AUDIE CORNISH, HOST:
Now, a prize that's making a return: the Longitude Prize.
ROBERT SIEGEL, HOST:
It was set up in 1714 by the British government to solve the greatest challenge of that time: Pinpoint a ship's location at sea by knowing its longitude.
CORNISH: Three hundred years later, there's a video announcing its return.
UNIDENTIFIED MAN #1: We're at the dawn of a new world.
SIEGEL: Its committee is led by Lord Martin Rees, a professor at Cambridge University.
