The Voyager spacecraft, comprising Voyager 1 and Voyager 2, launched on September 5 and August 20, 1977, respectively. Designed primarily for planetary exploration, the missions significantly advanced space exploration by providing unprecedented data about the outer planets of the solar system, including Jupiter, Saturn, Uranus, and Neptune. Voyager 1 became the first human-made object to enter interstellar space, transmitting valuable information about conditions beyond the solar system. The spacecraft carry golden records containing sounds and images depicting life on Earth, intended as a message to any extraterrestrial intelligence. Together, they represent a monumental achievement in human discovery and scientific inquiry.
