Liquid Behavior in Space

Liquid behavior in space differs from Earth due to microgravity, where the force pushing objects downward is nearly absent. In this environment, liquids don't settle into a specific shape but form floating spheres or blobs, driven by surface tension—similar to water droplets on a surface. Without gravity, liquids can cling to surfaces, move unpredictably, and mix in unusual ways. Understanding this behavior is vital for designing spacecraft systems, fuel management, and experiments, ensuring liquids behave predictably and safely in the unique environment of space.
