PACE-1 PROJECT DOCUMENTS
♦ PACE-1: Risk mitigation for future Advanced Colloids Experiments (ACE). Determine and document which magnifications are usable (50x, 63x, 100x) with both air and oil, immersion microscope objectives in an ISS vibration environment.
♦ PACE-2: View dilute solution of dyed particles. Different size particles combined in an actual (fluid filled and pre-sealed) sample cell. Dye each particle size a different color, which can be selected for viewing with the filter cube in the microscope, one size at a time.
♦ Develop crew procedures for changing PACE and ACE samples.
♦ Use this opportunity to characterize the capability of conducting high magnification imaging with LMM using a test target and test particles. This will be done to find what are the minimum size particles are needed for ACE, given microscope vibration and magnification results.
♦ Compare Space Acceleration Measurement System (SAMS) data with image quality to correlate operation windows.
♦ Run through various operational scenarios (regular crew activity (nominal / exercise / sleep), equipment operations (pumps, actuators, thruster firing, etc.)
♦ Compare results obtained with different microscope objective index matching fluids (air and oil).
