and very limited resources. As the breadth of the country’s space mission has expanded, the necessary technological developments have become less clear, and more effort is required to evaluate the best path for a forward-looking technology development program. NASA has now entered a transitional stage, moving from the past era in which desirable technological goals were evident to all to one in which careful choices among many conflicting alternatives must be made. This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by NASA’s Office of the Chief Technologist can be enhanced in the face of scarce resources by focusing on the highest-priority technologies.
