InSight fails to respond during scheduled communications session
Since December 15, 2022 engineers have been unable to contact the Mars InSight lander, which likely means its power levels have finally fallen so low that the spacecraft is no longer functioning.
On Dec. 18, 2022, NASA’s InSight did not respond to communications from Earth. The lander’s power has been declining for months, as expected, and it’s assumed InSight may have reached its end of operations. It’s unknown what prompted the change in its energy; the last time the mission contacted the spacecraft was on Dec. 15, 2022.
The graph to the right shows the decline in InSight’s power levels since May. The atmosphere has been clearing following the dust storm in October, indicated by the drop in the tau level. Normal tau levels outside of dust storm season are around 0.6-0.7. It is therefore likely that as this dust cleared, it also settled on InSight’s solar panels, and reduced their ability to generate power to the point the spacecraft ceased functioning.
This is very much the same thing that put the rover Opportunity out of business in 2019.
According to this update, engineers are going to continue to try to contact the lander, but it is likely that this effort will end in about a week, should no contact be successful.
The support of my readers through the years has given 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. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
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. Even today NASA and Congress refuse to 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.

Since this seems to be such a frequently reoccurring problem, maybe they need to devise a simple windshield wiper system for their solar panels…
Ryan Lawson,
NASA may not consider it the problem that you do. These missions have limited expected lifespans, but they do seem to routinely exceed these mission timelines. Generally, the landers and rovers are not built to last much longer and the extra time is considered a bonus. To put a solar cell cleaner on the craft would cost weight that the scientists want to use for instruments and experiments. When budgeting the mission, they don’t really budget for longer missions and must request mission extensions in order to receive additional budget for additional data collection (ground controllers and Deep Space Network time to collect the data, and scientist salaries to write the additional papers explaining the data). For these reasons, it is not really considered cost effective to put solar cell cleaners on these craft at the design phase of the mission. Longer missions, such as Curiosity or Perseverance, tend to be designed with other power sources so that reliability and longevity are assured.
Perhaps one of these years someone will design a solar array cleaner that is lightweight and effective so that these longer missions can use solar arrays rather than the other power sources. It does seem to be a shame that we are losing our only seismometer on Mars.
