Perseverance moves west, into the barren hinterlands beyond Jezero Crater

Cool image time! The panorama above was created using two pictures taken on December 4, 2025 (here and here) by the navigation camera on the Mars rover Perseverance. The view I think is looking west, away from the rim of Jezero Crater, which now lies behind the rover to the east.
The blue dot on the overview map to the right marks Perseverance’s position when it took this picture. The yellow lines indicate my rough guess as to the area covered by the panorama. The white dotted line marks the actual route the rover has taken, while the red dotted line the original planned route.
As I noted in my previous Perseverance update in mid-November, the science team has apparently decided to revise the route, abandoning initial plan of going back uphill towards the rim and instead travel downhill into the hills beyond. This is a region that orbital data has suggested might be rich in minerals, making it a prime mining location for future colonists. My guess is that the science team decided they needed to get there, that they had enough data from the rim and that it was now more important to get to the western mineralogy.
Though I am sure they are using the highest resolution orbital images from Mars Reconnaissance Orbiter (MRO) to guide them, the Perseverance team has not yet upgraded its interactive location map to show those details in this western region. Thus, the map in this area is fuzzy and not as detailed.
The team has also not published its revised planned route, so there is no way to guess where the rover will go next. It does appear however that it is finally leaving Jezero Crater for good.
And as all recent pictures from Perseverance, these images show this Martian landscape to be utterly barren, its hills and valleys softened by dust and eons of erosion from the very thin Martian wind. This is an alien place, though it has the potential with human ingenuity to bloom if we have the courage to try.
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 or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Perseverance has now completed four campaigns, and is now on its fifth; it is, so to speak, now in “bonus time.” I think they feel a little freer to expand the palate of science objectives now that the basic science mission of Perseverance is now complete.
Here’s hoping that Percy has many campaigns in its future, before its RTG runs down.
P.S. That’s another amazing photo.
Looks like fairly smooth terrain (Marsrrain?). Time to floor it?
