Abstract

The DLR Microgravity User Support Centre (MUSC) in Cologne has supported microgravity experiments in the field of materials and life sciences since 1979. In the beginning of user support activities, MUSC tasks comprised the basic ground and mission support, whereas present programmes are expanded on, for example, powerful telescience and advanced real time data acquisition capabilities for efficient experiment operation and monitoring. In view of the Space Station era, user support functions will increase further. Additional tasks and growing responsibilities must be covered, e.g. extended science support as well as experiment and facility operations. The user support for TEMPUS IML-2, under contract of the German Space Agency DARA, represents a further step towards the required new-generation of future ground programme. TEMPUS is a new highly sophisticated Spacelab multi-user facility for containerless processing of metallic samples. Electromagnetic levitation technique is applied and various experiment diagnosis tools are offered. Experiments from eight U.S. and German investigator groups have been selected for flight on the second International Microgravity Laboratory Mission IML-2 in 1994. Based on the experience gained in the research programme of the DLR Institute for Space Simulation since 1984, MUSC is performing a comprehensive experiment preparation programme in close collaboration with the investigator teams. Complex laboratory equipment has been built up for technology and experiment preparation development. New experiment techniques have been developed for experiment verification tests. The MUSC programme includes thorough analysis and testing of scientific requirements of every proposed experiment with respect to the facility hard- and software capabilities. In addition, studies on the experiment-specific operation requirements have been performed and suitable telescience scenarios were analysed. The present paper will give a survey of the TEMPUS user support tasks emphasizing the advanced science support activities, which are considered significant for future ground programmes.
