1. Voyager 2 has been pointing 2 degrees off from Earth
2. Been that way for a while and nobody noticed because very old computers.
3. Meaning that the probe has gone dark (ingress and egress comms are not possible)
4. However, both Voyager probes have software that tells them to routinely calibrate themselves every few months
5. Meaning that it should point at Earth in the next few months (most likely).
