Another study says Mars does not have liquid water under its south pole
The uncertainty of science: A new study now claims that the presumed detection of lakes of liquid water under the Martian southern polar ice cap in 2018 was likely wrong, and that the detection was more likely volcanic rock.
The researchers think their conclusion — volcanic rock buried under ice — is a more plausible explanation for the 2018 discovery, which was already in question after scientists calculated the unlikely conditions needed to keep water in a liquid state at Mars’ cold, arid south pole.
“For water to be sustained this close to the surface, you need both a very salty environment and a strong, locally generated heat source, but that doesn’t match what we know of this region,” says the study’s lead author, Cyril Grima, a planetary scientist at The University of Texas at Austin Jackson School of Geosciences.
So my readers know how uncertain all of this is, note that the 2018 discovery of underwater liquid water was later confirmed by other scientists in 2020, then rejected by different researchers in 2021, who claimed it was clay instead.
In other words, the scientists have some inconclusive data that could mean many different things, either water, clay, volcanic rock, or maybe something else that someone hasn’t yet suggested. To really answer the question will require far more data, with some like required in situ on Mars itself.
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 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

Anyway to get a paper copy of your new book? I’m a Luddite but I very much want a copy. I’m happy to buy direct somehow to maximize your profit.
Thanks! I’ll check back here or feel free to email me at the email I put in below.
Jennifer: I assume you are asking about Conscious Choice. Unfortunately, no paper version presently exists, only the ebook.
I am like you. I prefer to read real physical books. However, I do read ebooks if that is the only option, and the book is worth reading. As I told another reader recently whose eyes were mediocre (like mine), the advantage of an ebook is that you can instantly increase the size of the font, making it easier to read. I suggested he give it a try and he responded back that he would. He then bought Pioneer.
I say the same to you. Give it a try.
Regardless, thank you for your interest and support.
