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

Was Yutu stopped by rough ground?

One of the designers of the Chinese lunar rover Yutu said in a news interview today that the rocky nature of the Moon’s surface, far rougher than expected, was what caused it to stall.

The rover was tested in Beijing, Shanghai and the desert in northwestern China before its launch, but the terrain of the landing site proved to be much more rugged than expected, said Zhang Yuhua, deputy chief designer of the lunar probe system for the Chang’e-3 mission. “It is almost like a gravel field.”

Data from foreign researchers projected that there would be four stones, each above 20 cm, on average every 100 square meters, but the quantity and size of the stones that Yutu has encountered has far exceeded this expectation, Zhang said in an exclusive interview with Xinhua. “Experts’ initial judgement for the abnormality of Yutu was that the rover was ‘wounded’ by colliding with stones while moving,” she said. [emphasis mine]

The implication of the highlighted quote is that it isn’t their fault, it was the fault of those evil Americans and Russians who incorrectly estimated the roughness of the ground. This article also doesn’t fit the information released when Yutu first stalled, where they explained that their problem was partly an inability to retract equipment in preparation for lunar night. While this story could be true, it isn’t the whole story.

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

    That’s ridiculous. They filmed the site themselves from the lander. And the Russian rovers 40 years ago worked just fine for miles and miles. And didn’t Yutu fail while standing put, because it couldn’t fold its solar panels? A very very slow collision with a 20 cm rock shouldn’t devastate the whole frame of a lunar rover. As usual, I suspect that the translation from the Chinese is way way off. Do they mean dust instead of rocks?

    Surprised that the Chi-Coms did such a poor job on stealing the data needed to do Lunar Surface Re-Con…
    Usually, they are on top of that sort of thing. Hope they did a better job stealing the secrets need for building Nuke Subs, or else, shades of the USS Thresher….
