Throughout the week International Space Station Commander/Science Officer Leroy Chiao prepared the U.S. Destiny Laboratory for the arrival of additional science experiments. The next Russian Progress supply mission is expected at the Space Station Dec. 25. He helped with several tests of the Active Rack Isolation System in one of the payload racks that will be used to house investigations.

For the "Saturday Science" program, Chiao conducted the In-Space Soldering Investigation experiment. He soldered 18 test articles, while the activity was recorded by a camcorder. He performed an additional test on a debris containment system that keeps nontoxic debris, like solder, from floating loose in the Station.

The tests connect the coupons, metal alloy wires of various configurations, together with solder and are designed to evaluate the effectiveness of different geometries typical of the kinds of operations that might be required in the future. The ground team monitoring the work expressed high satisfaction with their preliminary review of the down linked live video, indicating all coupons should yield important science data when they are returned to Earth.

Chiao took photos of the Binary Colloidal Alloys Test. Researchers are using the experiment to study fluids like milk or paint that have particles suspended in them. The experiment samples are shaken initially and then photographed periodically to document how the particles settle in microgravity. Researchers hope to use this data to develop new technologies ranging from rocket propulsion to cable television.

NASA’s payload operations team at the Marshall Center coordinates science activities on Space Station.
