Project
The foundation plans "multiple...Arch libraries intended to preserve and disseminate humanity's knowledge across time and space for the benefit of future generations". The foundation is technology agnostic and will use whichever storage technology is best for its purposes including multiple technologies. The first method used is " 5D laser optical data storage in quartz", which will reportedly remain readable for up to 14 billion years, resist cosmic radiation, and can withstand temperatures up to 1,000°C. The foundation also plans on spinning off companies based on patents from research groups involved with the technologies it uses to fund itself in the future.Data Archives
Arch disks 1 through 5
As a proof of concept of theSolar Library
In December 2017, when Arch co-founder Nova Spivack heard that SpaceX was launching a Tesla into space, Spivack tweeted to Musk who jumped at the opportunity to include one on the mission - Musk was a book fan. Musk was also given the 1.1 disk for his private library. The 1.2 disk, named the 'Solar Library' by the Arch Mission Foundation also represents the first permanent space library, and is projected to orbit around the Sun for at least a few million years. The Solar Library was launched on the SpaceX Falcon Heavy test flight on February 6, 2018, inside Musk's red Tesla Roadster. The payload was placed in an elliptical orbit that extends nearly 243 million miles from the Sun at its farthest point.Lunar Library
In 2019, the Arch Mission sent the Lunar Library, a 30 million page library of books, data, images and a copy of English Wikipedia to the Moon aboard the IsraeliMethod of storing information
The methods used to store the library was by etching high-resolution microscopic images into 25 thin layers of nickel. The first four layers include approximately 60,000 pages of textbooks, books on language, and information to be able to unravel the deeper layers. DNA digital data storage is also used to store 20,000 images and 20 notable books. The analog layers of the Lunar Library have instructions to decode the DNA and be able to retrieve the digital information in it.Other projects
Arch hopes to seed the Solar System with millions and possibly billions of archives into "all kinds of locations". It wants to build a permanent library on the Moon and on Mars. Arch envisions its small light-weight disks might be an alternative means of moving large amounts of data between Earth and Mars as opposed to radio signals. Longer term they envision connecting the Arch Libraries through a decentralised read-write data sharing network that spans the Solar System. Data in the libraries will include Wikipedia, Project Gutenberg, human genomes, and other large open-data sets. They will also allow donations of money to instruct that certain data be included, and will do so without censorship of what can be included. The foundation cites the likelihood that a being developed enough to find and read the information would already possess significant technology as the reason for not prioritizing scientific data sets. In February 2018, the Arch Mission successfully placed an archive called the Orbital Library, which contains a copy of Wikipedia, into low-Earth orbit. The Arch Mission has also built a payload called the Lunar Library, which serves as a backup to planet Earth and contains scientific, cultural and historical information in almost 30 languages and several encyclopedias including Wikipedia. The Lunar Library was set to arrive on the Moon on the Israeli spacecraft '' Beresheet'', but it crashed landed on the Moon in May 2019. Despite this, the 30-million page Lunar Library possibly survived due to the strength of its construction. In 2021, Arch Mission announced partnerships withSee also
