Future science, operational, and commercial objectives in space can only be accomplished within cost and schedule constraints by rapidly developing and infusing new technology into missions, improving the capability to reliably predict performance in the space environment, and reducing operational costs. A trade study was performed to determine the optimum combination of space and ground developments and validations needed to accomplish these goals. A concept for a program, the Orbiting Technology Testbed Initiative (OTTI), was defined to address these goals. Results of the trade study and the resultant OTTI concept are described below.
