Hallelujah! And Congrats all around.

JPL just announced that engineering data was successfully received from the Voyager 1 spacecraft on Saturday April 20, the first time since Nov 2023.

The commands sent on Thu to relocate some code around the failed memory chip in the FDS worked as expected.

Science data is not being received yet; it will require relocation of some more code in the sparse free memory areas in the FDS.

DSN in Canberra should be receiving a full memory read-out of the Voyager 1 FDS computer as we speak. This will help with the planning for further code relocations to enable transmission of science data soon.

Six months after it suffered a serious brain injury and after months of mind-boggling ultra-long-distance surgery, the Voyager 1 spacecraft walked and talked at full data rate today!

After transmitting a full memory readout on Friday at 40 bps, Voyager 1 switched to the science-mode 160 bps rate, which presumably the DSN site at Goldstone was able to receive and decode today.

Congrats and kudos to all who made it happen.
