Positioning techniques using the effects of acoustic-radiation pressure were used during the Spacelab 3 flight to carry out classical fluid dynamics experiments on liquid drops freely suspended in microgravity. Quantitative results dealing with the equilibrium shapes of acoustically rotated drops, with the response to the radiation pressure forces, and finally with the experimental measurement of surface tension have been obtained.
In June of 1983, Dr. Wang was selected by NASA to train as an astronaut-scientist for Spacelab-3, a research facility flown in the cargo bay of the space shuttle. In 1985, Dr. Wang flew aboard the Challenger as part of a seven member crew on the successful STS-51B mission (April 29 - May 5). During the flight, Dr. Wang studied the dynamic behavior of rotating spheroids in zero gravity in an experimental facility which he designed called the Drop Dynamics Module (DDM).
