Advances in space systems are providing challenging opportunities for the design of smaller, lighter, more efficient and cheaper satellite systems. A review of spacecraft power systems, structural materials, thermal design and cooling systems, electronic modules and advances in detector technology is provided. The science requirements for NOAA's advanced imager are presented. The NASA Jet Propulsion Laboratory design trade study for NOAA's 8-channel advanced imager shows that a 30 cm aperture mirror design can meet most of NOAA's requirements; though superior, the 45 cm mirror design option was abandoned due to instrument mass restrictions. The Aerospace Corporation was requested by NOAA to compare consolidated and distributed architectures. There appears to be no significant advantage for NOAA in pursuing distributed architecture for our future systems. A lighter overall mass is the key driver in reducing geostationary launch vehicle costs. Instrument design trade studies and spacecraft architectural studies are helping NOAA to plan for the future GOES systems.
