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.

Martian lava flooded crater?

A quick cool image! The photo to the right, rotated, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) more than a decade ago, on June 1, 2010. I post it now because it is today’s MRO picture of the day, and is definitely cool. The caption:

One of a few “scaly-looking” inselbergs within regional platy-ridged flows in Elysium Planitia. This inselberg has a broken and blocky appearance with some of the blocks being tilted. Could this be the remnant of a once extensive mantling deposit? An inselberg is an isolated hill or mountain rising abruptly from a plain.

The wider image by MRO’s context camera below, also rotated, cropped and reduced to post here, illustrates even more forcefully how isolated this circular set of blocks is.

Overview map

The circular feature is on the top right, sitting isolated on a very very smooth plain. To the south is another set of isolated blocks, this time not showing any obvious circular pattern. Both appear to be material that has been partly buried by flood lava. The circular feature suggests it is a partly buried and eroded ancient crater.

Make sure you take a look at the full images. Both emphasize how isolated these features are on that flat lava plain. To the south can also be seen a number of single small peaks, sticking out from that plain.

The overview map to the right marks this image’s location by the white cross, sitting inside the Athabasca Valles flood lava plain. This lava flood, about the size of Great Britain, is thought to be one of the youngest on Mars, with an estimated age of between half million to ten million years. It is also believed that it was laid down in only a matter of weeks.

Yet, are these buried features, or are they geology that formed after the flood lava was laid down? The southern collection of blocks appears to resemble chaos terrain, terrain that is seen in many places on Mars and is created by erosion cutting away material along fault lines.

Then again, why have erosion only at these isolated spots, and not across the entire plain?
