Abstract
A spacecraft multilayer insulation blanket is made from multiple sheets of polyimide e.g. KAPTON. A preferred six sheet embodiment employs three carbon loaded sheets (26, 32, 34) separated by two dielectric sheets (28, 30). A third dielectric sheet (36) insulates the carbon loaded sheets from the spacecraft body. The outermost carbon loaded sheet (32) has a high resistivity and is primarily transmissive while the other two carbon loaded sheets (26, 34) have a low resistivity and are primarily reflective.
