Set out almost 30 years ago, the voyager probes are coming close to exiting the Heliosphere. The probes have collected some immensely important discoveries of our solar system, such as the ocean under the frozen surface of Europa and the frenzied magnetic poles on Uranus. By 2020, it is predicted that the plutonium powering the probes will become inert and the Voyager 1 and 2 will become soaring containers that carry the 'Golden Record'. As pictured above, the discs contain music, photos, and greetings in 55 languages along with a message from the Secretary General of the United Nations.
