Nasa erth update

Ancient Greek, Hindu, and Buddhist philosophers saw fire, air, water, and earth as the prime elements—the fundamental building blocks of the natural world. Modern science recognizes 118 elements (so far) and now uses experimental methods for understanding the physical world. Yet fire, air, water, and earth still help us see the beauty, raw power, and dynamics of our planet.

From its origins, NASA has studied the atmosphere, the solid but moveable earth, fire and heat, and water in its various forms. We have done this in novel ways, using innovative tools to study Earth from the edge of the atmosphere to the ocean surface to formations within the crust. Using satellites and crewed spacecraft, we look at Earth in macrocosm and microcosm, from the flow of one mountain stream to the flow of jet streams.

Since 1999, Earth Observatory has published thousands of images of this awesome and ever-changing planet. Now we want you to view elemental fire, air, water, and earth as scientists and astronauts see them from space—and then pick your favorite images in a five-round tournament. Each week from March 1 to April 5, you can help narrow the field from 32 nominees down to one champion.

Visit the Tournament Earth page to vote for images, open a larger version, see complementary images, and learn more about them.

No Longer Just for Astronauts
When the DSCOVR mission was conceived in the late 1990s, one of the central ideas was to provide daily, natural-color views of the entire Earth so that everyday citizens could see it. Seventeen years later, we have that view.
