Abstract: A micrometeoroid and orbital debris-integrated multi-layer insulation (MMOD/IMLI) structure including at least one ballistic layer, which may be flexible, and at least one insulation layer, which may also be flexible is described. The ballistic layer or layers and the insulation layer or layers may be separated by a plurality of spacers. In one example, the spacers include a leg extending obliquely between the ballistic layer and the insulation layer. The spacer may include three deformable legs defining a tri-pod configuration with the tri-pod configuration including a ring supporting the legs.
