Readers!

 

My July fund-raising campaign to celebrate the fifteenth anniversary since I began Behind the Black is now over. I want to thank all those who so generously donated or subscribed, especially those who have become regular supporters. I can't do this without your help. I also find it increasingly hard to express how much your support means to me. God bless you all!

 

The donations during this year's campaign were sadly less than previous years, but for this I blame myself. I am tired of begging for money, and so I put up the campaign announcement at the start of the month but had no desire to update it weekly to encourage more donations, as I have done in past years. This lack of begging likely contributed to the drop in donations.

 

No matter. I am here, and here I intend to stay. If you like what I do and have not yet donated or subscribed, 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

Curiosity climbs onto the Marker Band

Panorama as of January 17, 2023

Overview map

Curiosity’s exploration of the foothills of Mount Sharp continues. The panorama above, cropped, reduced, and annotated to post here, was taken on January 17, 2023 by the rover’s right navigation camera. It looks forward across the flat marker band terrain that the rover has been studying for the past few weeks.

From orbit, this marker band appears very smooth and flat, and is found in many places on the flanks of Mount Sharp, always at about the same elevation. The arrows in the overview map to the right mark several places near Curiosity where the band is evident. The blue dot marks Curiosity’s present location, the red dotted line its planned route, and the yellow lines indicate the approximate area covered by the panorama above. The distance across the marker band to the uphill slope is about 500 feet.

Now that Curiosity is on the marker band, it no longer looks smooth. Instead, it is a flat plain of many uneven paving stones interspersed with dust. While not as rough as the Greenheugh Pediment, which Curiosity had to retreat from because it was too hard on the rover’s wheels, the marker band is hardly the smooth soft terrain implied by the orbital images.

These paving stones have also proven difficult to drill into, with Curiosity’s drill already failing twice previously because the rock was too hard. That hardness should not be a surprise, however, as this layer’s flatness in many places shows its resistance to erosion.

As it crosses this wide section of the marker band the science team will obviously be looking for more candidate drill sites. Sooner or later one should work.

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
