In this episode we delve into the crucial role of water in lunar and space exploration, discussing water processing and purification strategies. Our guests, Giorgio Boscheri, a Space Engineer from Thales Alenia Space Italia, and Anna Jurga and Karol Leluk, researchers from the Faculty of Environmental Engineering at Wrocław University of Science and Technology, bring diverse perspectives to the discussion. We explore the significance of environmental engineering in space system design, emphasizing water's importance and the challenges of purifying lunar-extracted water. Topics include lunar water purification methods, tailored technologies for spacecraft environments, and the potential for in-situ agriculture on the Moon.
