Cool image time! The photo to the right, taken on June 18, 2022 by high resolution camera on the Mars rover Curiosity, provides a close-up of the area indicated by the arrow in the navigation camera image above taken three days earlier.
Because the rover had moved uphill slightly during those three days, the close-up can peek over what was the most distant ridge to see farther up Mount Sharp. (For context take a look at the overview map here.) All told, this close-up to the right shows four mountain ridges/ranges. First we have the ridgeline to the right, partly in shadow, which forms the right wall of the saddle that Curiosity appears heading for. Next we can see to the left the top section of the large 1,500 foot high mesa on the other side of the canyon Gediz Vallis. Note its many layers, all of which are going to become a major item of study as Curiosity gets closer.
Third we have a very rough and tumbled ridgeline, formed in a layer the geologists have dubbed the sulfate bearing unit. This layer tends to be very light in color, and more easily eroded. Curiosity is presently beginning to move into this layer as it climbs.
Finally there is the most distant ridge, which is simply the higher reaches of Mount Sharp though not its peak by a long shot.
The dusty winter air is quite evident by the chariscuro effect, causing the more distant ridges to appear more faded.
Note: This will be the first of three cool Martian images today. Stay tuned.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to
