The STS-64 mission will carry the LIDAR In-Space Technology Experiment (LITE), a project to measure atmospheric parameters from a space platform utilizing laser sensors, the Robot Operated Materials ... Processing System (ROMPS) to investigate robot handling of thin film samples, and the Shuttle Pointed Autonomous Research Tool for Astronomy (SPARTAN-201). SPARTAN is a free-flying retrievable platform with two telescopes to study the solar wind, a continuous stream of electrons, heavy protons and heavy ions ejected from the sun and traveling through space at speeds of almost 1 million miles per hour. The solar wind frequently causes problems on Earth by disrupting navigation, communications and electrical power.
The STS-64 mission will also carry the Shuttle Plume Impingement Flight Experiment (SPIFEX). This experiment is designed to directly measure RCS plume loads in the far-field regime under actual on-orbit conditions. Discovery's payload bay also contains a GAS bridge assembly with 12 GAS canisters (G-178, G-254, G-312, G-325, G-417, G-453, G-454, G-456, G-485, G-506 and G-562). One additional experiment in the payload bay is the Trajectory Control Sensor (TCS) package positioned on an Adaptive Payload Carrier. It will provide relative trajectory data on a target vehicle operating in close proximity (less than 5000ft) of the Orbiter. The TCS will provide range and range rate data for target vehicles having a reflective surface. Additionally, the TCS provides bearing, bearing rate, attitude, and attitude rates for target vehicles utilizing special retro-reflectors.
In Discovery's middeck area, STS-64 will carry the Simplified Aid for EVA Rescue (SAFER) system, the Solid Surface Combustion Experiment (SSCE), the Biological Research in Canister III (BRIC-III) experiment, the Radiation Monitoring Equipment III (RME-III) experiment. Other experiments onboard STS-64 include Military Application of Ship Trails (MAST), Shuttle Amateur Radio Experiment-II (SAREX-II) and Air Force Maui Optical Site Calibration Test (AMOS).
