Voyager's 15 Billion Mile Software Update (youtube.com)

Have you ever wondered how NASA updates Voyager's software from 15 billion miles away? Or how Voyager's memories are stored? In this video, we dive deeper into the incredible story of how a small team of engineers managed to keep Voyager alive, as well as how NASA could perform a software update on a computer that's been cruising through space for almost half a century.

I completely agree. And the video didn't discuss how any of that actually happens, except to say that they send the update over radio, and to give a brief description of how the storage system on Voyager works (physically, not logically). That's what I meant by "really nothing here", "here" meaning "in the video", not "in how the Voyager probe works and updates are carried out".

That next line, "It turns out they they update the software by sending the update by radio," was meant to be a bit sarcastic, but I know that isn't obvious in text, so I've added a signifier.
