Exploring the Journey of Voyager 1 and 2

The video discusses the Grand Tour mission, which led to the launch of Voyager 1 and 2 in 1977 to explore the outer planets. The Voyagers made significant discoveries about Jupiter, Saturn, Uranus, and Neptune. Equipped with scientific instruments, they continue to send data from interstellar space. Despite power and communication challenges, the Voyagers are expected to operate until 2027. They will eventually travel beyond the solar system, carrying humanity's message into the cosmos.
