Curiosity checks out its wheels

Having finished a two week look at a sea of sand, Curiosity’ science team has resumed its journey east towards the higher slopes of Mount Sharp.
Before they started out however, they decided to aim the rover’s high resolution mast camera at Curiosity’s wheels to see how they are faring and whether any of the damage that occurred in the early days of the mission has worsened. The photo on the right compares what was seen this week with the damage on the same wheel as seen in July 2020. This is also the same wheel I have posted images of since September 2017.
Not only does there appear to be no appreciable new damage to this wheel in the six months since July, remarkably, a comparison between today’s image and the photo from September 2017, shows little change as well.
In the more than three years since that 2017 photo, Curiosity has crossed Vera Rubin Ridge, crossed the clay unit, climbed up the next ridge to take a look at the incredibly rough terrain of the Greenheugh Pedimont, and then continued across the clay unit on its way to higher and possibly more challenging terrain.
In all those travels it appears this particular wheel has fared rather nicely, accumulating in at least this part little new damage. This bodes well for the rover’s future, as the wheels have been a concern since Curiosity’s first two years on Mars, when engineers found they were experiencing more damage than expected. The travel techniques they have adopted since to protect the wheels appear to be working.
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 print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
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

Looks like two new Morse characters are added to Curiosity’s wheels: a ‘T’ on number 5 and a ‘E’ on number 6 (looks like it will soon become an ‘I’.
For those of you who do not know, on the wheels are the Morse Code characters ‘JPL’ (· – – – · – – · · – · ·). They are not displayed on this photo.
Akin to AAA, we should invest in Rover Tire Repair.
Fly up, swap it out, return the embedded samples.
A can of Fix-A-Flat should do the job.
Hopefully the wheels have airow? gel in them to prevent the sand or rocks from entering the holes making the machine heavier, slowing the rover down
