Both voyagers recorded temperatures ranging from 54,000 to 90,000 degrees.
How doesn’t voyager melt?
No way anything man built can withstand those temperatures, they mean that voyager register space dust or gasses at those temperatures but didn’t cross it? Or something else?
The vacuum of space is cold. But the one molecule per square meter of space dust can be extremely hot. You can drop a match in a swimming pool and the water won’t change temperature at all.
Their analogy is just a touch backwards depending on how you’re visualizing it. It DOES touch the heat. It traveled through a huge region that was that hot. The match is an extremely hot particle and the pool is Voyager. Their point is a single molecule, even at 30,000 degrees, isn’t going to transfer much actual energy to the space craft.
The measured temperature is more of a function of directly detecting some lower temperature and cross-referencing density measurements. It’s not enough molecules to heat up the spacecraft to the same temperature, so figuring it out becomes a function of how much heat is being absorbed and radiated back out in relation to the detected density of particles. So per detected particle, it’s getting a lot of heat, but there aren’t enough particles to really heat the whole craft up much at all.
Despite what capitalists would like you to believe technology hasn’t changed all that much in 50 years. Sure there have been some novel technologies more recently like blue LEDs or CRISPR-Cas9. But the real advance since the 70s has been in miniaturization, allowing more things to be put in the same amount of space as before.
Also one point of clarification, Voyager is a space probe, not a satellite. Satellites orbit things and can be naturally occurring.
Technically even the Voyager probes are orbiting something. It isn’t a planet, and not even the sun anymore. It is orbiting Sagittarius A*, the black hole at the center of the Milky Way.

This explains the situation better but fails to explain how it detects these temperatures without touching them.
I assume its infrared cameras and the like. But this also implies the “wall of fire” is actually full of holes or its bound to collide with that heat.

But how does a satellite built 50 years ago even detect the energy of that single particle in the vacuum of space? That’s mind boggling.

But yeah, probe is the more accurate term.
I had a feeling somebody was going to point that out…
The entire concept of temperature breaks down when there isn’t much material around. Nobody should be talking about the temperature of empty space.
That means you, satcom engineers!
Basically like the sparks from a grinder. The individual sparks are glowing hot but they’re too small and too few to do any harm.
