Lubricants are super important in space tech. They keep things moving smoothly. But how do they act when gravity changes? That's what this study looked into. Scientists used fancy computer models to see how different gravity levels affect a common space lube called PAO. They found some cool stuff. When gravity is low, the lube gets thicker and moves unevenly. This c...
