Another “what the heck?” image from Mars
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 14, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists simply label as “exposed crater floor materials.”
I label it as another one of my “what the heck?” images, showing features that in some ways defy understanding or explanation. The picture shows a small area of the floor of an unnamed 14-mile-wide crater, with its rim indicated. Though clearly visible in orbital photos, the crater is nonetheless heavily eroded and even appears partly buried, possibly by flood lava.
The complex floor features however are not anything usually seen in flood lava terrains. The terrain colored blue in the color strip likely indicates coarse material like sand or rocks or rough bedrock, while the reddish terrain suggests the surface is heavily coated with dust.
The white dot on the overview map to the right marks the location, in the dry tropics of Mars and about 600 miles east of the region explored by the rover Opportunity.
The inset shows that the prevailing winds in this region blow from the east to the west. Inside the crater winds have apparently ripped off the top layers, exposing this strange terrain underneath and blowing dark material to the west.
The colors in the picture above strengthen this conclusion, as the dark blue material appears like rough eroded rock while the surrounding terrain is covered by ordinary red Martian dust. That dark rock and sand is possibly very old lava material that is now exposed and being broken apart and blown away by the winds.
Why however is that exposed material so twisted with bright and dark sections? I haven’t the faintest idea.
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 the past two weeks has the 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 refuses 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.

Perhaps Richard Hoagland and his team can help you figure it out.
Maybe you should do a top ten WTH Mars geology mystery pics post sometime.? You cover these periodically, would be interesting to see a back to back of the best ones from these many years.
Ryan Lawson: First: I have edited your comment slightly, since your acronym for my “What the heck” images instead implied I used an obscenity instead. Why would you do that?
Second, you make an excellent suggestion. I’ll think about it. Right now I am trying to get back up to speed after my break the past few days.
