voyager probe
Images depicting either Voyager 1 or Voyager 2, interstellar probes built by NASA as a part of the Voyager Program and launched in 1977. The twin probes were launched to take advantage of a favorable planetary alignment that occurs every 175 years which allowed the probes to swing by multiple planets on their journey to beyond the solar system. Voyager 1 flew by Jupiter and Saturn and Voyager 2 flew by Jupiter, Saturn, Uranus, and Neptune. Voyager 1 entered into interstellar space in 2012, making it the first spacecraft to do so.
The voyager probes had a Golden Record placed on them, a phonograph record that contains sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them. The records are a time capsule.
