NASA has a great collection of ebooks about space, science, aeronautics, and the history of science. All DRM-free PDFs. Your tax dollars, at (good) work! (Thanks, Alan!) READ THE REST
Wow, the Earth As Art ebook is simply amazing.

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. This book 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.
Apparently there's an iPad app as well:
Nope, Vanguard 2 had a cloud scanner in Feb 1959- designed and possibly built before NASA even existed. Of course, Vanguard was Navy, so I could easily see a turf debate happening.
