I guess it reached the limit of the sky box, there’s nothing running on the simulation after that.
Is there any reason we haven’t built a craft specifically to be slung out of the solar system as quickly as possible?
IIRC Voyager wasn’t built for this, it’s just a bonus that they’re still semi operational.
The planets needed to be in a certain alignment for the Voyager launches to work out like they did. The slingshot only works in one direction (if you go backwards, you lose momentum). Maybe we haven’t seen another such alignment since, or didn’t have a mission ready to launch if we did.
In addition to what others have mentioned, there’s also a problem of communication. Inverse square law is a bitch. It was actually assumed at the start that the limit of the Voyager missions would be communicating with the probes, but improvements in radio technology have kept it going longer.
Information on the heliopause is about the only useful thing we can get from something out that far. It turns out to be a lot more complex than we thought. After that, there’s nothing interesting until you can get to the next star, and our radio technology isn’t up for that.

It seems to me that this would be worth a mission?
It’d be hard to justify a mission on that alone. At least for now. Get space based industry going and then there’s lots of missions that open up.
New Horizons will get there eventually, and from a brief search, it sounds like it could still get back useful data once it’s out that far. NASA will need to keep the communications line funded, though.
Space travel is very expensive and NASA has a very small budget these days.
Back during the space race, NASA could afford to launch multiple missions per year. Now they can barely afford to maintain existing missions and are lucky to launch a major missions every few years. Which is why they’ve moved to buying space on commercial missions, as it’s cheaper to only pay for a spot on a rocket/craft than to pay for the whole thing.
NASA also has to justify its missions to congress. Sending rovers to mars and probes to the moons of Jupiter and Saturn have actual scientific interest and can answer questions about the formation of the solar system, and the viability of life off of earth.
Slingshotting something really fast sounds cool as fuck, but there’s not much data to be gathered there. We’ve also recently beaten the “fastest man made object” record with the Parker Solar Probe, as it’s currently whipping around the sun at ludicrous speeds while it collects data about the solar atmosphere and magnetic fields. It’s moving a lot faster than voyager ever did, as it needs an insane amount of speed to orbit so low to the sun. It’s actually much cheaper, fuel wise, to travel to Pluto than the sun.
So why waste billions of dollars to fling something out into deep space? We have barely even seen all Of the celestial bodies in our own star system, and there’s not much to be learned about the empty vacuum beyond the sun. The only justifiable reason would be to send a probe to another star system entirely. But that probe alone would have to be the largest, most expensive space craft humanity has ever built. It would need to be able to power itself for centuries, have a communication system capable of sending data over interstellar distances, and likely need a way to autonomously harvest its own fuel, as there’s very little point in sending a probe screaming past Proxima Centauri and taking a few hazy pictures of planets as it goes. We’d want the probe to be able to stay in and explore the new star system, and the only way to do that is to have enough fuel to move around an entire system, or create more fuel as it goes. Something like that has never even been tried before, and the risk is high when you won’t know if it worked or not for a few hundred years.
Another important factor with the Voyager probes is that they got their solar escape velocity with the help of a very fortunate alignment of the outer planets that only happens once every 176 years. It was much cheaper to fling something out that far under those conditions, and we won’t see them again until 2153.
I believe there was a case made to chuck something out perpendicular-ish to the ecliptic to see what shape the heliopause and solar wind take out there, what gases are kicking around etc. Maybe check out one of the high inclination objects kicking around out there as they tend to be odd ones. Almost all exploration has been done in-plane for obvious reasons.
Commercial launch providers have made launching everything way cheaper, so I can see an agency doing this one someday even if it has to take a pile of gravity assists from the sun. As a bonus you also get a new Voyager traveling in a new direction.
I also can see a lot of people being confused as to why it couldn’t take pictures of the solar system from up there that look like the textbooks… Possibly creating a whole new generation of flat-earth-esque conspiracies lol
I want them to actually chuck a handful of small spacecrafts as far as they possibly can in orthogonal directions, then have them take parallax images for the nearest pulsars we don’t have direct distance measurements of. It would be nice to push back the sphere of distances we’ve measured that way.
It’s going to be like that Star Trek episode where they find Voyager and it’s evolved and achieved sentience.
Is it possible that cosmic rays beyond the heliopause have damaged (bit-flipped) the radiation-hardened circuitry on board the spacecraft? That might cause it to start jibbering nonsense.
That’s very likely what happened. The problem is that the control board that manages communications is so old that nobody can find any documentation on how it works, so they can’t even begin to figure out a fix.
Everyone involved with that project is also probably dead.

Literally, the FIRST sentence of the article is talking about someone who’s been involved with Voyager I from the start. Yes, the project has outlasted many of it’s original engineers, but to say, “Everyone involved with that project is also probably dead,” for a major mission that launched 46 years ago is obviously untrue.
There are a number of possibilities. We likely will never know what actually happened. A bit flip would be bad, but potentially fixable. If they can somehow force a reset. It could also be simple component failure, a bad capacitor, in the wrong place, and your computer goes haywire. Ditto for mechanical damage. A grain of dust, hitting the wrong point could cause a cascade of problems.
The backup systems are long dead. The fact they’ve managed to extend the mission life by 41 years is quite incredible. It was never expected to last this long.
God speed V’ger!
Crazy that after all this time we can still communicate with Voyager 1. Even though it is babbling back now.
That’s actually not all that hard. They just have to blast it with a radio signal strong enough from Earth for it to hear and they have to have really big dishes on earth in order to hear it.
As an electrical engineer who dabbled in RF in school, that sounds supremely difficult.
Yeah, it’s most definitely not easy. Thankfully though, high frequency devices like that are very small wavelengths and therefore gain can be achieved with decently small antennas. The higher the frequency, the shorter the wavelength, and the shorter the wavelength, the smaller the antenna needed to receive it. Or a big antenna can hear it from further away, since it has a big collection area.
