This lecture explores the challenges of granular matter in non-equilibrium physics and its applications in industrial processes and space exploration. Investigations in low and zero gravity are crucial for understanding granular gases, fluids, and solid packings. The talk addresses research pillars in microgravity, Lunar exploration, and applications on Earth, emphasizing the importance of utilizing resources found in space. The lecture also delves into the implications for building materials like concrete, which has a significant environmental impact due to CO2 emissions.
