    The Coarsening in Solid-Liquid Mixtures-2 (CSLM-2) Experiment was launched on the Space Shuttle Endeavour for operations onboard the International Space Station.

    9/11/2007

    At 6:36 p.m. EDT on Wednesday, August 8, the Coarsening in Solid-Liquid Mixtures-2 (CSLM-2) Experiment was launched on the Space Shuttle Endeavour for operations onboard the International Space Station in February, 2008. The experiment was designed and built according to the stringent requirements required of space flight hardware by ZIN Technologies Inc under contract with the NASA Glenn Research Center in Cleveland, Ohio.

    The CSLM-2 Experiment consists of an Electronics Control Unit (ECU), Sample Processing Unit (SPU) and associated cables and mounting hardware. The CSLM-2 experiment will be installed in the Microgravity Science Glovebox (MSG) to process the 5 Sample Processing Units (SPU). The SPU is an evacuated thermal chamber which will heat the samples to 185 ºC for a specified duration. At the conclusion of the heat soak time the samples will be quenched utilizing a pressurized water reservoir. The ECU is a microprocessor based data acquisition and control system designed specifically for conducting the CSLM-2 experiment. The CSLM-2 hardware interfaces to the MSG power, communications, and vacuum resources in support of experiment operations.

    Data gathered by the CSLM-2 experiment will advance the development of new high-temperature materials, such as those used in nuclear propulsion and waste heat coolant processes by investigating the kinetics of competitive particle growth within a liquid matrix. During this process, called coarsening, small particles shrink by losing atoms to larger particles causing the larger particles to grow or coarsen. The science team is headed by Professor Peter Voorhees of the Department of Materials Science and Engineering at Northwest University.
