My February birthday fund-raising campaign for this website, Behind the Black, is now over. Despite a relatively weak initial three weeks, the last week was spectacular, making this campaign the second best ever.

 

Thanks to every person who donated or subscribed. It continues to astonish me that people who can read my work for free like it enough to donate money voluntarily. Words cannot express my appreciation for that support, especially in these uncertain times.

 

If you have been a regular reader and a fan of my work and have not yet donated or subscribed, please consider doing so. I take no ads, I keep the website clean from pop-ups and annoying demands (most of the time). Thus, 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

Curiosity’s mountainous view

Curiosity's view uphill on June 23, 2021

The travels of Curiosity at the base of Mount Sharp continue. In the past week, since my last update on June 16th, the rover has moved west past the entrance to Gediz Vallis to now sit at the base of Raphael Navarro Mountain, as shown by the panorama above. To get a sense of how far the rover has traveled in the past week, compare this panorama with the one posted then. It is also clear now that they are slowly returning to their planned route, and will not push up into Gediz Vallis as I speculated in that post.

The panorama is created from three photos taken by Curiosity’s navigation camera, found here, here, and here.

The map below the fold gives the context.

I have annotated the interactive map that the Curiosity team provides. The yellow lines indicate the area covered by the panorama above. The dotted red line marks their planned route up Mt. Sharp. The white line the route they have taken, through June 21st. The white dot almost due south of their present position and inside Gediz Vallis is a suspected recurring slope lineae, a streak that darkens seasonally that might be caused by the seepage of underground brine.

The rover is presently higher on Mount Sharp than any time previously, with that record being broken with almost every day’s travel. Over the next few months they will circle around Navarro Mountain to head uphill on its western side, making a side trip back to check out Gediz Vallis Ridge before driving into Gediz Vallis.

As I have mentioned previously, these are the first Martian mountains seen from eye level. More such breath-taking views await us as Curiosity dives upward into Mount Sharp.

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
