SHOT II Mission Objectives Controlled release of R-134a at 70+ kft. Take Infrared images of the plume resulting from the R-134a release. Analyze the results based on the outline and the physical characteristics of the plume. Further analyze how different factors such as temperature and pressure affect the behavior of the plume characteristics.

SHOT II / UN-6 Connection UN6 Mission: Space Situational Awareness. Detecting nearby spacecraft by detecting thruster plumes using IR imager. Analyze images for the presence of thruster plume. Based on the SHOT II data, decide what data pattern UN6 should detect using IR imager.

SHOT II Design and Test Details Use GPS as a primary position device and pressure as secondary position device. Using GPS data, release R-134a at about 70k ft. If GPS fails use pressure data. Capture and store IR images simultaneously with GPS, pressure and temperature data. Mass Compliance

Expected Results The plume from the R-134a is expected to be detectable by the IR camera above 80,000 feet. For UN-6, the plumes are expected to be visible from at least 10 meters. Based on vacuum tests, it is expected that the R-134a will be visible to the IR device under test conditions. The vacuum test chamber is 1.5 meters long. Actual visibility in space may be different.
