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.


SpaceX launches 21 more Starlink satellites

SpaceX this morning successfully launched another 21 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its thirteenth flight, landing on a drone ship in the Pacific.

The leaders in the 2024 launch race:

93 SpaceX
39 China
11 Russia
10 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 108 to 61, while SpaceX by itself now leads the entire world, including American companies, 93 to 76.

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

    Not sure if it is just my imagination, but I watch every F9 launch and landing, and it seems to me that the landings are getting more like near-bullseyes every time.

    Ray–
    Interesting observation.

    In-general, do we know the mean circular error for these landings?

  • Ray Van Dune

    FWIW, Co-Pilot chat says it is 1-5 meters. This does not sound like a CEP value, but a typical range, and I could not find the data behind it, or any other reference.

    For catching Superheavy, if we assume say 3 meters, and the diameter of the stage is 9 meters, this seems insufficiently accurate to avoid damaging the hull of the booster.

    Could SpaceX have supplemental short-range guidance sensors built into the chopsticks? Looks like it might be needed.

  • Dick Eagleson

    Super Heavies, like F9 1st stages, have cold gas nitrogen thrusters to handle fine adjustments to vehicle position at the very low speeds and altitudes just before landing when the grid fins no longer have enough control authority.

  • Ray Van Dune

    Dick, thanks, didn’t know that they had those thrusters, but having them is one thing and having the precise location of the vehicle (to < 1 meter?) is another. That's what is concerning me.

  • wayne

    Ray-
    I’d modify my pondering, because these are guided landings, we just don’t know the fine tolerances involved.
    As to precise location, do they use GPS or that ground based doppler stuff? (don’t know what it’s called)
