These samples will permit researchers to gain a better understanding of their crystalline structures. Such information may lead to improved medicines such as insulin for the treatment of diabetes. In another series of materials-science experiments, crew members activated an experiment that automatically mixed hundreds of chemical samples. Experiment sponsors hoped to demonstrate technology for making microgravity research more affordable to scientists and small companies. In further research supporting the development of Space Station Freedom, crew members conducted experiments on a redesigned manifold element for the Space Station Heat Pipe Advanced Radiator Element.
Heat pipes are extremely efficient heat transfer devices.
Although bubbles did form at the manifold, they could be dislodged by vigorous tapping of the apparatus. This experiment was sponsored by NASA's Office of Space Flight. In preparation for the STS-37 mission, all five crew members had qualified for amateur radio licenses. Hundreds of radio contacts were made between the crew and ham radio operators around the world. Several schools across the United States also participated in the experiment, and students were able to question STS- 37 crew members directly about their mission.
