Voyager 1, more than 35 years of service

Voyager 1's travel is amazing. It is the furthest man-made object and was launched on September 5, 1977. In November 2012, it reached an astonishing distance of 123 AU, with 1 AU being the distance from Sun to Earth (roughly 150 million kilometers). Voyager 1 is on the brink of reaching interstellar space, thus leaving the Solar System.

The initial goal of the Voyager 1 was a flyby of Jupiter and Saturn, to learn more about those planets. Those goals were completed in 1979 and 1980.

Voyager one has a speed of 17,26 km/s, which is also a record for a man-made object.

Voyager 1 has taken some amazing photos over time:
