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

A problem with drilling on Mars

In drilling a new hole while scientists considered Curiosity’s future route to Mount Sharp, the drill cut off operations prematurely.

Engineers think that the rock might have shifted during drilling, causing the robot rover to abort. They have ordered the rover to take a lot of pictures of the situation so they can figure out what happened.

I should note that engineers take a large risk every time they use Curiosity’s drill, as the design of the rover’s electrical system is such that the drill might short everything out while it operates. Thus, when I see a story about a problem with any drilling operation, I become very concerned. In this case, however, it appears to not be a problem with the rover itself.

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

    Even if there is nothing wrong on *Curiosity*, the terrain itself could threaten the mission when drilling. If you drill into ground where there is ice to melt, from friction heating, and that water mixes with the soil, you could easily get a clay that grips, or several other possibilities that leave the drill stuck in the ground. Is there a mechanism to eject the drill if it gets stuck in the ground?

    Too bad we don’t station our telerobotic operators a little closer.

  • Competential

    Yes, they can eject the drill bit. They even have a couple of drill bits in reserve, stored on the front of the rover, which the arm can change to if one would break. All systems seem to have back-ups. If a Martian train ran over Curiosity, it would still be able to work and do some science. It could loose four wheels and still move around. That rover will be with us for a decade.

    We might simulate real time telerobitcs on Mars from Earth! This is such a great idea, I hope it can be tested with Curiosity. Its operations are painfully slow today. If this works it could work 24/7 always with geolocists at its steering wheel, I recommend that you watch this talk:

    55 minutes into this lecture, the “Scarecrow” version of Curiosity is explained.
