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.

Close-up of bright spot in Occator Crater

Vinalia Faculae in Occator Crater

Cool image time! The Dawn science team today released some new images taken by the spacecraft in its final tight orbit around the dwarf planet Ceres. The image on the right is a cropped section of the full image. It shows some interesting details of part of one of the two bright spots in Occator Crater, dubbed Vinalia Facula, and was taken from a distance of 36 miles.

Other images show small bright spots in another small crater, fractures and interesting patterns in the floor of Occator crater, a dome in Occator Crater suggestive of underground processes pushing up, and other close-ups of its crater walls.

While all of these features are reminiscent of geology on Earth, none are really the same. Ceres’ light gravity and harsh environment, plus its history in the asteroid belt, requires alien processes that only hint at similarities to what we see on Earth.

    Bob, What is the distinction between the following..

    Dwarf Planet

    I think I can figure out comet, meteor, Kuiper Belt object, is there anything I’ve left out of the menagerie?

  • Col Beaussabre: There is no consensus on the meaning of these words because the planetary science community has never accepted the very bad ruling by the IAU that tried to take planetary status away from Pluto. In general however, they consider any object with sufficient mass to have a spherical shape to be a planet, with dwarf planet assigned to smaller minor members of this group. The giant moons of Jupiter and Saturn, for instance, are considered by planetary scientists as planets. Some are bigger than Mercury.

    Asteroids are objects that are so small their shapes are irregular, like Ryugu. Meteor is what you see streaking across the sky. Meteorite is what is recovered on the ground.

    Planetesimals is a general term for all these objects, and is usually used in the context of a solar system’s early years, when it is packed with lots of objects of many sizes.

    Debris is not a technical term, but if used it usually refers to material left over from an impact.

    I hope that helps.

    Mr. Z.,
    I’d add in “meteoroid,” for Col Beausabre’s list as well. [ that which from open space becomes a meteor in the atmosphere and then a meteorite on the ground ]

    Q: Do “they” really consider the moon’s of Jupiter & Saturn, to be “planets?”
    I was under the assumption, “that which orbits a planet, is a moon.”

  • wayne: Of course they are moons. But when a scientist looks at an object that large and complex, they can’t but help use the world planet to describe it also.

  • Col Beausabre

    Thank you, gentlemen! I am now enlightened….
