Pioneer Plaque

In the previous entry, I mentioned about one particular president who sent something into space in hopes that alien lifeforms would receive it. Okay, so after an arduous search on the internet, I finally found what I was referring to.



The Pioneer Plaque are a pair of gold anodized aluminum plaques which were placed on two spacecrafts, the Pioneer 10 and the Pioneer 11 in 1972. The unique thing about these plaques were that it contained pictures of mankind (nude figures of a man and woman) and other symbols that provided information about the spacecraft and where it came from.



Another item that was sent into space on board the Voyager spacecraft in 1977 was the Voyager Golden Record that contained sound and images that showed human life and the cultures on Earth. It is a time capsule made for intelligent lifeforms to decipher, seen as a form of communication between Earthlings and extraterrestrials.

As said by U.S. President Jimmy Carter,

"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."

The interesting thing about this time capsule would the contents contained within it; 115 images and a variety of sounds including surf, wind, thunder, animal calls, even printed messages from Jimmy Carter. Images are coded in analog form, and spoken greetings in 55 languages are included in the record. This record is made of gold-plated copper and also contains a sample of uranium on the cover, considering that uranium has a half-life of 4.51 billion years, it is hoped that any lifeforms encountered in the far future would use it to find out the age of this record.

For more information, type any of the highlighted text into Wikipedia... As I got my information from that website.

Here are some of the 115 images that can be found in the record.
