1. A heat resistive wall assembly for a space vehicle, comprising:

  • a. an inner wall formed from a heat resistive metal for providing both structural support for the vehicle and a heat sink for absorbing and dissipating heat applied to the outer surface of the vehicle;

    b. an outer wall formed from a heat resistive metal mounted over said inner wall in spaced relation thereto for radiating away heat applied to the outer surface of the vehicle, andc. at least a first resilient, evacuated insulator means disposed between said inner and outer walls to retard the radiant transmission of heat through said wall structure,wherein the space between the inner and said outer wall is vented so that said outer wall bears no atmospheric pressure load, and wherein the resiliency of said insulator means causes it to define a lengthened heat path between said inner and outer wall when ambient atmospheric pressure is relieved.
