Summary:—

Progress in understanding the atmosphere heating problems of space vehicles at hyperbolic entry speeds is reviewed. The various sources of aerodynamic heating are discussed along with the response of suitable heat shield materials to these inputs. It is shown that even for optimum shaped vehicles the problems are formidable at entry speeds greatly in excess of Earth parabolic speed. Much additional research, particularly of ablation materials, will be needed to effect satisfactory designs for such craft.
