56-57) NASA has developed a draft set of technology roadmaps to guide the development of space technologies under the leadership of the NASA Office of the Chief Technologist.1 The NRC appointed the Steering Committee for NASA Technology Roadmaps and six panels to evaluate the draft roadmaps, recommend improvements, and prioritize the technologies within each and among all of the technology areas as NASA finalizes the roadmaps.

These criteria were chosen to capture the potential benefits, breadth, and risk of the various technologies and were used as a guide by both the panels and the steering committee to determine the final prioritization of the technologies. Broad community input was solicited from a public website where more than 240 public comments were received on the draft roadmaps using the established steering committee evaluation criteria and other descriptive factors.

Furthermore, the steering committee constrained the number of highest-priority technologies to be included in the final list in the belief that in the face of probable scarce resources, focusing initially on a small number of the highest-priority technologies offers the best chance to make the greatest impact, especially given that agency mission areas, particularly in exploration, are being refined and can be shaped by technology options. Within this organizing framework, technology objectives were defined by the steering committee to address the breadth of NASA missions and group related technologies.

TOP TECHNICAL CHALLENGES With the three technology objectives defined, the steering committee evaluated the top technical challenges from the panels' prioritized list of challenges for each roadmap TA01 through TA14. The top 10 technical chal lenges for each of the three technology objectives are described in Table S.2.

(3.1.3) CROSSCUTTING FINDINGS AND RECOMMENDATIONS In reviewing and evaluating the draft roadmaps and considering the purpose and strategic goals for the advanced technology development program managed by OCT, the steering committee formed some general observations concerning the program as a whole and reached some conclusions on how the effectiveness of the program can be maintained or enhanced.

The steering committee then evaluated those 83 technologies. Through an organizing framework relating objectives, challenges, and individual technologies, the prioritization process across all roadmaps identified 7 or 8 technologies for each of three independent technology objectives, for a total of 16 unique technologies that this report recommends be emphasized over the next 5 years of the 5- to 30-year window of the technology roadmaps.

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 alterna tives 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.
