Cliffs inside 285-mile-wide Schiaparelli Crater on Mars
Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and was labeled by the science team as showing “dramatic cliffs and swirls in mound-skirting unit.”
I estimate the tallest point of this cliff butte to be somewhere between 500 and 800 feet high. And while the cliff is what first attracts the eye, one mustn’t ignore the vast amounts of dust and sand that cover everything here. The small teardrop-shaped buttes on the upper plateau suggest the prevailing wind direction there is from the north to the south. However, the north-south orientation of the ripple dunes on the floor below suggests that the prevailing wind direction below the cliff is east-west. Explaining how the topography could so quickly change the prevailing wind direction is beyond my skill.
The swirls mentioned by the scientists can be seen at the top of the cliff (on the left) and just below its base, in areas where there appears to be less dust. Those swirls reveal the many geological layers here.
The black dot on the equator about 550 miles east of Opportunity on the overview map to the right marks the location of this cliff, on the northwest interior rim of 285-mile-wide Schiaparelli Crater, one of the larger craters on Mars and also one of the oldest, its rim and interior much changed with many layers formed by Mars’s endless climatic and geological cycles, some caused by volcanic events and others by the repeated swings of the planet’s rotational tilt. The swirling layers in this picture illustrate those past events.
This location, on the equator, is dead center within the dry equatorial regions of Mars. Thus, at this moment in Mars’ geological history it is wind and sand that is changing its face.
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.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. 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.

I wish there was a 3D version of this picture – to see some “depth”
