The german microgravity program: Objectives and present status

Within the space program of the Federal Republic of Germany the microgravity program in connection with the utilization of SPACELAB constitutes a central task which determines the long-term program concepts and also their relation to German participation in future ESA programs.The scientific preparatory programs under way for some years now have made further progress. Extensive flight experience and valuable scientific results were obtained on the basis of successful rocket pre-programs. The present paper describes the process in which scientific and organisational priorities are being defined for the planning and execution of the experimental programs.In order to obtain a sufficient number of flight opportunities, payloads for SPACE SHUTTLE missions, in particular under the NASA GAS Program, as well as experimental equipment such as the materials laboratory (MSDR) for FSLP are being developed. The German program focuses on preparing a German SPACELAB mission D1 planned for 1985, which is intended to verify the applicability and efficiency of manned research laboratories for industry and the scientific community. A second emphasis is on preparing the use of SHUTTLE-supported re-usable space platforms.
