A Martian hill of pillows
Click for original image.
The cool image above was taken on January 31, 2023 by the left navigation camera on the Mars rover Curiosity. The red dotted line indicates roughly the planned route forward for the rover, though as Curiosity gets closer to that hill the terrain is looking increasingly difficult. The white box in the panorama below, taken two weeks earlier when the rover was about five hundred feet away, indicates the area covered by this picture. Since then Curiosity has traveled about 200 feet closer.
I post this picture specifically because of the small hill to the right of that path. Probably no more than fifty feet high, its entire surface appears cloaked by a pile of large, pillow-like pavement stones, almost as if the ground below had been washed away so that the massive top layer fell downward over time. Later, wind erosion over eons smoothed the rough edges of those massive blocks, giving them their cushion-like shapes.
This is strange geology. You might see such strange geology on Earth, but rarely. On Mars however strange geology appears increasingly common.
Moreover, to get a 3D sense of this terrain, load into your browser (on separate tabs) the full images of this hill, taken by Curiosity’s right and left navigation cameras (here and here). If you switch back and forth quickly between those tabs, you will see the slight shift in position between the two cameras, and be able to perceive this hill in three dimensions.
Readers!
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.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Any signs of Marvin K-9 and those Instant Martians yet?
Pillow lavas are fairly common on earth, but form when basaltic lava is extruded under water (as on the flanks of a Hawaiian island, or along a mid-ocean ridge). Hmm…
