Microscopic radiator flying on 'skin' of a NASA spacecraft to launch March 14

A small team of researchers from the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., in conjunction with NASA Goddard Space Flight Center (GSFC), has developed a novel radiator so small its components are only visible under a microscope. The temperature control device, formally known as the "Variable Emittance (Vari-E) Coatings for Thermal Control," is based on MicroElectroMechanical Systems (MEMS) technology employing shutters so small that several abreast are smaller than the width of a single human hair.
