writes "Voyager 1 is expected to reach interstellar space soon. It will be the first made made object to cross the heliosphere, which is the final stop in our solar system. Voyager 1, famously contained a gold phonographic record. The record was filled with iconic sights, images, and sounds from earth, and the prevailing message, "we come in peace". The disc was comprised by a man named Carl Sagan, and it contained many pieces of art, songs, and images, that are all copy-written. According to NASA, "Most of the material they used was copyrighted by the creators/owners and Sagan had to get copyright releases in order to assemble the original record. Subsequently, Warner Multimedia was able to obtain copyright releases for the 1992 version of "Murmurs of Earth" .. Unfortunately, the book and CDROM are no longer being published and are hard to find as a set.". Some used copies still exist for sale, versions of Murmurs of Earth published before 1992 will not contain the CDROM. Perhaps the next interstallar probe should be run on open source software and use creative commons music, so our first encounter doesn't involve us suing aliens for copyright infringement."
