Ground testing for the first confocal Light Microscopy Microscope (LMM) Experiment. Procter and Gamble is working with NASA Glenn scientists to prepare for a study that examines product stabilizers in a microgravity environment. The particles in the tube glow orange because they have been fluorescently tagged with a dye that reacts to green laser lights to allow construction of a 3D image point by point. The experiment, which will be sent to the ISS later this year, will help P&G develop improved product stabilizers to extend shelf life and develop more environmentally friendly packaging.

iss026e032517 (3/8/2011) --- European Space Agency (ESA) Paolo Nespoli works with the Light Microscopy Module (LMM) in the U.S. Laboratory. 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.

ISS038-E-055240 (24 Feb. 2014) --- In the International Space Station's Destiny laboratory, NASA astronaut Mike Hopkins, Expedition 38 flight engineer, sets up the Advanced Colloids Experiment (ACE) housed in the Light Microscopy Module (LMM) inside the Fluids Integrated Rack. ACE studies microscopic particles suspended in a liquid.

iss062e014339 (Feb. 16, 2020) --- NASA astronaut and Expedition 62 Flight Engineer Jessica Meir configures the Light Microscopy Module inside the Fluids Integrated Rack. The specialized microscope is being readied to examine the transition of an ordered crystal to a disordered glass to determine how increasing disorder affects structural and dynamic properties. The Advanced Colloids Experiment-Temperature-4 (ACE-T-4) investigation controls disorder by controlling temperature in a series of samples and observes the microscopic transition in three dimensions.

iss059e101468 (6/12/2019) — Photo documentation aboard the International Space Station (ISS) of the ACE modules taken in the the Light Microscopy Module (LMM) during the ACE-T10 Module Configuration. The Advanced Colloids Experiment-Temperature-10 (ACE-T-10) investigates the growth kinetics, microscopic dynamics, and restructuring processes in ordered and disordered structures such as colloidal crystals, glasses and gels. The investigation studies crystal nucleation in colloidal fluids, the origin of ageing in glasses and gels, as well as the heterogeneous nature of the microscopic dynamics in these structures. The study must be conducted in microgravity, as gravitational stresses affect the structure and growth of these solids from colloids.

ISS036-E-019830 (24 June 2013) --- In the International Space Station’s Destiny laboratory, NASA astronaut Karen Nyberg, Expedition 36 flight engineer, speaks into a microphone while conducting a session with the Advanced Colloids Experiment (ACE)-1 sample preparation at the Light Microscopy Module (LMM) in the Fluids Integrated Rack / Fluids Combustion Facility (FIR/FCF). ACE-1 is a series of microscopic imaging investigations that uses the microgravity environment to examine flow characteristics and the evolution and ordering effects within a group of colloidal materials.

ISS034-E-056144 (21 Feb. 2013) --- Inside the U.S. Laboratory (Destiny) aboard the Earth-orbiting International Space Statio, NASA astronaut Kevin Ford, Expedition 34 commander, is seen with the Fluids Integration Rack (FIR)/Light Microscopy Module (LMM)/Advanced Colloids Experiment (ACE). ACE samples, which produce microscopic images of materials containing small colloidal particles, are scheduled for arrival on SpaceX-2 in the first week of March.
