Please consider supporting my work here at Behind the Black. I keep the website clean from pop-ups and annoying demands. Instead, I depend entirely on my readers to support me. Though this means I am sacrificing some income, it also means that I remain entirely independent from outside pressure. By depending solely on donations and subscriptions from my readers, no one can threaten me with censorship. You don't like what I write, you can simply go elsewhere.

 

You can support me either by giving a one-time contribution or a regular subscription. There are five 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:

4. A Paypal subscription:


5. Donate by check, payable to Robert Zimmerman and mailed to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage or shown in the menu above. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.


Perseverance catches up with Ingenuity

The photo above, cropped, enhanced, and annotated to post here, was taken on April 16, 2023 by the left navigation camera on the Mars rover Perseverance, and looks almost due west at the rim of Jezero Crater and the gap in that rim where the delta on which the rover presently travels poured through sometime in the distant past.

Near the center of the picture can be seen the helicopter Ingenuity, sitting where it landed after its fiftieth flight.

The overview map to the right provides the context. Ingenuity is the green dot, Perseverance the blue dot. The yellow lines indicate the approximate area covered by the picture. The red dotted line marks the planned route for Perseverance. Note how the rover has followed Ingenuity’s recent flight path almost precisely, moving to the north away from that red dotted line.

Ingenuity’s 51st flight is presently scheduled for tomorrow. The plan is to go about 600 feet to the west, landing approximately at the black dot.

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 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
