Voyager Space Probes – the most remote cameras in the universe – are powered by 44 years of space travel.
Voyager 1 and 2 have made it deeper into Space than anything man has ever done in history. Both were introduced in 1977 to mark the particular order of planets in our solar system.
The Voyager system has been able to exploit the cosmic interaction in which Jupiter, Saturn, Uranus, and Neptune are all arranged so that probes can visit each of these planets in their one-way orbit from Earth.
The probes captured images of Jupiter clouds, discovered new phenomena such as the volcano on the moon Jupiter Io, and investigated Saturn rings.
NASA has previously stated that Voyagers were “destined – perhaps forever – to roam the Milky Way.” But radioactive plutonium probes lose power by about four watts a year.
Launched 45 years ago, NASA has decided to reduce its impact on research that could extend its lifespan by a few more years until about 2030. The first speculation was that the Voyager expedition would take only four years.
“We’ve made a 10-fold warranty on black items,” Ralph McNutt, a Johns Hopkins University Applied Physics Laboratory physicist, tells Scientific American.
The primary purpose of the probes was to fly Jupiter and Saturn, which they did in two years. After completing their first project, they continued deep into Space and sent pictures of our solar system far and wide.
In 1990, Voyager 1 restored the landmark image of “Pale Blue Dot,” depicting the Earth against a massive universe that has taken up 3.7 billion miles from our Sun.
In 1998, Voyager 1 became the most artificial object in Space – 6.5 billion miles from Earth. According to a NASA live tracker, the probes are now 12 billion and 14.5 billion miles from Earth.
After 2030, Voyager is likely to lose contact with Earth, but both devices have a 12-inch, gold-plated record carrying information from Earth. This includes 115 pictures, greetings in 55 languages, sounds of the wind, rain, heartbeat, and 90-minute music.
