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

    @[email protected] The Voyager mission was and is amazing! I just looked at DSN Now. Canberra is receiving Voyager 2 signal. The power received is -160 dBm (1.0 x 10^-22 kW)! Goldstone is on Voyager 1 but there’s no transmission either up or down. It says round trip light time to Voyager 1 is 1.91 days and to Voyager 2 it’s 1.60 days.
