Abstract: A container apparatus for exposing an article to an external environment, the apparatus including a sidewall with an interior having an inner surface, the sidewall terminating in a first margin and an opposing second margin. The container apparatus also includes a capsule having an outer periphery and an inner void holding the article, the outer periphery is slidably engaged to the sidewall inner surface, the capsule having a split boundary separating the capsule into a plurality of partial capsule elements. The capsule having a closed state with the partial capsule elements being adjacent at the boundary while slidably engaged to the sidewall with the void separated from the environment and the capsule being able to have an open state without the slidable engagement as the partial capsule elements are separated at the boundary with the void open to the environment, thus exposing the article to the environment.

Abstract: Composite flexible multilayer insulation systems (MLI) were evaluated for thermal performance and compared with currently used fibrous silica (baseline) insulation system. The systems described are multilayer insulations consisting of alternating layers of metal foil and scrim ceramic cloth or vacuum metallized polymeric films quilted together using ceramic thread. A silicon carbide thread for use in the quilting and the method of making it are also described. These systems are useful to provide lightweight thermal insulation for a variety of uses, particularly on the surface of aerospace vehicles subject to very high temperatures during flight.
