Vger will come back, eventually.
Ah, so this must be when it encountered the early borg that created Vger. EDIT: Maybe Aliens picked it up last night and they are on their way here now because we forgot to include a golden record player.
I would love to read about specifically what went wrong in 1981.
The closest I could find was this old article from 1981: https://www.nytimes.com/1981/08/28/us/swivel-on-voyager-stil...
But there isn't nearly enough detail in it. Is there an analysis anywhere online of that event?
NASA tech often seems to outlive its initial mission length by a massive margin. The Mars rovers spring to mind. It's incredibly impressive, and almost embarrassing! Surely this isn't accidental. Is the kit massively over-specced? Do the uncertainties and risks necessitate such a depth of redundancy that when stuff goes kinda smoothly the thing lasts 9 times longer than it was designed to? Is it a political thing: they set their success criteria low just in case something goes wrong, but actually intend a much longer lifespan?
Sorry if this seems an incredibly cynical way of looking at the world. I actually love all this stuff - I'm just curious if there is a pattern here and what the reason is if so.

We receive information that its radios are still working.
Communication is exchange of information . The sun is not communicating with us, and we know its "radio" is still working. It's a pedantic, and incorrect, argument against the headline. The guidelines actually say not to do this, even when you're right.

One-way communication is a valid type of "communication".

Signal processing algorithms can pull out a signal from well below the noise floor these days. Even the small and nondirectional antennas on your phone are good enough to receive GPS signals even all the way down at -125 dBm, which is WAY less than your phone receives in interference from random radio stations and faulty LED bulbs nearby. The tech used to receive Voyager signals is not really different, just more sen…
Interesting! Why faulty LED bulbs in particular, does it have to do with their PWM frequency?

I find it interesting how they use “aging spacecraft” and “exceptionally long lifespans” of these devices. In terms of the age of the universe, or the time that light from a star has travelled to us, it’s minute. Aging in relation to human life maybe.
