S91-47323 (18 Sept 1991) --- Constantine Costes, left, a student experimenter sponsored by United Space Boosters Inc, in Huntsville, Alabama, discusses his student experiment, "Zero-G Rise of Liquid Through Porous Media" with astronauts Ronald J. Grabe (right), STS 42 mission commander; and William Readdy, mission specialist. The student experimenter and crew members are in the Full Fuselage Trainer (FFT) in the Shuttle Mockup and Integration Laboratory. While attending Randolph School, a high school in Huntsville, Alabama, Costes was chosen in the national competition to participate in the Shuttle Student Involvement Program (SSIP). The experiment, contained in a middeck locker, involves the investigation of the effects of gravity on the flow characteristics of a fluid. Both pure capillary and forced flow behavior will be investigated. A ground based experiment was conducted so that gravity influenced data can be compared to that gathered in weightlessness. Costes is now a candidate for a Ph.D in mathematics at Harvard University.
