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

Ursa Major makes rocket engine deal with Air Force

Capitalism in space: Ursa Major announced today that the Air Force has awarded it a contract to test and qualify its Hadley rocket engines for future military space missions.

Ursa Major will also be providing the Air Force Research Lab with statistically significant data sets from extensive testing of multiple Hadley engines, including measurements of specific impulse, or ISP, combustion stability, vibration and shock profiles, and range of inlet pressures and temperatures.

Hadley will be qualified using similar metrics according to an internal test plan based on industry guidelines and best practices, focusing on engine life, operating space, functional requirements, and performance. The qualification test campaign under this effort will include runtime at and beyond the extremes of the power level and mixture ratio targets, demonstrating that Hadley operates safely and reliably within the power level and mixture ratio required for missions of DOD interest.

Ursa Major was founded by the engineers who developed SpaceX’s Merlin engine. It has already won a number of rocket engine contracts, including an order for 200 Hadley engines from rocket startup Phantom Space., and a contract with Northrop Grumman to replace the Russian-built engines on its Antares rocket with Ursa Major’s larger Arroway engine. [Ed: Ursa Major doesn’t have this contract, Firefly does. Ursa Major’s Arroway is simply comparable and competitive for the same business.]

Getting the Hadley engine certified by the Air Force will instantly make this engine more appealing to numerous rocket companies. In fact, it will make Ursa Major as a company more appealing. If this certification moves forward quickly, expect the Air Force to follow with a certification program for the larger Arroway engine. And if that occurs this engine might supplant other engines produced by Aerojet Rocketdyne and Blue Origin, especially because it appears that Ursa Major is using the same manufacturing philosophies of SpaceX, focusing not so much on design as assembly-line manufacturing, as shown by its 200 engine contract with Phantom.

Thus, it appears focused on producing many engines at less cost, and quickly.

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
