40 Years of Mankind's Messenger to the Alien

The US spacecrafts Voyager 1 and Voyager 2 were launched 16 days apart in August and September of 1977. Both the missions took advantage of a once-in-175-year alignment of planets that allowed between them to visit all the gaseous planets of the solar system. 

PBS (The Public Broadcasting Service), n American public broadcaster and television program distributorlast month released a documentary to commemorate the 40th anniversary of the Voyager missions, The Farthest: Voyager In Space, which can be streamed online.

Here’s the network’s writeup of the event:

The twin spacecraft—each with less computing power than a cell phone—used slingshot trajectories to visit Jupiter, Saturn, Uranus and Neptune. They sent back unprecedented images and data that revolutionized our understanding of the spectacular outer planets and their many peculiar moons.

Still going strong four decades after launch, each spacecraft carries an iconic golden record with greetings, music, and images from Earth—a gift for any aliens that might one day find it. Voyager 1, which left our solar system and ushered humanity into the interstellar age in 2012, is the farthest-flung object humans have ever created. A billion years from now, when our sun has flamed out and burned Earth to a cinder, the Voyagers and their golden records will still be sailing on—perhaps the only remaining evidence that humanity ever existed.

More than 20 billion kilometers from home, Voyager is still yielding terrific science as it battles through the last fringes of our star system.  Voyager was launched on September 5, 1977, a few weeks after its sister scout Voyager 2, and the pair carried out a magnificent tour of all the giant planets—Jupiter, Saturn, Uranus and Neptune.

Afterwards, their missions were reconfigured so they would fly to the edge of the Solar System, and then beyond, into the utter unknown.

Speeding outwards at more than 17 kilometers per second (38,000 miles per hour), at a distance from where the Sun appears the size of a dot, they bear messages for any passing extraterrestrial.

They are "the two most distant active representatives of humanity and its desire to explore", says NASA.

There is also a 30-centimetre (12-inch), gold-plated copper record (, along with a cartridge and a needle to play it with.

The record holds 115 images of  life on earth, recorded in analog form, and a variety of sounds and snatches of music, from singing pygmy girls, Mozart and Bach to Javanese gamelan and Chuck Berry playing "Johnny B. Goode".

In the absence of solar energy in deep space, the two Voyagers are powered by long-life nuclear batteries.

In 2025, the batteries will die and their voices will be stilled forever. But the two probes will carry on their mission, to whatever strange fate awaits them.

NASA is celebrating the anniversary with a set of free, beautifully designed posters.
