When applying voltage or power to each coating, the emissivity changes and the process rejects more heat into space, similar to photo-grey or photo chromic sunglass lenses becoming darker when facing direct light. With an acronym that sounds familiar in another space galaxy, the second AFRL trial, Variable Emissivity Radiator Aerogel Insulation Blanket Dual Zone Thermal Control Experiment Suite for responsive Space, or VADER, positioned directly below MHTEX, involves 10 separate coatings, manufactured by Eclipse Energy Systems, St. "The trial's goal will be to measure the on-orbit performance of the capillary pump loop in its efforts to significantly cool a structure by transferring heat to a radiator, which is not located near the heat source." "The MHTEX will be a great technology for the Air Force, as it will enable significant capabilities for the warfighter by providing the next generation of spacecraft with improved cooling," said Andy Williams, Thermal Systems lead, AFRL's Space Vehicles Directorate. With the dimensions of two feet long by three feet high by three feet long, MHTEX, a one-year trial, will attempt to validate the employment of a capillary pump loop to cool a spacecraft eight times more efficiently than current systems.
