The Earth Observing System (EOS) is a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. EOS is a major component of the Earth Science Division of NASA's Science Mission Directorate. EOS enables an improved understanding of the Earth as an integrated system. The EOS Project Science Office (EOSPSO) is committed to bringing program information and resources to program scientists and the general public alike.

Breaking News
Human Influences Challenge Penguin Populations (July 1) Pronounced warming in the Antarctic, as well as commercial fishing, mining, and oil and gas development at lower latitudes, has led to declines in many species, including the Galápagos, Peruvian, and African species of penguin, according to scientists.

Open Issues
* Our knowledge of the interior of the Earth is derived almost entirely from highly indirect evidence. How can we get more information?
* Despite substantial increases in the solar "constant" the average temperature on the surface of the Earth has remained very stable for several billion years. The best theory is that this has been accomplished by varying the amount of carbon dioxide in the atmosphere to regulate the greenhouse effect. But just how is this done? The Gaia Hypothesis asserts that the biosphere actively regulates it. More detailed information about Venus and Mars may provide clues.
* How much more carbon dioxide can we dump into the Earth's atmosphere before it ends up like Venus?
