Making waves in space

Tuesday, September 15, 2020 - 10:41 in Physics & Chemistry

Image: The International Space Station is an exciting place for experiments. This one in particular was making waves in space. Called Fluidics, the experiment studies fluid dynamics in microgravity and recently performed another successful round of science on board the Space Station. Developed by French space agency CNES and co-funded by Airbus Defense and Space, the Fluidics or Fluid Dynamics in Space experiment is probing how fluids behave in weightlessness.Have you ever tried walking while carrying a full cup of water? Your steps invariably cause the water to slosh about, making spills hard to avoid. Now imagine a satellite turning – the fuel inside will slosh, affecting the satellite’s stability.  The experiment will help improve the performance of satellite propellant systems, extending their working lives by using every last drop in their tanks.A second part of the Fluidics experiment will look at capillary wave turbulence in liquids. On Earth, gravity and surface tension...
