Voyager 1 Fault Forces Transfer To S-Band

We hate to confess it, however every time we see an editorial about both Voyager spacecraft, our ideas instantly flip to worst-case eventualities. One among at the moment, we’ll be compelled to put in writing obituaries for the plucky interstellar vacationers, however these days isn’t that day, even with information of but some other factor aboard Voyager 1 that threatens its talent to keep in touch with Earth.
In line with NASA, the present drawback started on October 16 when controllers despatched a command to activate one of the vital spacecraft’s warmers. Voyager 1, just about a light-day far away from Earth, failed to reply as anticipated 46 hours later. After some looking, controllers picked up the spacecraft’s X-band downlink sign however at a far decrease energy than anticipated. This indicated that the spacecraft had long gone into fault coverage mode, most probably in accordance with the command to show at the heater. An afternoon later, Voyager 1 stopped speaking altogether, suggesting that additional fault coverage journeys disabled the tough X-band transmitter and switched to the lower-powered S-band downlink.
This was once probably mission-ending; the S-band downlink had ultimate been utilized in 1981 when the probe was once nonetheless smartly inside the confines of the sun machine, and the concern was once that the Deep Area Community would now not be capable of in finding the vulnerable sign. However in finding it they did, and on October 22 they despatched a command to substantiate S-band communications. At this level, controllers can nonetheless obtain engineering knowledge and command the craft, but it surely continues to be noticed what may also be accomplished to revive complete communications. They haven’t attempted to show the X-band transmitter again on but, properly who prefer to additional review what led to the fault coverage error that kicked this entire factor off prior to committing to a step like that.
Following Voyager information at the moment feels a little bit morbid, like a loss of life watch on an ageing superstar. Right here’s hoping that this tale seems to have a contented finishing and that we will be able to push the inevitable off for some other few years. Whilst we wait, if you wish to know a little bit extra in regards to the Voyager comms machine, we’ve were given a deep dive that are supposed to get you going.
