess the potential risks, the spread of microorganisms can be simulated with computer models. Such modeling usually does not take into account d

The use of lunar hybrid rockets, that connect the Moon surface with a lunar gateway and provide it with resources, are evaluated. Therefore, the composition of lunar regolith and its use for specific rocket subsystems is assessed. In particular, this
