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

April 16, 2021 Zimmerman/Batchelor podcast

Embedded below the fold, in three parts. All three segments tonight are almost entirely about commercial space, with the third segment a special one that John and I taped today following today’s decision by NASA to give SpaceX the lunar landing contract.

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

    Jim Cantrell is back again. I hope they take a very different approach with this rocket company. Hopefully not a phantom.

    Bob, your statement, “it’s going to make the … space station orbit pretty crowded …”, made me blink.

    From Douglas Adams, “Space is big. Really big. You just won’t believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space, listen…”
    ;)

  • Icepilot: I was being metaphoric. I very well know that there is plenty of space in space for a lot of space stations.

    John Batchelor asked, “why don’t we see a lot of cool crashes from Bezos’s company the way we do from Musk’s?”

    Robert’s answer is good. There may have been a lot of problems that we didn’t see in the early years.

    The main reason that New Shepard no longer has spectacular crashes is that it is in verification phase of development, a phase in which spectacular failures are very bad, and Starship is still in basic technology proof of concept phase, when failure is to be expected. The methods and technologies for New Shepard are fairly well known but for Starship they are still being explored. They are in very different phases of development. New Shepard should be close to its final design, but Starship is still finding out how to do completely new maneuvers and techniques with new concepts, technologies, and methods. New Shepard should look routine, Starship should not, yet.

    Super Heavy is designed to operate similarly to the Falcons, so it should not have spectacular failures (unless they do a test to failure pressure on their first test article). That technology is reasonably well known.

    Another difference, similar to Robert’s answer, is that when New Shepard had a spectacular failure on its first booster landing, Blue Origin was not forthcoming of the video of the crash. SpaceX does not have large areas of real estate to keep the general public away from its tests, so much of what SpaceX does ends up being seen by the public. Operations at the Boca Chica site are so popular that there are even people making videos of the manufacturing process and of moving hardware from one location to another. SpaceX’s processes (assembly, integration, test, as well as the construction and operation of ground support equipment and assembly buildings) are the most watched that I have ever known.

    Although SpaceX is very willing to suffer spectacular failures in order to advance their technologies, they do not go out of their way to have them. SpaceX sounded very glad that their first high altitude flight succeeded in its first pitch-over at altitude. They are skipping three test articles in order to go straight to the next major iteration of their design, which suggests to me that they were expecting some failures learning how to perform that first pitch-over maneuver. It is because they learned so much so fast that has enabled them to skip three test articles.

    New Shepard is far enough along that they are verifying that their hardware, software, and procedures really do what they want them to do. They are likely not making major changes between test flights but are making iterative changes to their final methods.
