These Are Interstellar Times

interstellar travel, voyager 1 beyond heliosphere, first in space exploration, conscious shift, NASA rocks, amazing news,


The most epic science fiction fantasy is coming true. For the first time ever a human-built vehicle is leaving the entire solar system behind. This is huge. The daily news cycle has barely mentioned it in passing. Most people on this lovely blue-green planet have no idea what our species has accomplished.

Six months ago experts predicted say it could happen any time. Now it has. Voyager 1 has flown beyond the heliosphere, the bubble-like region dominated by the Sun and its solar wind. We’re going where we’ve never been before. I’m talking interstellar. That’s defined as “the space between stars.” The whole futuristic thing? It’s here.


We’re making science history with 1977 technology too. That year our species toddled toward greater innovations. For the first time optical fiber was used to carry telephone traffic. New technology debuted, such as Commodore PET, Tandy TRS-80, and Apple II series computers. The Atari 2600 was released. And (coincidence?) Star Wars opened.

space exploration, big news in space,

Voyager spacecraft sent back 52,000 images of Jupiter. (Image:

Voyager spacecraft are powered by computers with 80 kilobytes of memory, using software without data storage capability. (They rely on relics known as tape recorders.) Despite weak signal power, information is sent from both Voyagers daily. So far that totals five trillion bits of scientific data.

Over time some of the instruments have been turned off to save energy but not before both Voyagers sent back remarkable, never-before-seen images of our solar system. Thanks to Voyager drive-bys we more fully understand the far-off worlds of Jupiter, Saturn, Uranus, and Neptune. Science is still mulling over the data.

Then in 1990, as Voyager 1 moved ever farther from us, Ground Control directed the craft to turn around so its cameras could photograph the planets. From that vast distance, Earth appeared only as a point of light in the darkness. The image was titled “pale blue dot.” It inspired Carl Sagan to give a lecture and later to write a book titled Pale Blue Dot: A Vision of the Human Future in Space. In it he wrote,


The Voyager crafts weren’t actually intended to do more than a planet hop for five years. But as we’ve seen, those unsung NASA types take their jobs seriously. They designed the probes to do a lot with a little. The program weathered funding cuts, even a Bush-era threat to end the entire program, and as money trickled in NASA reprogrammed the spacecraft to keep going.

The total cost of the Voyager missions from planning in 1972 to today (including launch vehicles, power source, and tracking support) comes to $865 million. This equals about eight cents per U.S. citizen per year. To put it another way, we’re cracking interstellar space for a fraction of the $6 billion the 2012 U.S. political campaigns were estimated to cost.

The Voyager probes carry more than 70′s era equipment. Before the spacecraft were launched, Carl Sagan chaired a committee to determine what message we humans should send to beings who might eventually come across the Voyagers. That’s why each Voyager carries sounds and images from earth on gold-plated copper disks, electroplated with uranium-238. They’re called Golden Records. They include diagrams of DNA, maps of the Earth, greetings in 55 languages, sounds like a chimpanzee’s call, images of people engaged in daily activities, and music such as blues by Blind Willie Johnson and a concerto by Bach. One of the messages is by President Jimmy Carter, which says in part,


Here’s to Voyager 1. Eleven billion miles from the Sun and now beyond our heliosphere carrying determination and goodwill.

Here’s to humankind, achieving wonders even if we too rarely pause to notice. Let’s have another beautiful shift in consciousness, as we did when the luminous image of Earth seen from space was photographed in 1972 awakened us to a worldwide ecological movement. It’s time to shift again. We are co-participants in a much larger and more amazing story.

  1. Well, unfortunately, this is not the 1970’s anymore, and all this wonderful science plus a buck and a half will get you a cup of coffee just about anywhere down this block, Don’t get me wrong: I’m in favor of the science, but the degradation of the US educational system is so systemic that 88% of Americans now believe in angels and devils, about what the mediaeval average in Europe was. So the once-exciting space-stuff just isn’t there for a non-scientific America any more. Pity. Your country could have done so much, but has now retreated and ceded space to the Russians and the Chinese. Tragic.
