The Voyager Program

The twin spacecraft Voyager 1 and Voyager 2 were launched by NASA in separate months in the summer of 1977 from Cape Canaveral, Florida. The mission profile was designed to take advantage of a rare geometric arrangement of the outer planets in the late 1970s and the 1980s.

Over the years, the Voyager probes have returned information to Earth that has revolutionized planetary science.

Voyagers 1 and 2 are identical spacecraft.

The spacecraft are controlled and their data  returned through the Deep Space Network (DSN), a global spacecraft tracking system. Voyager 1 is currently the remotest human-made object. For the past 18 years they have ben probing the Sun’s outer heliosphere.
