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

Ingenuity’s next flight set for today

Flight plan for Ingenuity's 10th flight
Click for full image.

Though circumstances can obviously change, the Ingenuity/Perseverance science teams have scheduled Ingenuity’s 10th Martian flight for sometime later today, with a flight plan, shown to the right, that is even more ambitious.

Flight 10 will allow us to reap the benefits of our previous flight. Scheduled for no earlier than this Saturday (July 24), Flight 10 will target an area called the “Raised Ridges” (RR), named for the geographic features that start approximately 164 feet (50 meters) south-by-southwest of our current location. We will be imaging Raised Ridges because it’s an area that Perseverance scientists find intriguing and are considering visiting sometime in the future.

From navigation and performance perspectives, Flight 10 will be our most complex flight to date, with 10 distinct waypoints and a nominal altitude of 40 feet (12 meters). It begins with Ingenuity taking off from its sixth airfield and climbing to the new record height. It will then head south-by-southwest about 165 feet (50 meters), where upon hitting our second waypoint, take our first Return to Earth (RTE) camera image of the Raised Ridges, looking south. Next, we’ll translate sideways to waypoint 3 and take our next RTE image – again looking south at Raised Ridges.

Imagery experts at JPL hope to combine the overlapping data from these two images to generate one stereo image. Flying farther to the west, we’ll try for another stereo pair of images (waypoints 4 and 5), then head northwest for two more sets of stereo pairs at waypoints 6 and 7 as well as 8 and 9. Then, Ingenuity will turn northeast, landing at its seventh airfield – about 310 feet (95 meters) west of airfield 6. Total time in the air is expected to be about 165 second.

Unlike the previous flights, this one will involve several turns while in the air. The engineers are definitely pushing the envelope with each flight, thus not only gathering scientific data about Jezero Crater but also advancing their engineering knowledge on the art of robotic flying on Mars.

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

    I wish they could fly it over to Opportunity and clean off her solar panels.

  • I’d rather they blew off Insight’s solar panels myself.

    Not sure what the helicopter’s maximum range from the Perseverance Rover is, but it ain’t enough to reach any other landed probe. Even though it is self-sustaining power-wise, it depends on its mother-ship for communications and control.
