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.

ULA picks Aerojet Rocketdyne engine for Vulcan upper stage

Capitalism in space: ULA has chosen an Aerojet Rocketdyne engine to power the upper stage of its next generation rocket Vulcan.

The company has not yet made a decision on the engine for the first stage, where Blue Origin’s BE-4 still appears favored over Aerojet Rocketdyne’s AR-1 engine. This decision on the upper stage could partly be a political move, giving Aerojet the upper stage in order to make it easier to give the lower stage to Blue Origin.

ULA is forced to play politics here because politicians are involved. A number of power members of Congress want Aerojet Rocketdyne to get the business, and ULA risks offending these legislators should it abandon that company entirely.

    This would seem to make the selection of the BE-4 more likely. AR has now gotten a cut of the Vulcan pie, which should make losing out on the AR-1 more palatable to congressional stakeholders.

    As has been pointed out elsewhere, this isn’t the engine selection for ACES, this is just official contractual confirmation of what everyone knew, Vulcan is going to start off using a Centaur upper stage, which of course will use RL-10 engines. That said, they’re pretty clearly leaning towards sticking with the RL-10 for ACES, and this sets the ground for more dev work on the RL-10 to bring costs down.
