NASA Bucket Drum Challenge

Equipped with a gravity scoop cover, the valve can only be opened by gravity itself. Based on observation alone, it's estimated that 70-80% of the materials could be made from this design, if the assumption holds true. LOADING: When the first load is scooped up, the cover will open due to the sheer volume of material going in. As the first scoop rises, the next scoop cover remains closed due to the weight of the material inside it, meaning that the second scoop won't be unloaded until there's no material obstructing its cover - when it reaches open air. The material on the scoop will push the cover open by gravity. UNLOADING: During transport, the drum will remain in a halted state to conserve battery power. The regolith won't fall due to the cover blocking the scoop opening. Unloading will occur in reverse, with the regolith pushing the cover (featuring a small bend at the end) to open it up. The 60-degree opening is just enough for the regolith to slide out of the scoop. SCOO: The scoop features an anti-clog surface that prevents Regolith from sticking to its surface. SCOO COVER: Made from checkered plate, the irregular surface helps with the flow of Regolith. This removable scoop was designed to withstand wear and tear on the original scoop.
