Curiosity’s wheels: Maybe not so bad after all
To see the original images, go here and here.
Today the science team for the Mars rover Curiosity downloaded more photos of its wheels, a survey taken routinely now after every 500 meters or 1640 feet of travel. Unlike the pictures made available yesterday that showed some of the worst damage to one of Curiosity’s middle wheels, these new images included the wheel I have been tracking since 2017 as a baseline to see if further damage has occurred.
The photos to the right show that wheel, with the top photo from August and the bottom created from two pictures taken on November 20, 2022. The numbers indicate the matching treads. The “+” sign in the top image indicates a location where new damage was spotted in August.
As you can see, this wheel does not appear to have experienced any additional damage in the more than three months since that August update. While the damage to Curiosity’s wheels remains very concerning, it does appear based on this one wheel that — despite the generally very rough terrain the rover has been traversing since it entered the foothills of Mount Sharp — the wheels in general seem to be holding up.
Though I have not done a careful comparison of these new wheel images with earlier ones, none of the new images appear to show any additional significant damage. It appears that the travel criteria the science team adopted years ago — right after discovering the wheel damage — continues to work to protect the wheels. It picks the rover’s path more carefully to avoid sharper rocks, and includes software that stops the rover should it sense it is crossing a rock sharper than desired.
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.

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.

Maybe it’s the lighting, but the damage to Tread 5 looks a bit more severe to me in the second picture.
Andi: I think it is the lighting. Having looked at a lot of this images, I have found often that the light can make sections seem missing when they are simply not lit, and they reappear in a later photo.
