Readers!

 

The time has come for my annual short Thanksgiving/Christmas fund drive for Behind The Black. I must do this every year in order to make sure I have earned enough money to pay my bills.

 

For this two-week campaign, I am offering a special deal to encourage donations. Donations of $200 will get a free autographed copy of the new paperback edition of Genesis: The Story of Apollo 8, while donations of $250 will get a free autographed copy of the new hardback edition. If you desire a copy, make sure you provide me your address with your donation.

 

As I noted in July, the support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.

 

In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

 

Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

 

Please consider supporting my work here at Behind the Black. You can support me either by giving a one-time contribution or a regular subscription. There are four 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 or subscription:

 

4. Donate by check, payable to Robert Zimmerman and mailed to

SpaceX launches 13 satellites for the Space Force

SpaceX early this morning successfully completed its second launch for the Space Force, lifting off from Vandenberg Space Force Base in California and placing another thirteen satellites of its Tranche-0 constellation into orbit.

The first stage completed its thirteenth mission, successfully landing back at Vandenberg.

This flight was SpaceX’s 61st in 2023, which matches the record it set last year, doing it in only eight months. With four months still left to go in the year the chances of SpaceX meeting its goal of 100 launches in the year still remains a possibility.

Furthermore, this was the 70th successful launch for the United States this year, which matches the record that the nation had set in 1966, and had been the record for the country until last year, when American companies (with help of one government launch) completed 85 launches. It seems last year’s record will be smashed without much problem.

The leaders in the 2023 launch race:

61 SpaceX
38 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 70 to 38. It also leads the entire world combined, 70 to 62, while SpaceX by itself now trails the rest of the world (excluding American companies) by only 61 to 62, with another Starlink launch is now scheduled for tomorrow.

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. from any other book seller, or direct from my ebook publisher, ebookit. 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 don’t care how many times I see it, watching the booster re-enter and then do the powered landing always gives me a thrill.

    Thanks again to Edward for his 8/29 comments regarding the need for “Entry” burns for RTLS F9 missions.

    For brevity, I’ll only show the entry burn telemetry from this RTLS and the last Starlink ASDS landing missions in the following table:
    kph km kph km
    speed alt speed alt
    entry start 4500 47 7950 62
    entry end 4200 32 5450 42
    5500 32

    To recap, at the speed is 5450 kph at the end of the ASDS burn at 42 km. I also included the velocity at 32 km. This is 1,000 kph faster than the beginning of the entry burn for a RTLS mission. I am still mystified why even a short entry burn is needed for a RTLS mission given these lower velocities at similar altitudes/air densities. I’m sure that there is a good reason but I’m not a SpaceX rocket scientist. Skipping the entry burn for RTLS missions could save some mass and wear and tear on the Merlins. I promise that this will be the last time I bring this up. :-)

    Excellent video perspective on this launch!
    It really gives you a sense of height & speed.
    (As much as I do enjoy watching the 2nd stage engine glow orange, no great loss not seeing the 2nd stage and payload this time around.)

    FYI…

    Mr. Zimmerman is mentioned prominently in an article at The Hill website today regarding SpaceX and the federal government. Interesting stuff…
