Curiosity’s most damaged wheel appears to be surviving the rough terrain on Mount Sharp
For original images go here and here.
In today’s download of images from Curiosity was a set of pictures taken by its Mars Hand Lens Imager (MAHLI) of the rover’s wheels, as part of the science team’s routine inspection procedures after every 500 meters of travel.
The picture to the right shows what I think is the rover’s left middle wheel, its most heavily damaged, comparing what that wheel looks like now versus what it looked like in November 2022. At that time five of the wheel’s zig-zag grouser treads were broken, three of which are visible in both pictures. The numbers indicate identical wheel treads.
As you can see, after more than seven months of travel across some of the roughest and rockiest ground so far seen on Mars, no more grousers have broken in the new picture. The plus (“+”) signs indicate places where I think some additional metal between the grousers appears to have broken away, but even here the additional damage appears minimal.
Based on past wheel inspections, I expect more images will be taken in the next day or so. We shall see if those pictures indicate any further damage elsewhere. Based on this new picture, however, it appears that the care the science team takes in picking Curiosity’s route, as well as its software (designed to avoid the worst terrain), is continuing to preserve the wheels from further significant damage.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I am all for the preservation of tracks.
What suggestions for next generation track design and materials is the enginnering crew reviewing ?
Carry on Curiosity !!
