A Multi-Layer Insulation includes a fixed membrane, a flexible membrane, and at least one electrical insulating layer. The fixed membrane adjoins a substrate. The fixed membrane includes a fixed electrical conducting layer. The flexible membrane includes a thermal insulator and a flexible electrical conducting layer. The flexible membrane is configured to furl into a rolled condition absent application of a voltage across the fixed electrical conducting layer and the flexible electrical conducting layer and is configured to unfurl over the fixed membrane responsive to application of a voltage across the fixed electrical conducting layer and the flexible electrical conducting layer. The at least one electrical insulating layer is located between the fixed electrical conducting layer and the flexible conducting layer. The at least one electrical insulating layer is chosen from a fixed electrical insulating layer of the fixed membrane and an inner electrical insulating layer of the flexible membrane.
