If you could send one message about humanity into deep space, what would it be?

Almost 50 years after the Voyager mission sent the sounds of earth into the galaxy, a new project is capturing a contemporary soundtrack for another space launch.

More than 1700 people have recorded messages for the HUMANS Deep Space Message project, via a collaboration with Sydney's Powerhouse Museum.
