I. Experiments in the Spacelab project - Spacelab and material processing facilities and experiments

The paper is introduced by a summary of the services available to the Spacelab user. Typical Shuttle-Spacelab flight profiles and Spacelab configurations are mentioned. The load carrying capacity and the capability and characteristics of the main subsystems, like electrical power and energy, environmental control as well as data management, are briefly described. The special constraints for the experiments to be flown on the first Spacelab payload will be discussed and the general purpose facilities (like furnaces and process chambers) to be used for carrying out the materials science experiments are described briefly. The cost aspects for performing experiments on Spacelab missions after the first mission are discussed.
