Voyager 1 passing out of the Solar System on August 25th was a epochal event, a fact recognized by a few quality journalists, although you'd never have known it from the limited attention it attracted from the mass media as a whole. But think of it - a man-made device has LEFT our star system and is travelling into the Great Beyond! In 40,000 years, all being well, Voyager One will meet another star. Imagine time travelling back a hundred years and trying to get acceptance of a fact so far beyond the comprehension of any of our forbears.
Back in the late 1970s when the two Voyagers were launched many of us still thought that John Kennedy had it right in saying that entering space was the next great task for our civilization. Pundits like Arthur C Clarke in his Century stories assumed that well before today humans would be up there making fabulous discoveries. Yet somehow there was not nearly enough gas in the tank for that adventure.
Instead we find ourselves a half century on without any compelling vision of our future other than predictions that are highly dystopian, and where we overcrowd a warming and increasingly polluted world in which the social order is threatened to breaking point. The light has gone out above a picture where intrepid and optimistic humans sail away to see what lies beyond.
The way things are now, within our lifetimes we might see a few very expensive robotic space vehicles mining nearby asteroids for rare metals and one or two additional thinly-manned space stations operating, perhaps eventually even one on or around Mars. But the grand dream, so much beloved of SF writers, of 'generation star-ships' that travel bravely to found human colonies out on ‘The Final Frontier' seems to have died with Gene Roddenberry.
It is all the more important then for us to honour a little unmanned and primitive star-ship which is expected to continue sending us news from space even when I'm no longer. So sail on, brave Voyager, and keep the dream alive in your own small way
