Voyager's 40th Anniversary

In August of 1977, the first of two identical robotic probes was launched from Cape Canaveral, Florida, bound for our outermost planets and beyond.

They discovered two dozen new moons, discovered active volcanoes on Jupiter’s moon Io, took a famous “family portrait” of our solar system, and much more. Voyager 1 recently became the first spacecraft to leave the heliosphere and enter interstellar space.
