Abstract	Abstract The mission of NASA's Earth Science Enterprise (ESE) is to develop a scientific understanding of the Earth system and its response to natural and human-induced changes to enable improved prediction of climate, weather, and natural hazards for present and future generations. The ESE has an end-to-end strategy to assure that information, understanding, and capabilities derived from its research program achieve maximum usefulness to the scientific and decision-making communities. Small satellites ( 500 kg) have been crucial contributors to satisfying the research strategy since the inception of NASA's Earth observation program in the 1960s. In the last decade, NASA's ESE has placed a renewed emphasis on small satellites. This reemphasis reflects advancements in compact sensor, small satellite bus, and launch vehicle technologies in addition to management innovations. Near term and advanced planning suggest that this trend will continue. A number of related small satellite missions have been recently launched, are in development, or are planned. Multi-satellite constellations under study include small satellites as key architectural elements. Studies indicate that low cost, capable microspacecraft along with compact sensors and increased autonomy are technology enablers to the sensorwebs and associated distributed spacecraft infrastructure required to realize the long-term NASA Earth Science Vision (ESV).
