Preliminary Advanced Colloids
Experiments (PACE)
Objective:
♦ 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.
Relevance/Impact:
♦ 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.
Development Approach:
♦ 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).
