Readers!

 

My July fund-raising campaign to celebrate the fifteenth anniversary since I began Behind the Black is now over. I want to thank all those who so generously donated or subscribed, especially those who have become regular supporters. I can't do this without your help. I also find it increasingly hard to express how much your support means to me. God bless you all!

 

The donations during this year's campaign were sadly less than previous years, but for this I blame myself. I am tired of begging for money, and so I put up the campaign announcement at the start of the month but had no desire to update it weekly to encourage more donations, as I have done in past years. This lack of begging likely contributed to the drop in donations.

 

No matter. I am here, and here I intend to stay. If you like what I do and have not yet donated or subscribed, 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

Chinese pseudo-company successfully completes rocket hop test

The Chinese pseudo-company Landspace successfully completed a rocket hop flight of its Zhuque-3 prototype hopper yesterday, testing vertical take-off and landing in preparation of recovering and reusing the first stage of its rockets.

The hop itself went to 350 meters and performed a small translation maneuver to the landing pad. The hope is called “ZQ-3 VTVL-1” which refers to “Vertical Takeoff – Vertical Landing”. It uses a single TQ-12 methane engine, which is also used on the current ZQ-2 rocket. The engine can throttle between 50-110% of the normal 80 tons of thrust, giving it a throttle range between 40 and 88 tons. The performed flight went on for roughly 60 seconds. The weight of the hopper is 50.3 tons.

Landpace confirmed the landing precision with 2.4 meters, with a landing speed of 0.75 meters per second, at a pitch angle of roughly 0.14 degrees, and a roll angle of 4.4 degrees. The hopper survived the hop and is already being inspected after the flight.

Video of the hop can be viewed at the link. The hopper is almost identical in concept to SpaceX’s Grasshopper test vehicle used by that company, flying with one engine of the same type used in its operational rocket.

If their test program continues as planned, Landspace hopes to begin flying reuseable stages in 2025, with that first stage capable of flying 20 times.

Of all the pseudo-companies in China, Landspace appears to be the most successful. It not only has an operational orbital rocket, Zhuque-2, that has carried satellites into orbit twice (here and here), it is very close to achieving rocket reuseability competitive with SpaceX.

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
