From the current 'Short Schrift" on my home page, http://www.rogerandfrances.com/ (where you'll find a pretty picture of a valve radio and an M9 to accompany it):
The space probe Voyager 1 was launched in 1977. It is now more than 10 billion miles from Earth. Last time I heard, it was still broadcasting data from the edge of the solar system.
This is a poke in the eye for those who airily dismiss any piece of electronic wizardry as "obsolete" or worse still "worthless" once it is more than a few years (or a few months) old.
It would almost certainly be possible to design something a good deal cleverer today, though getting it built to the same standard might be more problematic, and the funding would be even more difficult. Besides, if you launched it tomorrow, it would still take decades to get to where Voyager 1 is today. And so, young NASA scientists are still using a satellite that was old when they applied to university. It's still doing what it was designed to do, and doing it very well.
One day, no doubt, it will either fail or go beyond the range of our ability to detect its signals. But right now, it works. If something does its job, then it does its job, much as (say) an 18-megapixel camera goes on delivering adequate quality for an A3 magazine spread. It doesn't stop working just because something newer is theoretically available. Unlike the brains of those who are besotted with (for example) the latest iPhone, computer, or, yes, digital camera.
Cheers,
