Conscious Choice cover

Now available in hardback and paperback as well as ebook!


From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.


“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.


All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.


Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

    Robert wrote: “This is one of China’s interior spaceports, so they apparently recognize that their rocket stages can fall on someone’s head, and are proud that in 2022 they avoided any such tragedies. Well, bully for them.

    This is a good thing. It shows that they care. Right up until there is an injury or casualty, then they are likely to just say “oops. Better luck next time.”

    The Z-man asked;

    “The fundamental question remains: How could liquid water have been there in a climate that is too cold and an atmosphere too thin?”

    The evidence for flowing liquid is everywhere. (we assume it’s water). At one time I would not have believed it, until the pictures from the satellites started coming back.

    The way Mars is today, is not how it has always been.

    I have believed for a long time the hypothesis that the collapse of our mostly oxygen atmosphere
    into water, killing the dinosaurs, and the beginning of the “ice ages” was triggered by of cloud of gas from the local chimney, perhaps from a supernova, similar to the dust between us and the center of our own galaxy.
    It passed through changing our solar system forever, adding vast amounts of hydrolyzed carbon (methane) and hydrolyzed nitrogen (ammonia) as well as other light gases on all the planets in our solar system. (adding mass to all the planets and ice to the outer moons)
    Europa is much smaller than Mars, and yet is the said to have a large amount of liquid under the ice.
    There’s good evidence that Mars was once completely covered in similar ice, and because of it’s proximity to the sun, it’s once thicker atmosphere and volume has blown away with the solar wind.
    All that’s left is the ice caps.

    If there was liquid under the ice slushing around with every rotation, it would explain why there’s no shoreline, (except maybe the cliffs that’s around some of the volcanoes) and extreme erosion of the canyons and bare rock formations that wind alone cannot explain, especially in a low density atmosphere.
    As the liquid under the ice froze, becoming glacier, it was just a matter time before it all evaporated away and left the planet… Except for what sunk deep below the sand.
    Perhaps there wasn’t much water that was liquid, much of the impact craters survived except in the northern hemisphere.
    Just guessing with a lot of imagination…

    By the way, Zhurong went to hibernation a year ago and hasn’t woken up… It might be dead.
