Control-Structure Integration (CSI) technology will be needed for the success of many future space missions, however, this technology will not be seriously considered for use by program managers if it is not first demonstrated in space. This paper will present the results of a study that developed a concept of a relatively low-cost CSI laboratory available to government, industry, and academic guest investigators by using the QuickStar bus, a flight-proven smallsat, launched as a secondary payload aboard a Delta II launch vehicle. A representative CSI experiment payload was developed, which included a structural test article, sensors, actuators, and disturbances sources, to be integrated into the bus. The resulting concept for a CSI orbital lab was evaluated based on how well the concept satisfied generally accepted CSI flight-test objectives, and its cost and reliability.
