ABSTRACT:
A high energy, e.g., ultraviolet (UV), catalyzed decomposing foam encapsulating a payload to be boosted in space provides an ultra-light weight, adaptable means to facilitate survival of much lighter, smaller satellites and space hardware under boost environment. The decomposable foam is to contain multiple satellites within a booster payload in lieu of the traditionally heavy and complex structural framework. The catalyzed decomposing foam significantly lowers the weight and structure of all space hardware. This packaging system is especially beneficial where several or even hundreds of satellites are required for a constellation system, thereby significantly benefiting all technologies applied in space, ranging from the telecommunication industry to DOD applications. In addition to weight and cost savings, advantages of this foam are many in that it is adaptable to any payload shape as it may be injected, sprayed, formed, molded, easily cut or manufactured to support any geometry required.
