Dynamic Surf (IMAGE) NASA/Johnson Space Center Caption The Japan Aerospace Exploration Agency's (JAXA) Dynamic Surf investigation is looking in to a phenomenon called Marangoni convection -- one of the fundamental principles of liquid motion which is revealed much more clearly in microgravity. Understanding the physics of this convection will improve research in crystals used for semiconductors and optics, and in DNA examination on the space station and on Earth.
