Earth Science Missions of the National Aeronautics and Space Administration
The purpose of the National Aeronautics and Space Administration (NASA) Earth science program is to develop a scientific understanding of the Earth's system and its response to natural or human-induced changes, and to improve the prediction of climate, weather and natural hazards. A major component of NASA’s Earth Science Division is a coordinated series of satellite and airborne missions for long-term global observations of the land surface, biosphere, solid Earth, atmosphere and oceans. This coordinated approach enables an improved understanding of the Earth as an integrated system, enhancing the ability of the international scientific community to advance global integrated Earth system science using space-based observations. The agency's research encompasses solar activity, sea level rise, the temperature of the atmosphere and the oceans, the state of the ozone layer, air pollution, and changes in sea ice and land ice.
