Could it have crashed into something? I find it incredible that that hadn’t happened yet.

On the one hand, it has crashed into a lot of somethings—like cosmic radiation and micrometeorites. On the other hand, there is a lot of space in space, and the chances of Voyager crashing into something of the same or larger scale as itself is infinitesimal.

For a spacecraft launched half a century ago, it's unbelievable that it still works at all.

Whatever happened, it was temporary, because radio contact was established again after a 2-day pause.

I missed this, fantastic!

If it did crash into anything probably like a grain or sand or something stupid like that.
