The voices of 50 New Zealanders will be sent more than 750,000 kilometres through space and time in a competition to celebrate Doctor Who's 50th anniversary.
The voices will be sent using a method called a moon bounce - a rare method developed by the US military in 1940 which involves bouncing an audio message off the moon's surface to an Earth-based receiver in a matter of seconds.
The method is currently practised by only a niche group of radio astronomy specialists.
One of the specialists has partnered with television channel Prime to launch the competition.
Depending on the stage of the lunar cycle and the position of the moon, voice messages return back to Earth with varying levels of galactic distortion.
