InSight power levels continue to hold steady
According to a new update posted today by the InSight science team, the power being generated by the lander’s dust-covered solar panels once again did not decline last week, holding at 400 watt-hours generated per day for the fifth week in a row.
The graph to the right shows the trends since May. The dust in the atmosphere is indicated by the red line, marking what scientists call the tau level. A normal level outside of the winter dust season should be between 0.6 and 0.7 tau. Even though that dust season has been ending, that level has remained high, thus cutting off more of the sunlight that the Mars lander could use to generate the electricity needed by its seismometer.
That the power generated continues to hold steady however suggests that InSight’s seismometer might be able to continue working into September, detecting Martian earthquakes. The scientists had predicted the spacecraft would die sometime around now. Without doubt they are thrilled their prediction appears wrong.
That the lander might last longer also increases the chance that it might experience a wind event, such as a dust devil, that could blow the solar panels clear of dust and save the lander entirely. All it needs is one such event, which sadly has not occurred since InSight landed on Mars in 2018.
Readers!
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.
