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 fine collection of Rosetta images

Comet 67P/C-G

Many cool images! The Rosetta team has released a bunch of very nice images taken of Comet 67P/C-G during August when the spacecraft was flying in close. The image on the right, cropped and reduced in resolution to post here, shows the comet’s large lobe, with the narrow neck to the left. Make sure you check out the full resolution image. It was taken on August 10, 2016 from about 8 miles away, and has a resolution of less than four feet per pixel. If a person was standing there you could just see them!

What I find most fascinating is the incredible curvature of the comet’s surface. The smooth area on the left, dubbed Imhotep (images of which have been posted here previously), has several big boulders on its flat surface. If you stood there, the ground would be down and horizontal. Walk only a short distance and you quickly reach the curving horizon and that flat area would look like a steep slope dropping down behind you. Yet, the boulders do not roll down hill! Walk a short distance more and you begin to enter the neck region, with giant walls rising above you, until you start to walk up them and they become the floor!

    Make a heck of a walking tour if there was any gravity to speak of.

    Petit Prince’s world exists for real!
    If it had substantial gravity, as if it was made out of solid gold, one would still land softly on the side of the cliff one fell off from. The wall would be the new ground to stand on. I hope I live to see astronauts hoover at the moons of Mars. Milligravity will be a new experience. The universe is a weird place.

    correct me if I’m mistaken– Wikipedia has the escape-velocity listed as “roughly 1 meter/sec.”
    You could practically jump off this Comet– is that a fair statement? (I’m thinking the trouble they had actually landing the lander, without it bouncing off into space.)

    Wayne,
    Yes you could easily jump off it. Off of that P69 comet.
    From Deimos and Phobos you will need some kind of gadget to get you into (a lasting) orbit. Like a bicycle. Or a pole jumping stick.

    A recent von Karman presentation about Rosetta, not archived yet but surely some day this week.
