The aging power-challenged Voyager 1 spacecraft suffered another glitch 2 weeks ago – it stopped calling home on its regular channel. Here is the sequence of events that transpired -

Oct 16 – Command sent to turn on a heater
Oct 18 – X-band signal lost; team surmised that the power-overload triggered the fault protection system and Voyager switched to a low-rate low-power X-band mode
Oct 18 – DSN looked for lower-rate X-band signal and found it

    Three weeks after Voyager 1 autonomously flipped over to using the S-band transmitter for communicating with earth because of a power overload condition, it appears that it is back to communicating using X-band.

    No word from NASA, but presumably the team managed to turn off the heater that caused the power surge and re-enable the X-band transmitter.

    Phew 😓
