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.

Off caving

Because I am off on a caving project this weekend in the mountains where there is no internet service, I will not be able to approve comments or post anything until I return on Sunday.

The next few days should be most interesting, as there are SpaceX and ULA launches scheduled. The SpaceX launch tonight will place a secret government satellite in orbit while trying to land its first stage. The ULA launch on Saturday will be the last launch for its Delta 2 rocket, which the company is retiring because it costs too much to operate.

    I know virtually nothing about spelunking. Do you drill in dynamite to blow up free passages of access to blocked parts of the caves?

    When you return from radio silence, this is what you have missed (Trump drank water):

    I feel like going down in that cave I happen to have nearby where I live. And stay there for contemplation about the world above.

    Regarding the Delta-II launch, this JPSS-1 mission is its penultimate launch. The final Delta-II mission will be to loft NASA’s ICESat-2, currently scheduled for September 2018.

    Here is the NSF thread for that mission:

    My Father was a world class caver back in the 60’s and 70’s , and he took me on a few light trips when I was a lad…
    The procedure back then was digging and light explosives were fine when gaining entry to a cave from the surface, and digging was ok inside the cave as long as you didn’t mess up natural formations too much. I presume etiquette has not changed too much in the intervening years..
    Back in those days there was no rope strong, light and non-stretchy enough for long decents, so they dragged 30′ sections of wire rope ladder with them and hooked them together, and no good battery tech, so lighting was provided by carbide lamps..
    As the club photographer my father also had to carry his camera gear with him in ammo tins!
    Apparently the club motto was “If you ain’t hard… you shouldn’t have come” ?
    Good luck on your mission Bob!
