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.

    This is duplicating the work of the DC-X. Is it really worth sacrificing payload for the landing fuel needed as opposed to using a parachute? Considering the price per pound of orbited mass, is the upper stage worth the fuel costs to recover it?

    this is cool, but Nova is on with a segment on the planet Mars, and i planned an evening alone with the 1955 movie “Conquest of Space”. wow, the rockets in this movie Operate just like ….wait a minute! 1955 ?

    DC-X and Grasshopper are in no way analougous. Grasshopper is using a Merlin 1D a 145,000 lb thrust engine, on a full size (but not fully fueled) first stage, 150 feet or so tall.

    DC-X was a 39 foot tall 13,000 lb thrust (I recall it having 4 RL-10’s so the Wikipedia entry may really mean 13K X 4).

    These are NOT the same thing.

    This is a literal first stage of a production rocket, testing out how it would behave for vertical powered landing.

    DC-X was nice, but in a different order of magnitude smaller world. Things do not scale linearly in this space.
