The special data device SpaceX's Falcon Heavy sent to orbit is just the start

On board the Tesla Roadster that Elon Musk sent hurtling towards the sun, aiming for a long, leisurely Earth-Mars orbit, there were a few pieces of miscellaneous cargo.

A so-called 'Starman,' which is a life-size mannequin wearing a production version of the SpaceX crew spacesuit; a miniature car created by Hot Wheels to commemorate the Roadster and its primary passenger; and something called an Arch (pronounced "Ark"), which is not so easy to summarily describe.

The Arch on board is a data crystal (sort of like a Jedi Holocron if you're mad for Star Wars lore) that contains all three books from Isaac Asimov's classic Foundation trilogy. It's actually a modest amount of data relative to the possibilities of the storage medium – in this case, a quartz silica structure which, using 5D optical storage techniques, can eventually achieve a max storage capacity of 360 terabytes on a disk just 3.75 inches in diameter.

But why shoot a tiny quartz disc into space? Why Foundation, and why aboard the Falcon Heavy, the crowning achievement of Elon Musk's SpaceX private launch venture thus far?

First, while the disc itself and the technology behind it (developed by University of Southampton's Dr. Peter Kazansky and his research team) is incredibly interesting (it's expected to last for over 14 billion years, even accounting for outer space dangers including cosmic radiation) – it's not the definition of what an Arch actually is. That, according to Arch Mission co-founder Nova Spivack, is actually something much more ambitious, broad in scope and technology agnostic.

The Arch Mission was actually inspired by Asimov's Foundation series ..... more .....
