All I can think of is alien adolescents reprogramming them to mess with humans. Fake invasion messages, alien memes. Like cowtipoing, but screwing with humans instead
I mean... Can you reprogram Voyager 1? We have a bunch of random polyhedrons from the ancient world and we don't even know what the hell they are. Our stuff could be so ancient compared to an alien that they are just as baffled by it as we are of those polyhedrons.
They might not even be able to understand the simple pictorial instructions for playing the audio on the golden record Voyager carries.
There's a novel titled Glasshouse, by Charles Stross, where members of a far future civilization sign up to live in a simulated mid-20th century town. At one point the protagonist disassembles a flashlight and discovers that it's just a flashlight-shaped case containing a small wormhole whose other end is in close orbit around a star. No one knew how to make an LED or incandescent bulb, or understood enough about early electronic components to hook one up to a switch and a battery. It was easier to make a wormhole generator and stick it in a metal tube.
Any alien species that is aware of our satellites is so technically superior to us they wouldn't bother. The James Webb Telecope is our best, but we still aren't certain we've named all the planets in our own solar system.
I mean, sure, technically. They'd have to know English, know the programming language that was used for the probe, know the transmission frequency that the probe accepts, know the boundaries and limitations of the probe so that they don't actually force any errors, and presumably would need to crack the encryption preventing anyone else from reprogramming Voyager 1. They'd also either need to be able to generate incredibly strong radio waves through space in order to transmit their code, or they'd need to be close enough to us that we'd be able to detect their presence.
While that's all technically possible, the odds of it happening are pretty low.
Crack encryption from the mid 70's? If there even is any on the Voyager command signal, I couldn't find a reference to any. But if there is, I'd think modern computers are up to the task.
They’d also either need to be able to generate incredibly strong radio waves through space
My guess is that THIS is the actual security feature.
Not to mention... who would even want to? There's nothing to gain except slight infamy, if you could even prove you were behind it.
Did you fall in the shower and hit your head before thinking this? It's so incredibly dumb on multiple levels.
Voyager 1 isn't even outside our solar system yet, at the moment of writing this it's close to 15,200,000,000 miles from our sun, that's 0.0026 light years.
the closest star to ours is Proxima Centauri, about 4.2 light years away, part of a triple star system called Alpha Centauri. It would take Voyager 1 over 16,000 years to reach it if it was going there, which it's not.
The first "close" (1.6 light-years) flyby of a star Voyager 1 will have is of Gliese 445, which is 17.1 light years away from us, in 40,000 years.
You seem to think that other stars are right at the edge of our solar system or something, that's the only thing I can come up with that makes your post make any sense. Just because Voyager 1 is far away from us doesn't mean it's close to anything else. It has barely moved in astronomical distances, we will continue to be the closest thing to it for another 20,000 years.
Yes, one entity being able to reprogram one piece of tech definitely means another entity is able to reprogram every other piece of tech that is slightly related.
Probably not all of them. The Voyager probes were launched in the 70s and they don't exactly need much encryption because they can only be programmed by someone with a massive transmitter.
