NASA’s Voyager 2 has lost communication with Earth due to an unintentional shift in its antenna direction. The next programmed orientation adjustment on October 15 is expected to restore communication, while Voyager 1 continues to operate as usual.

A series of scheduled commands directed at NASA’s Voyager 2 spacecraft on July 21 led to an unintentional change in antenna direction. Consequently, the antenna moved 2 degrees off course from Earth, causing the spacecraft to lose its ability to receive commands or transmit data back to our planet.

Oh absolutely not. I'm just wondering if we could get stupidly lucky XD maybe it happens to be pointing at Voyager 1 (honestly idk how the trigonometry works out but maybe New Horizons?? Lol)

A shift of 2° at 12.3 billion miles means it’s now pointing about 430 million miles away from the earth. The likelihood that it would be pointing at one of the small handful of man made objects that are out that far is infinitesimally small. Imagine being in a filed 100 miles wide and spinning a bottle with a laser pointer on it and hoping it lands pointing at a single bottle cap at the edge of the field. That would be magnitudes more likely than this pointing at one of our objects. And even if it did, those also would have antennas pointed at Earth so they couldn’t receive the message without turning which might cause the same issue for them.

I’d guess even if some other man made satellite is perfectly in line, those wouldn’t have even close to the necessary transmission power to reach voyager.

We're talking about the most proverbially gone shit in human history. Not only is it too far away, it is going faster than any man-made object has ever gone.

...And we once launched a massive metal disc out of a giant bore hole with a nuclear explosion.

Edit: actually Operation Plumbbob sent the steel bore cap nearly 4x as fast as Voyager. Suck it, nerds.

The fastest man-made object would be the NASA Parker Solar Probe spacecraft which reached a speed of 535,000 kilometers per hour...0.05% of the speed of light

Holy shit, that's significantly faster than a steel plate that was launched by a nuke and subsequently vaporized. Insane. Thank you
