Voyager 2
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: After Voyager 2's flyby of Neptune, NASA formally renamed the entire project (including both Voyager spacecraft) the Voyager Interstellar Mission (VIM). Some year before 2030, Voyager 2 is expected to cross the heliopause-the outer boundary of the vast region of space dominated by the solar wind and the sun's magnetic field-and reach interstellar space. In that sense, it can be said that the spacecraft will be able to sample what space is like beyond our solar system. (If we define the solar system as the sun and everything that primarily orbits the sun, however, Voyager 2 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.)

As the spacecraft's power supply dwindles, it will need to begin shutting down its instruments in 2020. Sometime in 2025 or after, there will be insufficient electricity to power even one instrument, and Voyager 2 will continue its eternal journey among the stars in silence.

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.
