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

SpaceX about to set reuse record for fastest turnaround ever

Capitalism in space: If tomorrow’s launch of a South Korean military satellite by SpaceX’s Falcon 9 rocket succeeds, it will set a new all-time record for the fastest turnaround of a used rocket, 44 days.

The previous record was 54 days, set by the space shuttle Atlantis in 1984. The article notes however the spectacular differences:

By far the most impressive aspect of Falcon 9’s imminent record is the comparison between the resources behind Space Shuttle Atlantis’ 54-day turnaround and Falcon 9 booster B1058’s ~44-day turnaround. Around the time NASA and Atlantis set the Shuttle’s longstanding record, some 5000-10000 full-time employees were tasked with refurbishing Space Shuttles and the facilities (and launch pads) that supported them. Based on retrospective analyses done after the STS program’s end in 2011, the average Space Shuttle launch (accounting for the vast infrastructure behind the scenes) ultimately wound up costing more than $1.5 billion per launch – more than the Saturn V rocket the Shuttle theoretically replaced.

According to a uniquely detailed May 2020 AviationWeek interview with SpaceX CEO Elon Musk, Falcon 9 booster turnaround may cost as little as $1 million apiece and can be managed from start to finish by several dozen employees at most. In other words, even though SpaceX boosters are suborbital and stressed quite a bit less than orbital Space Shuttles, Falcon 9 reuse is approximately a thousandfold more efficient that Space Shuttle reuse. [emphasis in original]

I should add that SpaceX also has three more launches on tap for the rest of July. If all lift off, the company will have launched four rockets in only three weeks, which in itself will be a record. No private rocket company has ever launched so frequently and so routinely. And only Russia during its Soviet Union heydays has come close to launching with this frequency.

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

    The shuttle was an incredibly impressive achievement with 1960s technology, but it was never economical. It was a quintessentially American vehicle, our Suburban to space. Big, rugged, and room to take 7 passengers and all the toys and supplies on two week road trips, but mileage was decidedly poor. No matter, it did its job and was something to be proud of.

    But materials and computer science are not static, and Musk recognized that 50 years of progress by both made possible what was previously fantasy, Buck Rogers spaceships that take off AND land. And with his business acumen he realized how economical and transformative that would be (like enabling10,000 satellite constellations to connect the planet).

    We all applauded the shuttle, but we’ll all benefit far more in the years ahead because of SpaceX.
