And then 45 hours of waiting to see what happens. Well, not quite, on Friday another pair of commands get sent, `CCSA FULMRO` and `CCSB FULMRO`. Those seem unrelated, and given that the response that comes back is quite large (takes over 1h to receive), I think that's a request for each CCS (remember they're paired) to send back a memory dump ("full memory read-out"). I don't think that's related to the patching, but maybe the CCS memory has some state about how the patching went?

On Saturday, jubilation! The schedule shows that Voyager 1 acknowledged the 5 patch commands, and the DSN started getting engineering telemetry again. It worked! They fucking re-linked a program on a 46 year old computer in deep space, and it worked! I'm not sure I could do that to a program on my local computer, with all the tools and instant feedback! It's bananas!

@danderson@hachyderm.io You have to be able to dump the memory to verify that the relocation worked.
