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.

    An interesting article. Especially when compared to the article linked to below.

    Both quote supposed details of contracts for delivery of cargo service to the ISS. Assuming these articles are both accurate (and both companies can meet the terms of the contracts). A comparison can now be made between the two service providers.

    Space X
    – Number of flights – 12.
    – Contract cost – $1.6 Billion.
    – Up mass per flight – 7,300 lbs.

    Based on these figures the following metrics can be derived:
    – Cost per flight (rounded down to the nearest million dollars) – $133 Million.
    – Total payload delivered (rounded up to nearest metric ton) – 40 Metric Tons.
    – Cost per pound to delivered payload (rounded down to the nearest thousand dollars) – 18,000/lb.

    Orbital Sciences
    – Contract cost – $1.9 Billion.
    – Total payload delivered – 20 Metric Tons.

    Based on these figures the following metric can be derived:
    – Cost per pound to delivered payload (rounded down to the nearest thousand dollars) – 43,000/lb.

    This (obviously) makes Space X look much better than Orbital Sciences in terms of cost.

    However, there is (to me at least) an even more interesting point. Orbital Sciences (to the best of my knowledge and to there credit) has made no grandiose claims, but Space X has talked of revolutionary reductions in launch costs (Elon Musk has even asserted that he will be selling round trip tickets to Mars for $500,000/ticket by 2030). Even the Space X figure in an actual contract comes nowhere near supporting such claims. The $18,000/lb. figure is extraordinary only in how ordinary it seems.
