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.

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:

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’s upcoming travel plans

Overview map
Click for interactive map.

Today’s update from the Perseverance’s science team provided a rough outline of their travel and drill-sampling plans for the Mars rover in Jezero Crater as it begins its climb up onto the delta that once poured into the crater. The route they plan to travel initially is dubbed Hawksbill Gap.

At Hawksbill Gap, however, we may instead carry out the first portion of the sampling sol path (which includes abrasion and collecting observations using our proximity science instruments) at up to 5 locations along our ascent. After that, we’ll turn around and begin a descent back down Hawksbill Gap and collect rock core samples at 3 of our abrasion locations.

This modified sampling strategy is intended to provide the team with valuable contextual information as we climb Hawksbill Gap and interpret the delta stratigraphy around us. With proximity science data in-hand, we can down-select our sampling sites to ensure we’ll be collecting the most scientifically valuable cores along our descent. Of course, we still maintain the option of collecting sample cores at any point during our ascent, if the team decides a particular abrasion site warrants immediate sampling.

The map above shows my guess (the red dotted lines) as to their potential routes uphill. As the science team has so far not published a map indicating exactly where Hawksbill Gap is, I can only guess at this point. The blue dot indicates Perseverance’s present position, the green dot Ingenuity.

As for the helicopter, there is no word yet whether the engineers have successfully gotten its batteries back to full charge. Until then, it cannot fly, and is also at risk of freezing up in the cold Martian winter.

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
