The next generation of Earth observing satellites and sensor networks will face challenges in supporting robust high rate communications links from the increasingly sophisticated onboard instruments. Emerging applications will need data rates forecast to be in the 100's to 1000's of Mbps. As mission designers seek smaller spacecraft, challenges exist in reducing the size and power requirements while increasing the capacity of the spacecraft's communications technologies. To meet these challenges, this work looks at three areas of selected space communications and data services technologies, specifically in the development of reflectarray antennas, demonstration of space Internet concepts, and measurement of atmospheric propagation effects on Ka-band signal transmitted from LEO.

The Committee for the Review of NASA's Pioneering Revolutionary Technology (PRT) Program and its three supporting panels were charged by the National Aeronautics and Space Administration (NASA) with assessing the overall scientific and technical quality of the PRT program and its component programs, along with their associated elements and individual research tasks. Major issues addressed in the review include (1) research portfolios, (2) research plans, (3) technical community connections, (4) methodologies, and (5) overall capabilities. As reflected in the organization of the report, a two-pronged assessment was developed. Each panel provided a detailed assessment of the program under its purview, which was refined and updated over the course of the review. The committee, composed mainly of representatives from each panel, integrated and evaluated the panel results and provided top-level advice on issues cutting across the entire PRT program.
