Summary and Next Steps

Global observations of Earth are essential to understanding how the planet is changing and the implications of these changes for society. In the coming decades, society’s prosperity and security will depend increasingly on Earth information, predictions, and warnings, which, in turn, rely fundamentally on sustained observations of the Earth system, linked to land and ocean observations and decision-support structures. Indeed, the need to improve this linkage was a key motivation for creating the Global Earth Observing System of Systems (GEOSS), which was initiated under U.S. leadership. During the next year the National Research Council’s Committee on Earth Science and Applications from Space will carry out its decadal study to recommend new observing systems for Earth science research and operations. The structure of its panels roughly reflects the socioeconomic benefit areas targeted by GEOSS (Table 4.1), an arrangement that will help ensure that the committee’s recommended Earth research and observations can be applied for the specific benefit of society—now and for future generations.

The Earth is a dynamic planet whose changes and variations affect our communications, energy, health, food, housing, and transportation infrastructure. Understanding these changes requires a range of observations acquired from a variety of land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and the USGS develop these tools, the NRC was asked by these agencies to carry out a decadal strategy survey of Earth science and applications from space. In particular, the study is to develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015, and a prioritized list of space programs, missions, and supporting activities to address these questions. This interim report outlines a key element of the study—the rationale for tying Earth observations to societal need—and identifies urgent near-term actions needed to achieve this goal. A final report, due in late 2006, will provide the list of recommended space missions, programs, and supporting.
