United States Microgravity Payload-4 (USMP-4) experiments are prepared to be flown on Space Shuttle mission STS-87 in the Space Station Processing Facility at Kennedy Space Center (KSC). The vertical tube in the center of the photo is the Advanced Automated Directional Solidification Furnace (AADSF), which will be used by researchers to study the solidification of semiconductor materials in microgravity. Scientists will be able to better understand how microgravity influences the solidification process of these materials and develop better methods for controlling that process during future Space flights and Earth-based production. To its left is MEPHISTO, the French acronym for a cooperative American-French investigation of the fundamentals of crystal growth. All STS-87 experiments are scheduled for launch on Nov. 19 from KSC
