Conscious Choice cover

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.

    In part 1 I believe the term you wanted was “observational data”. I have been listening to JB since 2005 and it’s where I discovered BTB.

    Insight has discovered something interesting, and completely unexpected, about Solar eclipses on Mars. Although the tiny 11 km diameter Phobos only shades about a third of the Sun for half a minute, the Martian ground temperature in the shadow immediately drops and thus the crust shrinks a bit, which Insight’s seismometer has measured. The effect during a dust storm should be even greater. Such oscillations might cause proper Mars quakes. A phenomena not observed on Earth because our thicker atmosphere keeps the ground temperature more stable during eclipses.

    Anton Petrov is a bit comical “Hello wonderful person!” But he has a formal education in astronomy and plows through recent astronomy papers, that he links to:

    I on the other hand discovered John Batchelor Show because of Robert Z. And I’ve recommended it to many who have an interest in international security policy and US politics. He’s a damn good radio man with damn good guests!

    Re: Three Vulcan launches on short schedule for Dynetics

    A friend of mine who works the range at the Cape – who is, I should add, a big fan of ULA – was fairly dumbfounded when he heard about this plan to launch three Vulcans within “14-20 day centers.” From what I can make out, ULA has never managed turnaround on SCL-41 in less than 29 days, which looks to be, I think, something they did only once.

    Now, it is true that ULA has a second pad (SLC-37) at the Cape that perhaps COULD be used; but it’s configured only for Delta IV Heavy, and the current plan is for ULA to wind it down rather than rebuild it for Vulcan. So unless that changes, that’s out.

    This is not to say it is *impossible* that ULA could do this. But it would take, at minimum, a 2 shift workforce, which is a lot of extra payroll for ULA. I guess they could just send the bill to NASA, but oe hopes that isbeing mde clear up front. Suddenly, those Vulcan launches start getting more expensive….

    It should be noted that the three launch Vulcan architecture is only needed on the initial mission; after that, the lander is already up there to be reused, and then you’d just need two launches, to bring up the fuel.
