Voyager 1
Voyager 1 Mission to Jupiter Voyager 1 Mission to Saturn Voyager 1 Mission to Our Solar System Voyager 1 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 1 targeted Jupiter and Saturn before continuing on to chart the far edges of our solar system.

Accomplishments: In August 2012, Voyager 1 became the first spacecraft to cross into interstellar space. Here Voyager can 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 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years).

Fast Facts
Voyager 1 Facts Voyager 1 is speeding along at about 57,600 kph (35,790 mph) -- fast enough to travel from the Earth to the sun three and a half times in one year.

Both Voyagers carry a gold record "greeting to the universe" (right) containing sounds and images selected to portray the diversity of life and culture on Earth.

Voyager 1 is escaping the solar system at a speed of about 523.6 million km per year, or about 1.4 million km per day and is now in interstellar space (as of Aug. 2012).

Even at this tremendous speed, Voyager 1 will take at least 14,000 years (and maybe twice that or even longer) to emerge from the Oort cloud.

Did you know that the record is a 30-cm gold-plated copper disc? Together with a needle and playing instructions, it is mounted on the body casing and on it are recorded natural Earth sounds, 90 min of music, 115 pictures, and greetings in 60 languages.
