Experiments. Astronauts Catherine G. Coleman (left) and Fred W. Leslie working in the United States Microgravity Laboratory (USML-2) on the Space Shuttle Columbia during Mission STS-73. Coleman, a mission specialist, uses a glovebox whilst Leslie, a payload specialist from the private sector, is monitoring the Surface-Tension- Driven Convection Experiment (STDCE). USML-2 was used for research into fluid physics, materials science, biotechnology, combustion science and commercial space processing techniques. The crew of seven worked in two separate shifts to maximize the use of the laboratory during the mission, which lasted from 20 October to 5 November 1995.
