The big cliffs of Gediz Vallis on Mars
Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 21, 2021 by Curiosity’s chemistry camera (ChemCam), normally designed to look at high resolution close-up imagery of nearby objects.
However, it can also be used as what the science team call “a long distance spyglass.” The image to the right is an example, looking at what I think are the distant but steadily approaching big cliffs on the western wall of the canyon Gediz Vallis. Make sure you look close at the shadowed cliff-face, probably several hundred feet high. It is filled with huge rock faces reminiscent of the most stark rock cliffs on the mountains of Earth.
The two images below provide the context, which makes the image even more quite breath-taking.
The first photo to the right, cropped and reduced to post here, was taken by Curiosity’s right navigation camera of these mountains. I think the close-up above is of one of the two nooks indicated by the white arrows. The canyon cutting into the mountain is dubbed Gediz Vallis. Curiosity will eventually be inside this canyon, though to get there the present plan is to circle around the backside of the mountains on the right.
The map shows Curiosity’s position as of about a week ago, with the white lines indicating the approximate view seen in the navigation camera’s image.
As Scott Guzewich, Atmospheric Scientist at NASA’s Goddard Space Flight Center, noted in today’s update on the rover’s blog,
We’re always looking ahead to our future activities and this plan is no exception as we’ll continue using ChemCam as a long distance spyglass for imaging the sulfate-rich geological unit (a portion of which is seen in this image) uphill from our current location.
Because the rover will not actually drive straight into Gediz Vallis, according to its presently planned route, it will never be directly below the cliff seen above. Thus, they are beginning to get good images of it now, and will continue to do so until the rover swings around the north end of this ridge to come into the valley from the west and to the south of this cliff. At that point they might be able to view it again, but it will be from a sharp angle that will make it hard to see all details.

Please consider supporting my work here at Behind the Black. Your support allows 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. 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. Only now does it appear that Washington might finally 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.

For those familiar with Mount Everest, the top picture reminds me of the famous “Second Step” on the North face. Maybe the Chinese will put a ladder up there.
It took me a moment to realize that I wasn’t looking at Mars from orbit, but from ground level. A Very Cool Image.
