Voyager 2 Mission to Jupiter Voyager 2 Mission to Saturn Voyager 2 Mission to Uranus Voyager 2 Mission to Neptune Voyager 2 Mission to Our Solar System Voyager 2 Mission to Beyond Our Solar System

Goals: Voyager 1 and 2 were designed to take advantage of a rare planetary alignment to explore the outer solar system. Voyager 2 targeted Jupiter, Saturn, Uranus and Neptune. Like it's sister spacecraft, Voyager 2 also was designed to study the edge of our solar system beyond the planets.

Accomplishments: Voyager 2 is the only spacecraft to study all four of the solar system's giant planets at close range. It is now exploring the outermost reaches of where the solar wind and the sun's magnetic field dominate space. In September 2007, it crossed the termination shock (where the speed of the solar wind drops below the speed of sound) at 84 AU (about 13 billion km from the sun, more than twice the distance to Pluto). Since then, Voyager 1 has been operating in the heliosheath environment, a region about 40 to 50 AU (3.7 billion to 4.7 billion km) thick where the solar wind mixes with the interstellar wind.

Fast Facts
Voyager 2 Facts Both Voyager spacecraft carry a greeting to any form of life. The message is on a 12-inch gold-plated copper disk (right) containing sounds and images that portray the diversity of life and culture on Earth.

One of the musical selections on the Voyager gold record is Chuck Berry's 1950s hit Johnny B. Goode.

Voyager 2 is escaping the solar system at a speed of about 3.3 A.U. (495,000,000 km) per year.

Voyager 2 is the only spacecraft to visit Uranus and Neptune.

A 30-cm gold-plated copper disc, together with a needle and playing instructions, is mounted on the body casing. On it are recorded natural Earth sounds, 90 min of music, 115 pictures, and greetings in 60 languages.

It is departing our solar system in a different direction than Voyager 1.
