2. 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.

3. 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.

4. 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

5. 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.
