InSight resumes limited science operations
InSight on February 5th resumed science operations, reactivating its seismometer to record Martian quakes.
As I suspected in my previous InSight update, the lander’s life is still coming to an end.
The mission, though, has been grappling with a gradual decline in the spacecraft’s power because of dust accumulating on its solar arrays. Unlike the Spirit and Opportunity rovers, whose arrays were regularly cleaned by atmospheric activity, dust has continued to accumulate on InSight’s arrays. At a meeting of MEPAG in June 2021, Banerdt projected that power levels would drop below that needed to keep the spacecraft alive in the spring of 2022.
That date has been pushed out slightly, but he said the long-term outlook for the lander still does not look promising. “Our current projections indicate that the energy will drop below that required to operate the payload in the May/June time frame and probably below survivability some time near the end of the year,” he said.
They might still squeeze a month or two more from the lander, but unless they are very lucky and a dust devil blows across it, the end is coming.

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.
