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.

    Did I read the thing wrong on the BE-4? I read a test firing a week but not building one per week.

  • john hare: I noted that you had to scroll down and read the tread. In response to questions Bruno suggests this.

  • siriusactuary

    There does not appear to be a link on the JAXA article.

  • siriusactuary: Sorry about that. Link now added.

    Reading the times on the replies, it appears that the question was asked 2 December and answer was to a different question on 1 December. Not normally reading Twitter, perhaps I misunderstood the comment method there.

  • john hare: I admit to my own willful ignorance of Twitter and its ways. However, at the link that Jay provided, when I posted, if you scrolled down to the most recent previous tweets in the thread, Bruno was asked was Blue Origin producing an engine a week and he responded yes. Jay himself interpreted it that way, saying so when he sent me the link.

    It is possible that by the time you looked, Twitter had moved on, and this exchange was no longer visible. I unfortunately am not the one to ask. I will ask Jay to clarify.

    John Hare,
    Mr.Bruno’s comment was implying that they, B.O., were building one BE-4 a week since they were testing a BE-4 every week. The B.O. factory in Kent, is not producing an engine a week. A lot of people on other forums were also commenting on that post.

  • Edward

    Jay and John hare,
    It will be a couple of years or so before Blue Origin will need to build fifty engines each year, but I would not be surprised that these early engines are continuing to undergo extensive testing before delivery.
