Light Microscopy Modle, LMM, Ground Unit Testing, GU. Control Systems Engineer using a small magnet to maneuver a 1mm metal stir-bar into a colloid sample fluid-filled capillary. The capillary tubes of sample fluid will be filled and sealed. The sample fluid supplied by a Principal Investigator typically contains some hazardous/toxic chemicals that she must ensure will not leak and put the astronauts at risk. On-orbit on the LMM, ‘insitu mixing’ is used, which uses electromagnetic inductors to stimulate the metal stir-bar to mix the fluid within the sealed capillary.

Astronaut Virgil "Gus" Grissom at the controls of the Visual Docking Simulator. From A.W. Vogeley, "Piloted Space-Flight Simulation at Langley Research Center," Paper presented at the American Society of Mechanical Engineers 1966 Winter Meeting, New York, NY, November 27-December 1, 1966. "This facility was [later known as the Visual-Optical Simulator.] It presents to the pilot an out-the-window view of his target in correct 6 degrees of freedom motion. The scene is obtained by a television camera pick-up viewing a small-scale gimbaled model of the target." "For docking studies, the docking target picture was projected onto the surface of a 20-foot-diameter sphere and the pilot could, effectively, maneuver into contract. this facility was used in a comparison study with the Rendezvous Docking Simulator - one of the few comparison experiments in which conditions were carefully controlled and a reasonable sample of pilots used. All pilots preferred the more realistic RDS visual scene. The pilots generally liked the RDS angular motion cues although some objected to the false gravity cues that these motions introduced. Training time was shorter on the RDS, but final performance on both simulators was essentially equal. " "For station-keeping studies, since close approach is not required, the target was presented to the pilot through a virtual-image system which projects his view to infinity, providing a more realistic effect. In addition to the target, the system also projects a star and horizon background. "

The anechoic chamber walls are covered with a material that absorbs electromagnetic energy allowing the anechoic chamber to simulate a space environment. The antenna test facility is utilized to test antenna radiation distribution pattern performance for spaceflight applications in electromagnetic environments.
