So, what was the "satellite feed" mentioned in the story? Was it a regular TV broadcast, or something more internal distributed by NASA?
I just looked it up, they had something called Neptune at Night that broadcast from midnight to 9AM. I probably caught it in the mornings before school.
It's kind of wild to think about: we might end up collapsing our own civilization before we ever make it beyond our solar system.
At this point, I suspect the next real explorers won't be us, but probes carrying intelligent machines..our robotic descendants venturing where we can’t.
Short terms issues preventing long term gains.
I've never felt this impulse. To me it's like saying the Earth is 8,000 miles thick but we all chose to live within just a few feet of the surface.
Given what I see in the past 15 years, I don't particularly see that as a problem, honestly.

Voyager Will Reach One Full Light-Day Away From EarthWe don’t understand quantum mechanics and we don’t understand gravity. There’s no reason to assume that we won’t find ways to travel the universe, e.g. by manipulating space time. We just don’t know what we don’t know.
If you had to bet based on past achievements, humanity will find a way. Our job is to push the limits as much as we can and build a foundation for future generations.
What if that's exactly what will cause our extinction, you don't know what you don't know am I right ?
> It will take about 300 years for Voyager 1 to reach the inner edge of the Oort Cloud and possibly about 30,000 years to fly beyond it.
When will we need more resources than exist here? We'll be mining the sun to run future simulations. Do we need more compute? Seems like we'll just stay inside.
Most life is probably similarly bound up to their origin. That and life is hard by many, many, many hard steps. Earth life is nearly 30% the age of the universe and it took us this long to get here.
It'd be near impossible for aquatic life to have an industrial revolution without aqueous chemistry control. Can't do that when you're stuck inside water. It's also hard to evolve reasoning when you can't see far ahead. Little evolutionary pressure on reasoning over time and distance.
And it's hard to leave water. You need to evolve new eyes and lungs to live on land. And then you need an energy source like O2, which tends not to stick around.
So many reasons.
The distances of space are certainly one holding us back now.
If it’s the patterns that matter, do you think it’s actually impossible for those patterns to be transmitted across interstellar distances? Just like a cup of ocean water is packed with DNA, it’s at least conceivable that what we call “cosmic background noise” could, in principle, hide extremely compressed life-patterns that only an advanced civilization could recognize and reconstruct back into something we’d meaningfully call “alive.” And of course, the more efficiently you code that information, the more it statistically has to look like random noise.
Not saying this is likely -- just that if the essence of life is informational rather than chemical, "traveling" could look very different for any life that is suitably advanced.
I think it was the book Pale Blue Dot by Carl Sagan where he hypothesized aliens living in Venus and how they wouldn't be able to see the stars and other planets because their atmosphere is too thick to see through with visible light and also their perpetual, opaque cloud cover made of sulfuric acid.
He described how everything would change if they managed to just escape their planet for the very first time and see a new world out there that they never even imagined existed. A world more vast and complicated than their brightest minds could have ever thought of.
Damn, I might need to read some Carl Sagan again!
Those are thousands of times more hospitable than outside earth.
You also breathe a nitrogen-oxygen-hydrogen mixture, and have a body that is built to walk around at 1g on a planet between 0-100 degrees F.
That doesn’t seem to bother people.

Humans like to explore. We've populated the globe from our starting position in East Africa.
When we look to the skies, beyond our own galaxy, and into the early history of the universe, we are seeing a world that will never get to explore first-hand. Humans like to explore.
Obital mechanics are a funny thing however. You see this with the complicated BepiColombo trajectory to Mercury [1] that requires multiple passes on Venus. Mercury orbits at ~48km/s (compared to Earth's 30km/s). Fun fact: the escape velocity of the Sun is 42km/s so it's easier to leave the Solar System than intercept Mercury.
One difficulty is there aren't large gas giants to slingshot or brake around.
Uranus's orbital velocity is ~6.8km/s so it's both really far and requires a ton of delta-V to slow down to intercept.
Anyway, I digress.
So Voyager 1's speed seems to be ~17km/s, I guess relative to the Sun. People talk about the time required for interplanetary (let alone interstellar) travel but we can do much better than this with relatively near-future technology.
We need a whole bunch more Earth-orbit space infrastructure and industry to do anything, really. Lower launch costs in particular. I think this future is orbital rings [2]. This would revolutionize getting stuff into orbit but also launching vehicles to other planets. Basically you accelerate on the inside of the ring at ~2G with magnetic levitation to counter the linear momentum. You can reasonably get ~15km/s with this, adding to the EArth's 30km/s ideally so even without fuel you can get to ~45km/s.
Everyone.
Times have changed somewhat!
We are going to lose it before long i wonder if it will be possible to find it on a future date in theory.
It’s gravitationally bound to the Milky way so it’s going to keep wandering into and out of star systems for a very long time. We’re talking a large multiple of the age of the universe meanwhile plenty of space rocks show encounters with other space rocks on a vastly smaller timescale. If nothing else it’s got decent odds of being part of the star formation process. Stars are ~10% of the milky way’s mass and star formation is going to continue for a while.
The chance of impacting anything larger than that is internal, same as an encounter with another star. In 40,000 years it will get to within 1.6 light years from a star, that’s such an unimaginable distance it’s irrelevant.
In 100 million to 1 billion years you may not be able to recover audio from the golden record, but until that point they will be lasting remnants of a civilisation long gone, and never be encountered.
Voyagers will only impact a few thousand kilograms of material before all stars die out in 10^14 years, it will still be an object after the final stars fade.
The biggest risk to voyager now is if proton decay is a thing, or if a civilisation deliberately seeks it out, which seems very unlikely given how many natural lumps of iron int he 1 ton range flying through interstellar space.
Look at the metal that we routinely dig up in the hostile environment known as 'Earth' and which wasn't particularly designed to be long lasting. Voyager is just that: designed to last for a really long time. At a minimum several millennia, though of course by that time the electronics will no longer function, and not because they no longer have power but simply because they have degraded due to their rather more sensitive nature than the rest of the craft.
It will be sitting at something like -450F. Could it really lose form!? Is the idea that all the phonons could converge to one point, shifting an atom of metal (which will happen infinitely with infinite time)? Maybe with random photons/hydrogen/whatever "continuously" adding energy?
Neat.
Not sure about “melting” into an amorphous mass, I guess in theory the probes gravity could do that, but I would imagine even the tiniest force would disturb that and dissipate it.
This is read as "near zero" rather than "no chance". "Expected" is a word of uncertainty.
I think the rough napkin math would be: take the volume that the probe will sweep through and multiply it by the volume of matter in the universe/volume of the universe.
My favorite conspiracy about aliens is that the nuclear explosion testing in the 50s had an observable effect and there’s some documented proof of maybe something was watching us: https://www.astronomy.com/science/did-aliens-watch-1950s-nuc...
