Watching a bubble float effortlessly through the International Space Station may be mesmerizing and beautiful to witness, but that same bubble is also teaching researchers about how fluids behave differently in microgravity than they do on Earth. The near-weightless conditions aboard the station allow researchers to observe and control a wide variety of fluids in ways that are not possible on Earth, primarily due to surface tension dynamics and the lack of buoyancy and sedimentation within fluids in the low-gravity environment. Understanding how fluids react in these conditions could lead to improved designs on fuel tanks, water systems and other fluid-based systems for space travel, as well as back on Earth.

During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman — along with European Space Agency astronaut Alexander Gerst — explored the phenomenon of water surface tension in microgravity on the International Space Station.
