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.

InSight hits a rock

Engineers have called a pause in InSight’s drilling operation to insert a heat sensor as much as 16 feet into the Martian soil because it appears the drill has hit a large obstruction.

It penetrated to a depth between 18cm and 50cm into the Martian soil with 4,000 hammer blows over a period of four hours, explained Tilman Spohn, HP3’s principal investigator from the German space agency (DLR). “On its way into the depths, the mole seems to have hit a stone, tilted about 15 degrees and pushed it aside or passed it,” he added. “The mole then worked its way up against another stone at an advanced depth until the planned four-hour operating time of the first sequence expired.”

Prof Spohn said there would now be a break in operations of two weeks while the situation was assessed.

When these facts were first reported on March 1st, the press release did not make it clear at that time that the hammer drill was actually blocked. If it cannot drill down further, this will put a crimp in the heat sensor’s ability to measure Mars’s internal temperature. Right now it is only about a foot down, which on Earth would still have it influenced by surface temperatures.

    If you intend to pound something fifteen feet into the soil, shouldn’t you anticipate encountering rocks and have a plan to overcome them? Apparently, this minor detail escaped the genii at NASA.
