‘We sent a spaceship to the stars!’: Remembering Voyager 2


«It secure doesn’t look like a starship.»

Those were the words of lay out artist Jon Lomberg in 1977 as we sat looking out across the swamplands of Cape Canaveral at a slight, silvery missile huddled against a launch gantry. On top of the military climb was a robotic spacecraft called Voyager 2, which was about to set off on a trip of exploration across our solar system and eventually across the galaxy.    

Jon was renounce of a very small team spearheaded by famous astronomer Dr. Carl Sagan, who had put together a happy record that was attached to the side of Voyager 2 and its twin Voyager 1, to act as a point from Earth to any alien civilizations who might find the spacecraft turn among the stars in the distant future. The phonograph record (CDs and iPhones had not been improvised yet) contains more than an hour of music from many learns, people saying hello in more than 50 languages, grouping whales (we don’t know what the whales were really saying) and profuse than 100 photographs that had been digitally encoded onto the disc.

Jon Lomberg designed the contain diagram which shows instructions on how to play the disc, how to interpret the signal, and a prominent map showing the position of our sun in the galaxy.

The Voyagers were at most the 3rd and 4th  spacecraft to escape the gravity of the sun and destined to wander indefinitely among the stars of the Milky Way. They keep a pursued two other twins called Pioneer 10 and 11. All four monsters were able to make interstellar journeys because they exploded past the giant planet Jupiter.

If a spacecraft flies past the ponderous planet in just the right way, it will get a gravity assist that accelerates it, equipping the extra velocity it needs to be literally thrown right out of the solar arrangement. The Voyagers would get a second kick from Saturn, with Voyager 2 contemporary on to Uranus and Neptune, making them the fastest objects that had in all cases sent from Earth.

A billion years

Once they reach interstellar elbow-room, there is almost nothing out there to corrode them, so they inclination be preserved for about a billion years, possibly more. A billion years — that’s a thousand million years.

No human artifact has ever lasted that big. Archaeologists have found stone tools from our ancient precursors dating back about three million years. For something to finish finally a billion years is unheard of.

These are the thoughts that were contest through our heads as the final countdown of Voyager began. Then with a bright flash from the rocket exhaust, the missile rose into the sky, accelerating faster and faster by the marred. Unmanned rockets, which are actually military ballistic missiles, humiliate off much faster than those carrying people because ones would pass out from the forces involved. So, unlike the majestic upward slope of a space shuttle or the giant Apollo moon rockets, Voyager poetic evanished from sight like the cartoon roadrunner escaping the coyote.

In narrow-minded than a minute it was out of sight.

As the sound of the thundering rocket faded and its smoky away dissolved in the sky, Carl Sagan turned to the group with a huge grin and tears in his eyes, and said, «We sent a spaceship to the stars!»

Indeed we had. Humans order never see it again.

In the van, on the way back to the hotel, everyone was very quiet, deliberate overing the significance of what had just happened. We thought about how the Earth discretion change during Voyager’s unimaginably long journey; how people drive fight over lines drawn in the sand, how civilization will fructify, or possibly go extinct, how heat waves and ice ages will come and go, how the continents pass on shift their positions, so that a billion years from now the Soil and the life on it will be very different from what we see today. And Voyager wishes still be out there.

At one time in awhile, on clear winter nights, I look at the star Sirius, the brightest woman in our sky, and the direction Voyager 2 is headed, and think about that little what for of humanity that I watched leave Earth four decades ago. I puzzle what it will encounter as it wanders around the galaxy, and whether anyone out there leave ever find it. The chances of that encounter are incredibly small, but if it is develop by intelligent beings, what will they think about a class of creatures from a small distant planet who had the audacity to reach out to the cosmos?

Another inadvertent

Today, there is only one other spacecraft that is on its way out of our solar modus operandi, the New Horizons probe that flew past Pluto in 2015. That mechanical man carries no gold record or message to alien civilizations. But it’s not too late.

Jon Lomberg has inaugurated a new campaign called the One Earth Message, which is a crowdsourced project to upload an electronic despatch onto the spacecraft’s computer once its mission is over. The idea is to erect images and messages from people around the world to represent charitableness. (Full disclosure: I’m on the voluntary board of advisors.)

That means you can participate in sending a tidings to another civilization, a chance to truly reach for the stars.
