Historical Context

NASA's Voyager program began after it was discovered a 'once in a lifetime alignment' would allow a spacecraft to fly past some of the solar system's planets using their gravity.

The mission, managed by California's Jet Propulsion Laboratory, launched Voyager 2, the first of two spacecrafts, from the Kennedy Space Center in 1977. Although launched second, it was calculated that Voyager 1 would reach Jupiter and Saturn first, which it did in March 1979. Voyager 2 followed in July 1979. Their findings include the discovery of a number of new moons, with evidence of volcanic activity on Jupiter's moon Io and the storm at the center of Jupiter's red spot.

Voyager 1 passed by Saturn in November 1980, Voyager 2 in August 1981. Voyager 2 went on to become the first spacecraft to fly close to four planets, flying by Uranus in 1986 and Neptune in 1989. After this their cameras were turned off to preserve power.

In 2004 Voyager 1 crossed the termination shock, where the solar and interstellar winds meet before becoming the first human-made object to reach interstellar space in 2012. Voyager 2 followed and reached interstellar space in 2018.
