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


Weird flat plateau on Mars

Weird flat plateau on Mars

Cool image time! The image to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on December 15, 2020, and was actually a follow-up observation from an earlier image taken by the camera on Europe’s Trace Gas Orbiter (TGO), according to Dr. Livio Tornabene of the University of Western Ontario. As he explained in an email:

The team is rather polarized with their verdict on what exactly the feature is… while at first glance it appears to be a lava flow, it very well could be that these deposits eroded to yield this flow/lobate like appearance and isn’t lava at all. So as someone that is both involved with [TGO] and [MRO], I noticed that the lobate feature causing quite the debate had no coverage from [MRO].

It appears that some scientists think that instead of lava, this is a mud flow. Research presented [pdf] during the 2019 Lunar & Planetary Conference in Texas found evidence that mud could flow like lava under the right conditions.

At this point neither Tornabene nor anyone working on the TGO team have yet analyzed this new MRO image to see if they can answer this question. That this feature is located in a region just to the southeast of Marineris Valles where there is evidence both of volcanic activity and sedimentary deposition, makes answering the question even more challenging.

The data from TGO indicated [pdf] that the plateau was about 30 to 65 feet thick. Based on crater counts the age is thought to be between 1.6 to 1.9 billion years old.

What struck me about the plateau is that though it really does look like a flow, it also appears remarkably flat and smooth. Even more puzzling is that, according to the TGO paper, the plateau slopes downhill very gently (a 1% grade) to the south, not to the north as suggested by the shape of the flow. Maybe later geological events tilted the entire feature after it solidified, thus changing the grade?

Meanwhile that channel near the bottom of the image crosses through the grade and the flow, as if it was cut after the flow was placed. In other words, the flow and channel were formed separately, at different times.

Ah, the mysteries of planetary geology. If only we could just go there with a geologist’s hammer. These questions would then be so much more simple to answer.

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. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.

 

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. Even today NASA and Congress refuse to 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.

    Obvious as it is to say it, regardless what the remote interpretations are of the geological formation of mars, we simply have to go there in person.
    Every day I’m more impressed and more a believer in what Musk & SpaceX is aiming for. It’s the grand imperative. As Larry Niven and Dr. Jerry Pournelle use to say, “It’s raining soup in space!”
    I miss Jerry Pournelle more each day that passes.

    Great blog Mr. Zimmerman! Been a lurker long time, really appreciate you and you hard work and thoughtfulness.

    I sure miss Jerry Pournelle more each day that passes.
