NASA Earth System Observatory

NASA is developing the Earth System Observatory, the core of which is five satellite missions providing critical data on climate change, severe weather and other natural hazards, wildfires, and global food production.

These observations will address the most pressing questions about our changing planet, as identified in the 2017 Earth Science Decadal Survey by the National Academies of Science, Engineering, and Medicine. The core of the Observatory will focus on five areas: Aerosols; Cloud, Convection, and Precipitation; Mass Change; Surface Biology and Geology; and Surface Deformation and Change. Consistent with the Academies’ recommendations, NASA will augment the core with competitively selected Earth Explorer missions, to infuse innovation and deliver additional high-priority observations.

Each of the missions will deliver important environmental measurements. Taken together, as a single Observatory, NASA will have a holistic, 3D view of Earth to better understand how our planet’s complex systems work together and improve our capability to predict how our climate may change. NASA’s Open Source Science strategy is the key to bringing the data from these missions together into a single observatory to help understand the earth as a system and accelerate our ability to use this understanding. These observations will better inform decision-makers on how our planet is changing, with greater precision on previously unimaginable scales – from entire continents down to individual trees, from atmosphere to bedrock.

NASA Earth Science Division Response to COVID-19

During the pandemic, NASA Earth Science Division (ESD) has continued to collect Earth-observing data, capturing the changes in our planet’s systems, particularly in response to changes in human behavior during societal distancing and related shutdowns.

Read more about ESD’s scientific data and research related to the pandemic, and see the changes on NASA’s COVID-19 dashboard, and on a global dashboard produced by NASA, ESA and JAXA.

About NASA Earth Science

NASA’s Earth Science Division (ESD) missions help us to understand our planet’s interconnected systems, from a global scale down to minute processes.

ESD delivers the technology, expertise, global observations, and applications that help us map the myriad connections between our planet’s vital processes and the climate effects of ongoing natural and human-caused changes.

Using observations from satellites, instruments on the International Space Station, airplanes, balloons, ships and on land, ESD researchers collect data about the science of our planet’s atmospheric motion and composition; land cover, land use and vegetation; ocean currents, temperatures and upper-ocean life; and ice on land and sea. These data sets, which cover even the most remote areas of Earth, are freely and openly available to anyone.

ESD offers end-to-end development, launch, data collection, analysis, and application of its missions, including those with partners in U.S. and international government, and the private sector. ESD also sponsors research and extends science and technology education to learners of all ages, inspiring the next generation of explorers.
