Cracks and scallops on the lowland plains of Mars
Click for full image.
Cool image time! To the right is some of the strange terrain seen in the northern lowland plains of Mars. The photo, cropped to post here, was taken on May 4, 2020 by the high resolution camera of Mars Reconnaissance Orbiter (MRO) of an area in the northwest part of Utopia Planitia.
Next year China’s first attempt to soft land a rover on Mars will occur somewhere in Utopia Planitia. Utopia Planitia, also called Utopia Basin, is quite large, however, and in fact is the largest recognizable impact basin on Mars, with a diameter of more than 2,000 miles or about two thirds the width of the United States. If this strange spot was put near Seattle, Tianwen-1 is expected to touch down somewhere near Houston, Texas.
The MRO science team labeled the image “Scalloped terrain in Utopia Planitia.” The curved cliffs in the image illustrate those scallops, found frequently in Utopia. Their formation is believed related to the sublimation of underground ice, changing directly from ice to gas. The theories of this process however are somewhat uncertain at this time.
What stuck me about the image were the north-south oriented cracks. They extend through the full image, all oriented in the same direction. I haven’t the faintest idea what caused them, but they are intriguing, are they not?
This terrain is also different than most Utopia Planitia images I have previously posted. Most look squishy and blobby and distorted, suggesting the presence of soft slush and underground ice. This image instead suggests hard bedrock, even though it is farther north than the previous images and should thus be expected to have more ice underground. Quite mysterious.
I suspect the ice is here, but is simply not made obvious by any surface event. Then again, who knows? The geology of Mars is definitely not obvious, no matter how obvious it sometimes seems.
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.

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.
