NASA Earth Science
NASA Earth Science, formerly called NASA Earth Science Enterprise (ESE) and Mission To Planet Earth (MTPE), is a NASA research program "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". NASA supports research in the Earth sciences and, as part of its Earth Observing System (EOS), launches and maintains Earth observing satellites to monitor the state of the climate, atmospheric chemistry, ocean and land ecosystems.
