ARCHIVING ART AND BOOKS
The Lunar Codex uses digital and analog technology to preserve art, books, music, and more. The choice of media is highly dependent on the project mission.
The primary analog technology used by The Lunar Codex for Intuitive Machines Mission 1 (IM1) is NanoFiche™ technology. It can store orders of magnitude more content in the same space as microfiche, is impervious to temperature and humidity, and has a near-zero degradation factor.
At 600 dpi, NanoFiche can store 150,000 pages of text or photos can fit on a single 8.5”x11” sheet. It is currently the highest density storage media in the world.
For IM1, Codex graphics and text images are etched alongside other client images and enclosed in a time capsule on the Nova-C lander.
Analog technology was also used in our payload for Astrobotic's Peregrine Mission One (PM1) on Moonstone, in this case an etched silver disk that, for Codex purposes, confirms Dr. Peralta as payload provider for the program.
The primary storage technology used by Codex for PM1 is digital. This utilizes machine-readable and writeable graphics and text files in standard formats, stored on non-volatile memory cards.
NASA itself is using the same class of memory cards for archival purposes in its Space Launch System (SLS) rocket and Orion spacecraft Moon Pod during its Artemis I mission to orbit the Moon in November 2021.
The advantage of using digital technology is its ability to record enormous amounts of data with a very small weight profile. Degradation and errors are addressed through file redundancy; in our case, the main Lunar Codex files are have a redundancy factor of 2 or 3.
For PM1, the Codex files are enclosed in MoonBox cannisters provided by Astrobotic in partnership with DHL logistics. Codex uses file space reserved for Dr. Peralta in three physically separate MoonBoxes. The above are consolidated in a single time capsule deposited by the Peregrine Lander on the lunar surface.
For Griffin Mission 1 (GM1) - which will carry the Codex's third time capsule - a hybrid analog-digital storage system, consisting of alternating layers of nickel shielding/analog storage and digital memory cards.
