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.

SpaceX has test fired its Grasshopper replacement test vehicle.

The competition heats up: SpaceX has test fired its Grasshopper replacement test vehicle.

Unlike Grasshopper, which only had one engine, the Falcon 9R (pronounced “niner”) is the equivalent of a Falcon 9 nine engine first stage. They fired it on the launchpad for 5 seconds in preparation for future vehicle take off and landing tests.

    I’m only about 150 miles from there (eastern AZ.) I should make a trip!

    Actually, the Grasshopper 2/F9R being tested only has three engines installed at the moment, the others are to come later. More than the original Grasshopper which means sufficient thrust to carry a heavier load to higher altitudes for testing, but not yet a complete first stage.

  • I am assuming you are right. The reason I assumed it was a full first stage is because the article talks about developing a full thrust of 1 million to 1.5 pounds (depending on altitude), which I thought was what the first stage did. Am I in error again?

    You are correct that it WILL eventually have all 9 engines, the config being tested at McGregor apparently only has three engines. At some point they will install the other 6 for testing in New Mexico. Exact details are of course scarce.

    Otherwise it is supposed to be a full up first stage.

    Have you seen a cost quote per engine? It would be interesting to know what Spacex is considering the cost to build a Merlin 1D. One of the changes quoted for the 1D build is simpler, and cheaper to build. Wonder how much difference between 1C and 1D there is.
