As the probe it is attached to is relatively small and hard to see, it is difficult to assess the likelihood of discovery of the probe in the long term— it depends upon where it ends up. If it is found, and not destroyed, it is certain that it will take a very long time in human terms, and thus the record is a symbolic statement rather than a serious attempt to enter a dialogue with aliens.
The Voyager spacecraft will be the third and fourth human artifacts to escape entirely from the solar system. Pioneers 10 and 11, which were launched in 1972 and 1973 and preceded Voyager in outstripping the gravitational attraction of the Sun, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future.
With this example before them, NASA placed a more comprehensive (and eclectic) message aboard Voyager 1 and 2 – a kind of time capsule, intended to communicate a story of our world to extraterrestrials.
This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. — U.S. President Jimmy CarterJames Earl Carter, Jr. born October 1, 1924) was the 39th ( 1977 1981) President of the United States. He had previously served one term as Governor of Georgia. Carter's administration marked the decline of U. power overseas and an economic recession..
The Voyager message is carried by the Voyager Golden Record; a 30 cm (12-inch approx.) gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions , in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played.
An ultra-pure sample of uranium-238Uranium-238 is the most common isotope of uranium found. When hit by a neutron, it decays into thorium-234, with a half-life of 1. 41 × 1017 seconds (4. 46 × 109 earth years). Around 99. 284% of naturally occurring uranium is uranium-238, which has a half is electroplatedElectroplating is the use of a solution of a metal salt, and an electrical direct current to coat an electrically conducting item with a layer of the metal making up the metal salt. Electro-deposition is the process by which electroplating is performed. onto the cover. It is intended that analysis of the decay productIn nuclear physics, a decay product also known as a daughter product, is a nuclide resulting from the radioactive decay of a parent or precursor nuclide. Decay products are extremely important in understanding radioactive decay and the management of radios of the uranium will provide a reference for the time of manufacture (in very rough terms - the half-lifeThis article describes the scientific meaning. For the computer game, see Half-Life''. For a quantity subject to exponential decay, the half-life is the time required for the quantity to fall to half of its initial value. Quantities subject to exponential of uranium-238 is around 4.5 billion years).
