Celebrate Voyager's 40th Anniversary By Beaming A Message Into Outer Space (nytimes.com)

Long-time Slashdot reader Noryungi writes: NASA will celebrate the 40th anniversary of the launch of the twin Voyager probes next month. So let us celebrate both the probes and the people who are still working on them, and nursing them in their final years.
The New York Times fondly profiles Voyager's nine aging flight-team engineers who "may be the last people left on the planet who can operate the spacecraft's onboard computers, which have 235,000 times less memory and 175,000 times less speed than a 16-gigabyte smartphone." NASA reports that now "Voyager 1 is in 'Interstellar space' and Voyager 2 is currently in the 'Heliosheath' -- the outermost layer of the heliosphere where the solar wind is slowed by the pressure of interstellar gas. " But the Times notes that the probes "are running out of fuel. (Decaying plutonium supplies their power.) By 2030 at the latest, they will not have enough juice left to run a single experiment."

NASA is now inviting the public to submit positive messages to be considered for beaming into space on September 5th -- the 40th anniversary of Voyager 1's launch. "Messages can have a maximum of 60 characters and be posted on Twitter, Instagram, Facebook, Google+ or Tumblr using the hashtag #MessageToVoyager," until August 15th, after which humanity will vote on which message should be sent.

      First, the Voyagers did actually have a small amount of fuel for attitude adjustment and maneuvers around the planet. You know, the mission they were actually designed for. That fuel is pretty much gone now.

      And no, solar power is useless where these probes operate. Solar panels would actually even have been useless as a power source in their actual mission, there is a reason that Juno is the first probe sent to Jupiter (the innermost of the "outer" planets, the gas giants) to use panels instead of RTGs, because only now we not only have managed to create solar panels that can output sensible amounts of energy at that distance to the sun, but we also managed to build electronic devices that can run on power requirements that are 3+ orders of magnitude smaller.

      We are after all talking about probes that were launched four decades ago.

      And finally, these probes were supposed to take a look at Jupiter and Saturn (and Uranus and Neptune in the case of Voyager2). And that's it. Anything past that is bonus. And these two probes have been handing out way, WAY more information than what could possibly be dreamed of.

      The problem we have is not that we can't go anywhere, or send another probe, or don't have the technology or know-how. It's that nobody wants to pay for it any more. You can't do much about that problem without finding someone willing to pay.

      The planets only align for the "grand tour" gravity boost the Voyager probes got once every 175 years. And they contribute a lot more to slingshoting the probes out of the solar system than chemical rockets do. Unless we get a massive breakthrough in some other form of propulsion there's not much point in trying again until 2151. Not that we actually expect to find much of anything outside the heliosphere, Voyager 1 is 20 light minutes out and it should be pretty empty for the next 4.3 light years. Since the slingshot won't get much better than for Voyager we really need a different form of propulsion to go interstellar. Unless we can wait tens of thousands of years, but then technology might improve a bit in the meantime.

At the point where they will probably go silent they will have been in transit for 53 years, and 50 years since they got their full energy kick - the largest any probes have ever received due to a double gas giant slingshot manuever*. There are no new super high-velocity missions even being floated that I can find, so it may be decades before anything of similar or greater speed is launched.

    Future probes beyond Saturn will probably be orbiters instead of fly-bys, and all such trans-Saturnian missions will probably use advanced electromagnetic propulsion (ion, plasma, maybe even solar sail) that is still being developed or in the early stages of roll-out.
