Readers!

 

The time has come for my annual short Thanksgiving/Christmas fund drive for Behind The Black. I must do this every year in order to make sure I have earned enough money to pay my bills.

 

For this two-week campaign, I am offering a special deal to encourage donations. Donations of $200 will get a free autographed copy of the new paperback edition of Genesis: The Story of Apollo 8, while donations of $250 will get a free autographed copy of the new hardback edition. If you desire a copy, make sure you provide me your address with your donation.

 

As I noted in July, 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. 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.

 

Please consider supporting my work here at Behind the Black. 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

A cracking and collapsing glacier on Mars

Fractured ice sink hole on Mars?
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on November 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a small portion of the floor of a very ancient and eroded unnamed 40-mile-wide crater on Mars.

MRO’s science team labeled this picture simply as a “Fractured Feature.” The section I have focused on in the cropped image is clearly the fractures the scientists were interested in. What is heck caused this?

The location is at 39 degrees north latitude and is located at the very western end and in the center of the 2,000-mile-long mid-latitude strip I call glacier country because practically every photo exhibits evidence of glaciers. Thus, this fractured terrain is almost certainly evidence of ice that partly buried and thus protected from sublimating away.

The collapse feature indicates more, however. The circular shape of the fractures suggests that the center of this feature is sinking, with the ice on all sides slipping downward and breaking as it does so. The location however is not in the center of this crater, but near its southern interior rim. Moreover, in a wider image from MRO’s context camera this feature appears to be within what looks like a thick patch of ice filling most of the southeast quadrant of the crater. On it are other similar collapse features.

The data suggests that this ice patch is eroding, but doing so influenced by the rough terrain on which it sits. The sinks suggest the glacial ice is sublimating first over low spots, but this is hardly certain.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
