Voyager series


 * You may be looking for Star Trek: Voyager.

The Voyager series of space probes were unmanned spacecraft created by the American space agency NASA in the later half of the 20th century. Designed as planetary surveyors, these probes recorded their findings which were later transmitted to NASA. In the event of a probe's malfunction, an operator could access the probe's memory banks by the use of an unique numerical code.

Voyager 6
Voyager 6 was the sixth of the Voyager series. It was believed to have traveled through a black hole and became the source of the machine planet's V'Ger cloud. 

Background
The first two (in real life, only) Voyager probes each contained a of numerous earthly sounds and images, including 6-year-old Nick Sagan (whose father chaired the committee which chose what to put on the record) saying, "Hello from the children of planet Earth".
