Carl Sagan’s Voyager Golden Record — of sounds of Earth, recorded greetings and an eclectic mix of music that was sent into space — has long been out of print and pretty much unobtainable for decades.

One copy of the record is attached to NASA’s Voyager 1 spacecraft, which has entered interstellar space, the farthest artifact ever tossed out by humanity. A second copy, on Voyager 2, is not quite as distant, just 10 billion miles away.

Both are receding from Earth at more than 35,000 miles per hour.

Not even Dr. Sagan, the Cornell astrophysicist who led the creation of the record in 1977 for the listening pleasure of any aliens who happened upon it, could get a copy.

He asked. NASA said no.

But now, a Kickstarter crowdfunding project begun on Wednesday is planning to reissue it, long a dream of David Pescovitz, an editor and managing partner at Boing Boing, the technology news website, and a research director at the nonprofit Institute for the Future.
