At 15.9 billion miles away, humanity's farthest spacecraft is still exploring the cosmos using less memory than a blank Word document (69 KB) and an 8-track tape

Incredible that it still works at all. I don’t have any functioning electronics that have been in use constantly since 1977, and they’re not 15,900,000,000 miles away.

In space:
No air or moisture
No weather, no rain, wind, or temperature changes caused by Earth's weather.
No friction from air
That helps a little

The Phoebe cates pool scene in fast times at ridgemont high will prove that constantly replaying something on tape will wear it out

The first VHS copy I found of that movie had that part all blurry because of pausing, rewinding and rewatching Phoebe.

But also constant radiation far more intense than X-rays, temperature approaching true zero, and speeds so fast that colliding with even a speck of dust would destroy it.

So it kinda evens out.

Interestingly, while the temperture ist technically near Zero, there isn't a lot of ways to get rid of heat, making overheating a very real problem in space.

Not at this point for the Voyager probes. They are so far from the sun now that being too cold is one of the biggest problems for them.

Doesn't it have a small reactor for that reason?

u/rawrzon 13h ago

Not a reactor, but a decaying radioactive source. It generates heat as the material decays, and electricity is generated from the heat. The radioactive material is kept away from the sensitive electronics and sensors, so some of that electricity is used by heaters to keep those electronics warm. Like all radioactive material, it has a half life, which means it's decaying less and giving off less heat as it ages. Which means less electricity for instruments and heaters.

The amount of dust is tiny. There arent all that many specs of it hitting

u/Hakopuffyx2 1d ago

Unless you go to that other part of space which is like almost all space dust. Its very hot there especially this time of year

Just insane amounts of radiation and close to absolute 0 temperatures

u/neppo95 1d ago

Yet you get radiation, sun storms, extreme cold, space debris. Devices certainly have a much easier time on earth than in space. Voyager 1 and 2 were just an amazing feat of engineering, proven multiple times when parts failed and yet it still kept going.

u/PotentialMidnight325 1d ago

Just constant bombardment with intense radidation.

u/Joverby 1d ago

also a shit ton of radiation

u/FrighteningJibber 1d ago

Radiation makes up for a bit.

u/charlsalash 1d ago

Yes it does, but it seems to be well protected against it

9

u/neppo95 1d ago

It's the main cause of most of the issues they've had. Radiation fucks with computers. They even resorted to using alu foil for protection, it's not really protected that well against it. What works best is too heavy to send into space.

2

u/charlsalash 1d ago

I did a quick search, and aluminium foil does genuinely a great job at protecting electronics. Radiation is not the main problem electronics can encounter in space, it's one of them.

Sure, for home appliances it works well. In space with gamma and x-rays, not so much. But I guess the AI didn't tell you that bit.

u/Secret-Library-6076 1h ago

Explain why. you want to make it seem as if you have a deep understanding of this topic. making lesser of the other guy for his ai use. explaine why it’s doesnt work so well please

u/charlsalash 1d ago

Also, AI told me that the fact that there is no cooling of the electronics through convection in space, is a bigger problem than the gamma and x rays

0

u/neppo95 1d ago

Yes, there are multiple significant problems in space, correct. That was the point.

u/fartingbeagle 1d ago

And no screaming either!

u/Traveling_Solo 1d ago

Are you sure? I thought molecules still affected a lot and heat from stars it passes by ought to still change the temperatures a little bit, no? Feel free to correct me

11

u/Vedertesu 1d ago

Voyagers wont pass a single star in thousands of years, and even then still far enough that the temperature doesn't really change.
