Asimov in Space
In addition to Adams' "A Hitchkiker's Guide to the Galaxy," Starman's Tesla also carried Isaac Asimov's iconic "The Foundation Trilogy" book series. It was part of a data package on an Arch (pronounced "Ark"), a laser optical quartz storage device designed to survive the harsh environment of space. The book series was the original inspiration for the Arch mission.
