STS062-52-025 (4-18 March 1994) --- Astronaut Pierre J. Thuot, mission specialist, works with the Middeck 0-Gravity Dynamics Experiment (MODE) aboard the earth-orbiting Space Shuttle Columbia. The reusable test facility is designed to study the nonlinear, gravity-dependent behavior of two types of space hardware -- contained fluids and (as depicted here) large space structures -- planned for future spacecraft.
