In fact, after all their Golden Record, perhaps one reflecting the power is gone, carrying these artifacts becomes changes in technology since 1977— some kind the primary mission of the spacecraft. of a quantum-nano-superconducting Golden The voyager golden record The two Pioneers bore the now iconic Record! 24 Planetarian Vol 46 No 3 - September 2017 But the mission included no message at all, except for some coins (U.S. state quarters) and other tokens. It also, in a noble gesture, carries some of the ashes of Pluto’s discoverer Clyde Tombaugh. But there is no coherent message designed to be understood by ET. An opportunity lost? It seemed a lost opportunity, until I had the Jill Tarter Bob McDonald Gail Glasper Albert Yu-Min Lin idea of making a message on Earth and upload- ing it to the spacecraft. In 2012 I was designing a logo for the company Made in Space, which was field-testing 3D printers on the Interna- tional Space Station. Break a wrench in orbit and print out your own replacement wrench from a file sent up from Earth. If we could build a wrench in space, why not a message? Daniela DePaulis Carolyn Barnett Derrick Pitts Kaoru Kimura Made in Space gave the International Space Station a unit to test in orbit, bearing my logo on its side.
