  Earth as Art  In 1960, the United States put its first Earth-
observing environmental satellite into orbit around the planet.
Over the decades, these satellites have provided invaluable
information, and the vantage point of space has provided new
perspectives on Earth. The NASA e-book, Earth as Art, is free
and celebrates Earth’s aesthetic beauty in the patterns, shapes,
colors, and textures of the land, oceans, ice, and atmosphere.
The book features 75 stunning images of Earth from the Terra,
Landsat 5, Landsat 7, EO-1, and Aqua satellites. Sensors on
these satellites can measure light outside of the visible range,
so the images show more than what is visible to the naked eye.
The images are intended for viewing enjoyment rather than
scientific interpretation. The beauty of Earth is clear, and the
artistry ranges from the surreal to the sublime. The book can be
