    Thanks for the pointer...well worth a watch.

    The above told me that the Voyager digital data tape recorder is driven by a rubber belt and uses 328 m of 1/2 inch 8 track tape, capable of holding 67 Mb data at launch. The total power available to the craft was 470 W at launch and that too degrades over time.

    It's 67MB, or 536Mb.

    And it's been that way since 2002. That's something I had not realised, thank you.

    Whichever way one cuts it, it's a magnificent piece of engineering bearing in mind that an average PC is pretty much unusable garbage after a hand full of years.

    The fact that NASA can communicate with it over millions and millions of miles is amazing frankly, bearing in mind my mesh system doesn't even reach the en-suite.

    I agree.

    That digital communications over such a distance is a) possible b) still effective in controlling Voyager is a marvel (IMO).

    That the onboard computer can still be reprogrammed by those communications is somewhat astonishing. That there are digital to analogue converters onboard that can translate the messages to electromechanical devices to steer antennae etc stands as a monument to the depth of forethought and planning applied by the designers and constructors.

    It does have a hint of Space Cowboys in it

    Given the memory available to be used, I’m amazed how future proof they appear to have made it. To be updated remotely just blows my tiny mind!

    These days, 67MB doesn't even cover one full resolution image taken on an iPhone 15 Pro Max; and that's for entirety of a space craft including data recording - on a piece of tape.
