The Regolith Drum boasts two distinct compartments, each equipped with a spiral scoop positioned at an angle of precisely 35 degrees apart. This innovative design enables the drum to achieve its maximum fill ratio with minimal regolith loss during rotation. The result is a highly efficient collection process. Manufacturing The entire drum assembly is crafted from high-quality titanium sheet metal, providing a lightweight yet robust structure that can withstand the rigors of long-term use. In comparison, aluminum and carbon fiber alternatives would falter under similar conditions. To ensure maximum strength and stability, all components are carefully welded at strategic alignment tabs. Technical Specifications Material: Ti 6Al 4V Weight: 2.6 kg Drum Length: 348 mm Drum Diameter: 450 mm Engaged Scoop Width: 172 mm Maximum Regolith Capacity: 33 liters
