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.

Astronomers find unexpected comets in outer reaches of solar system

Using data from the WISE space telescope, astronomers have found that there are more comets lurking in the far reaches of the solar system than they had predicted.

Scientists found that there are about seven times more long-period comets measuring at least 0.6 miles (1 kilometer) across than had been predicted previously. They also found that long-period comets are on average up to twice as large as “Jupiter family comets,” whose orbits are shaped by Jupiter’s gravity and have periods of less than 20 years. Researchers also observed that in eight months, three to five times as many long-period comets passed by the Sun than had been predicted.

These are comets whose orbits never allow them to come close to the inner solar system, which allows them to remain puffy and large.

    Puffy and large means just full of water. Something easy to harvest way out there.

    “These are comets whose orbits never allow them to come close to the inner solar system, which allows them to remain puffy and large.”

    A list of these long period (>200 year orbit but <1000 year) comets is here.
    https://en.wikipedia.org/wiki/List_of_long-period_comets
    One can define "come close to the inner solar system" as less than the distance of the asteroid belt (~3 AU). I count ~100 of these comets with a perihelion of <3 AU out of the list of 116. 36 of the comets on this list pass less than 1 AU from the Sun.

    Thus, I do not think your statement is correct.

    The time frame of a mere 200 years seems infinitesimally short in the long time of the solar system (5 billion years), so they should have passed millions of times through the inner solar system over that period.

    Also look at this list.
    https://en.wikipedia.org/wiki/List_of_near-parabolic_comets
    One of those has an orbit period estimated to be 130,000,000 years! That one would have passes as close as 4.2 AU ~38 times over the solar system age.
