Arch Mission Foundation: “The Lunar Library™ represents the first in a series of lunar archives from the Arch Mission Foundation, designed to preserve the records of our civilization for up to billions of years. It is installed in the SpaceIL “Beresheet” lunar lander, scheduled to land on the Moon in April of 2019. The Lunar Library contains a 30 million page archive of human history and civilization, covering all subjects, cultures, nations, languages, genres, and time periods. The Library is housed within a 100 gram nanotechnology device that resembles a 120mm DVD. However it is actually composed of 25 nickel discs, each only 40 microns thick, that were made for the Arch Mission Foundation by NanoArchival. The first four layers contain more than 60,000 analog images of pages of books, photographs, illustrations, and documents – etched as 150 to 200 dpi, at increasing levels of magnification, by optical nanolithography. The first analog layer is the Front Cover and is visible to the naked eye. It contains 1500 pages of text and images, as well as holographic diffractive logos and text, and can be easily read with a 100X magnification optical microscope, or even a lower power magnifying glass…”
