Most discipline groups found a need for Shuttle missions entirely dedicated to their own science but also recognized the potential savings associated with missions with multiple objectives. The study group identified some problems of instrument design and integration and, to some extent, the kinds of operational procedures that will be needed for multipurpose missions.

Most disciplines identified major programs requiring observing times considerably in excess of the 28-day maximum duration envisaged

The weight penalties of carrying a Spacelab raise the question of whether real-time control and evaluation would be better supplied from a ground-based scientific group or from scientists carried in flight. If a communications system from the Shuttle to the ground, giving continuous global coverage with a high rate of data interchange, were available, then ground control might be preferable to carrying a manned Spacelab.

It is crucial to set design and test criteria for flight hardware and to use a management system similar to those used for rocket-launched payloads, which are low in cost compared with satellite payloads. The reduction of overall costs in payloads that are separated from the Shuttle is a more complex question that requires detailed cost-effectiveness studies; the reduction of weight and size limitations may permit significant savings.
