Engineers rethinking Ingenuity operations to keep it alive through the winter
The engineering team operating the Ingenuity helicopter on Mars have now determined that the cold oncoming winter temperatures on Mars are causing its systems to shut down during the night — at the edge of their designed temperature limits — and then reboot each morning, thus resetting its clock to the wrong time.
The result has been that the helicopter’s future is now definitely threatened. To address the cold winter temperatures and possibly keep Ingenuity alive, the engineers have come up with the following plan. First, they have focused on downloading from the helicopter all the remaining data still on-board, in case it shuts down permanently.
After all critical logs are transferred, the team will proceed with a recommissioning phase during which we will reestablish Ingenuity’s flight-readiness given our ongoing overnight cold-cycling. Like during the technology demonstration phase, we will perform a high-speed spin before proceeding to flight. Should Ingenuity receive a clean bill of health, we would be ready to execute a short sortie to the southwest in Flight 29. This flight will improve our radio link for approximately the next four to six months while Perseverance samples at the river delta.
In the meantime, the Ingenuity flight software team will be preparing a series of upgrades to enable advanced navigation features. These new capabilities will help Ingenuity ascend the river delta and continue its missions as a forward scout for Perseverance past winter.
All this effort will carry much greater risk, especially because Ingenuity is now operating far beyond its original planned capabilities, and the worst and coldest winter temperatures are yet to come. For the next three months or so the amount of sunlight available will be insufficient to power it as planned, and thus it will face a possibility of permanent failure almost every day. That 29th flight is thus likely critical to survival.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
