The obvious visual evidence for assuming Mars once had catastrophic floods
Click for original image.
Since the first comprehensive orbital data of Mars was sent back in the early 1970s by Mariner 9, scientists have generally concluded that many of the features seen at the eastern end of the giant Valles Marineris canyon were caused by one or several catastrophic floods.
The picture to the right, rotated, cropped, and reduced to post here and taken on July 26, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), provides a good example of why the scientists have come to that conclusion. It shows what the camera team labels a “streamline feature surrounding crater.” I have added the arrows to indicate the presumed direction of flow. The flow went around this 2.5-mile-wide unnamed crater because the impact had compacted it, making it resistent to erosion. The flow however was strong and large enough to wash away the plateau on which the crater sits, as well as cutting into the crater’s southwest rim. In addition, the rim on the southeast was also cut through at some point, this time from what might have been flow eddies as the flood pushed past.
Hence, the theory of catastrophic floods.
The white dot on the overview map to the right marks the location, about 60 miles southeast of where Mars Pathfinder and its Sojourner rover landed in 1997. The inset gives a wider view, which shows more clearly the entire streamlined geology around this crater. In this case, the flood that washed around this crater came out of the long Ares Vallis channel, whose source is not Valles Marineris but the cratered highlands to its east.
As must be stated every time this hypothesis of Martian catastrophic floods comes up, the theory has problems. Though all the features both in close-up and in all the surrounding terrain looks like a sudden flash flood of gigantic proportions had come through — including data that suggests the past existence of intermittent oceans and seas following those floods — the fundamental problem is that planetary scientists have yet to come up with an acceptable model what would make liquid water possible on the surface of Mars, now or anytime in the past. The visual and orbital evidence insists on giant flash floods, but the long term geological and atmospheric evidence says no. The planet was always to cold with too thin an atmosphere. There are models that posit the atmosphere was once thicker and warmer, but no one is convinced by any of them.
Nonetheless, this picture illustrates why catastrophic floods are believed to occur on Mars. It will likely take scientists on the surface, with rock hammer in hand, to solve this mystery.
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.
