Space platforms - A cost effective evolution of Spacelab operation

Abstract The Shuttle/Spacelab mode of space operations will soon provide ready access to space for a wide varity of experimenters. When the full capabilities of this system are utilized, an important tool will have been added to the research and development phases of the various disciplines. Although significant benefits can now be envisioned from using these systems, it has become evident that additional benefits to the users could be achieved if some of the available resources were augmented. Those resources include: power, thermal control; duration on orbit; stability; and orientation. This paper reports planning efforts in progress to determine what augmentation these systems should provide. To properly bound the study effort, a projection of the potential Spacelab activity through the 1980 decade is developed. Three major augmentation systems are examined and the benefits provided by each are outlined. One of these systems, the Science and Applications Space Platform, represents a very attractive concept and the potential cost effectiveness is examined in detail. After these analyses are completed, general conclusions on the cost and other benefits of Space Platforms are provided.
