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.

A spot on Mars, as seen by different orbiters over the past half century

Mars as seen over the past half century

The science team of Mars Reconnaissance Orbiter (MRO) have assembled a collection of images of the same location on Mars that were taken by different Martian orbiters, beginning with the first fly-by by Mariner 4 in 1965 and ending with MRO’s HiRise camera. The image on the right, reduced in resolution to post here, shows these images superimposed on that location, with resolutions ranging from 1.25 kilometers per pixel (Mariner 4) down to 50 meters per pixel (MRO).

This mosaic essentially captures the technological history of the first half century of space exploration in a single image. Mariner 4 was only able to take 22 fuzzy pictures during its fly-by. Today’s orbiters take thousands and thousands, with resolutions so sharp they can often identify small rocks and boulders.

The mosaic also illustrates well the uncertainty of science. When Mariner 4 took the first pictures some scientists thought that there might be artificially built canals on Mars. Instead, the probe showed a dead cratered world much like the Moon. Later images proved that conclusion to be wrong as well, with today’s images showing Mars to be a very complex and active world, with a geological history both baffling and dynamic. Even now, after a half century of improved observations, we still are unsure whether life there once existed, or even if exists today.

    Don’t want to go all dome-over-the-Earth, but what sort of weight is given to that scientist who believes there were past nuclear explosions, on Mars? (John Brandenburg)
