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.

Japanese scientists complete inventory of Ryugu asteroid samples

In a press conference yesterday the Japanese space agency JAXA announced that scientists have completed their inventory of the samples brought back from the asteroid Ryugu by the Hayabusa-2 spacecraft, and are now ready to begin distributing those samples to scientists around the world for more detailed research.

JAXA has cataloged the soil samples brought back by Hayabusa 2 last December, by size, color and shape. From now, 269 researchers from 14 countries, including Japan and the United States, will conduct an in-depth analysis of the soil’s structures and components over the course of about a year.

As expected, the inventory found the samples had a large amount of hydrogen, oxygen, and carbon atoms. Even before Hayabusa-2’s arrival, Ryugu had been catalogued as a “hydrated” asteroid, which means it was thought to contain a lot of hydrogen and oxygen, the basic elements of water. The inventory has now confirmed this.

    Hydrogen and Carbon atoms make the sort of Hydrocarbons that would be found in the kerogens. These, under pressure and heat, generate oil and gas here on Earth, and would be excellent precursors for Methane at an asteroid. It will be interesting to see what the Oxygen is combined with, and how volatile each of these combinations is.

    The presence of Hydrogen in the shallow near-surface deposits that could be reached by Hayabusa makes for some optimism about volatiles being retained by Near Earth Objects that are easy to reach from high Earth orbits by ion-propelled space tugs. Now, if we can just get samples from several meters *below* the surface, we’ll know if we can get mines for water ice and carbonaceous volatiles set up, and how expensive that will be. I remember the Chinese were planning a mission to 2016 HO3, and I wonder how deep their samples will be taken from.
