Solidification is the process of freezing materials. The Advanced Automated Directional Solidification Furnace (AADSF) was a sophisticated materials science facility used for studying a common method of processing semiconductor crystals called directional solidification. The Spartan Auxiliary Mounting Plate (SPAM) was a small equipment mounting plate that provided a mounting location for small experiments or auxiliary equipment of the Spartan Flight Support Structure (SFSS) It was a honeycomb plate using an experimental silicon carbide aluminum face sheet material with an aluminum core.Īdvanced Automated Directional Solidification Furnace The Video Guidance Sensor (VGS) Flight Experiment was a laser guidance system that tested a key component of the Automated Rendezvous and Capture (AR&C) system. This link was used to provide a fine-pointing adjustment to the WLC based on solar images downlinked in real-time. The Technology Experiment Augmenting Spartan (TEXAS) was a Radio Frequency (RF) communications experiment that provided flight experience for components baselined on future Spartan missions, and a real-time communications and control link with the primary Spartan 201 experiments. Spartan 201 had three secondary experiments. Two primary experiments were the Ultraviolet Coronal Spectrometer from the Smithsonian Astrophysical Observatory and the White Light Coronograph (WLC) from the High Altitude Observatory. The objective of the observations was to investigate the mechanisms causing the heating of the solar corona and the acceleration of the solar wind that originates in the corona. It was expected to be deployed on orbit 18 and retrieved on orbit 52. Spartan 201-04 was a Solar Physics Spacecraft designed to perform remote sensing of the hot outer layers of the sun's atmosphere or solar corona. The extended mission capability offered by the Extended Duration Orbiter (EDO) kit provides an opportunity for additional science gathering time. The complement of microgravity research experiments was divided between two Mission-Peculiar Experiment Support Structures (MPESS) in the payload bay. The United States Microgravity Payload (USMP-4) was a Spacelab project managed by Marshall Space Flight Center, Huntsville, Alabama. STS-87 in-flight crew portrait United States Microgravity Payload Mid-deck experiments included the Middeck Glovebox Payload (MGBX) and the Collaborative Ukrainian Experiment (CUE). STS-87 flew the United States Microgravity Payload (USMP-4), Spartan-201, Orbital Acceleration Research Experiment (OARE), TEVA Demonstration Flight Test 5 (EDFT-05), the Shuttle Ozone Limb Sending Experiment (SOLSE), the Loop Heat Pipe (LHP), the Sodium Sulfur Battery Experiment (NaSBE), the Turbulent GAS Jet Diffusion (G-744) experiment, and the Autonomous EVA Robotic Camera/Sprint ( AERCam Sprint) experiment. It also marked the first EVA conducted by a Japanese astronaut, Takao Doi. An EVA from Columbia was originally planned for STS-5 in 1982 but was canceled due to spacesuit problems. This mission marked the first time an EVA was performed from Columbia. The mission goals were to conduct experiments using the United States Microgravity Payload (USMP-4), conduct two EVAs, and deploy the SPARTAN-201 experiment. It was the 88th flight of the Space Shuttle and the 24th flight of Columbia. STS-87 was a Space Shuttle mission launched from Launch Complex 39B of the Kennedy Space Center on 19 November 1997.
