Readers! A November fund-raising drive!

 

It is unfortunately time for another November fund-raising campaign to support my work here at Behind the Black. I really dislike doing these, but 2025 is so far turning out to be a very poor year for donations and subscriptions, the worst since 2020. I very much need your support for this webpage to survive.

 

And I think I provide real value. Fifteen years ago I said SLS was garbage and should be cancelled. Almost a decade ago I said Orion was a lie and a bad idea. As early as 1998, long before almost anyone else, I predicted in my first book, Genesis: The Story of Apollo 8, that private enterprise and freedom would conquer the solar system, not government. Very early in the COVID panic and continuing throughout I noted that every policy put forth by the government (masks, social distancing, lockdowns, jab mandates) was wrong, misguided, and did more harm than good. In planetary science, while everyone else in the media still thinks Mars has no water, I have been reporting the real results from the orbiters now for more than five years, that Mars is in fact a planet largely covered with ice.

 

I could continue with numerous other examples. If you want to know what others will discover a decade hence, read what I write here at Behind the Black. And if you read my most recent book, Conscious Choice, you will find out what is going to happen in space in the next century.

 

 

This last claim might sound like hubris on my part, but I base it on my overall track record.

 

So please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. I could really use the support at this time. 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. Takes about a 10% cut.
 

3. A Paypal Donation or subscription, which takes about a 15% cut:

 

4. Donate by check. I get whatever you donate. Make the check payable to Robert Zimmerman and mail it 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.


A FAA waiver granted to SpaceX for its next launch outlines details on the company’s effort to recover the first stage for reuse.

The competition heats up: A FAA waiver granted to SpaceX for its next launch outlines the details of the company’s effort to recover the first stage for reuse.

The first stage will coast after stage separation, and then perform an experimental burn with three engines to reduce the entry velocity just prior to entry. Prior to landing in the water, it will perform a second experimental burn with one engine to impact the water with minimal velocity. The second stage will coast and then perform an experimental burn to depletion.

Elon Musk has said that they will be experimenting with bringing the first stage back safely with each launch of the upgraded Falcon 9 rocket. This waiver now gives us the plan for the first launch. It also shows that they are also considering recovery of the second stage as well.

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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

  • So, does an inversion layer cause an increased risk to the rocket or is this just a function of if the rocket explodes that there is more collateral damage on the ground?, very interesting, I never realized that something as simple as an inversion layer would have an impact on a launch!

    At a guess, this is not because of the Falcon 9, which burns LOX and Kerosene, but because the Dragon still uses the old Nitrogen Tetroxide/Hydrazine combination for its attitude control thrusters. Hydrazine is a deadly poison that kills people when Protons crash in Kazahkstan too near a village. Nitrogen Tetroxide cleverly settles on the mucous membranes of your throat and lungs, and reacts with the water there to make nitric acid.

    Anything with several hundred kilos of that combo is cause for worrying about an inversion layer getting the vapors from an explosion trapped near the ground. They are hypergolic, and react so fast that 2 large volumes of them smacked together will react at the surface hard and fast enough to blow the vast bulk of it into two separate clouds, both of them deeply unfriendly to anything living.

    I could really wish the newer NOFBX monopropellants with performance equal to Hydrazine/Nitrogen Tet. were certified when the design of the Dragon started.

  • Tom,

    You might be right in general, but the waiver was specifically for the next Falcon 9 launch, which will not have Dragon on board.

  • Tom Billings

    Yup! Gotta watch that more carefully. Shrouds are *not capsules! :-)
