Light Microscopy Module (LMM)

The Light Microscopy Module (LMM) is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS). The LMM enables novel research of microscopic phenomena in microgravity, with the capability of remotely acquiring and downloading digital images and videos across many levels of magnification. The way that matter is organized and moves on the microscopic level profoundly affects the macroscopic world and an understanding of such processes helps scientists and engineers build more efficient materials and machines both for both the earth and space environments.

Advanced Colloids Experiments (ACE)

Advanced Colloids Experiments (ACE) To remove gravitational jamming and sedimentation so that it is possible to observe how order arises out of disorder and to learn to control this process. Small colloidal particles can be used to model atomic systems and to engineer new systems. Colloids are big enough (in comparison to atoms) to be … Read the rest ⇢


Constrained Vapor Bubble (CVB) The thermophysical principles underlying change-of-phase heat transfer systems are not well understood in microgravity conditions and are less than optimized even in earth gravity. This experiment proposes basic experimental and theoretical studies of the nonisothermal Constrained Vapor Bubble (CVB) under microgravity conditions. The CVB represents a passive, wickless heat pipe ideally … Read the rest ⇢

The LMM is being used in the Advanced Colloids Experiment Investigations


Preliminary Advanced Colloids Experiment (PACE) The data collected from Preliminary Advanced Colloids Experiment (PACE) ensures and optimizes the success of the Advanced Colloids Experiment (ACE). PACE determines which Light Microscopy Module (LMM) magnifications are usable before external vibrations blur the images. Both air and oil immersion microscope objectives (at 50x, 63x, and 100x magnifications) are … Read the rest ⇢
