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 dust storm goes global

Data from orbit and from Curiosity at Gale Crater confirms that the dust storm that has shut down Opportunity is now a global storm, encircling Mars.

The Martian dust storm has grown in size and is now officially a “planet-encircling” (or “global”) dust event.

Though Curiosity is on the other side of Mars from Opportunity, dust has steadily increased over it, more than doubling over the weekend. The sunlight-blocking haze, called “tau,” is now above 8.0 at Gale Crater — the highest tau the mission has ever recorded. Tau was last measured near 11 over Opportunity, thick enough that accurate measurements are no longer possible for Mars’ oldest active rover.

This will be first global storm to occur on Mars since Curiosity landed in 2012, thus giving scientists the best opportunity to study such an event.

Meanwhile, Opportunity remains silent. This does not mean it is dead, but that it doesn’t have enough sunlight to charge its batteries. It might die during this storm if the storm lasts long enough, but we won’t know one way or the other until the storm finally eases.

    This is why we need nuclear power.

    The electric universe model contends Mars global dust storms tie in with opposition of earth.

    wodun–
    nail on the head. Every probe should be powered by internal nuclear.

    –a repeat from me, but lots of good factoids contained therein:

    JPL teleconference 6-13-18

    (1:00:21)

    –Teleconference reports the “Tau” was “11.5,” and they have pictures of what the sun currently looks like from the surface.
    -Opportunity is powered by solar cells, but in the main instrument bay there are multiple small nuclear units that provide 8 watts of heat-energy to the electronics. (This is the first time I’ve heard this described, and I am unclear on specifics.)
    -“Maximum design low-temperature is -50C, maximum operating low-temp is -40C, and during this storm they expect low temps to bottom out at -37C.”

    –On the upside, from past storm experience– accumulated dust on the optics has tended to shed itself almost completely during good weather. The camera’s are finely calibrated and any remaining dust aberration can be taken out digitally in post-production.

    Orion314–
    can you give me the 5 cent tour on the “Electric Universe?”
    I see a lot of youtube stuff listed with that Topic, but I’ve never delved deeply.

  • BSJ

    Wayne,

    Plug nickel tour. In the electric universe, impact craters are formed by lightning, not impacts…

    Opportunity was designed to only last 90 days. Would have been a waste to send it with a nuclear source.

  • wayne

    BSJ-
    thank you, and…point taken.
    -just a personal preference for over-engineering. (I only play an engineer, on the interweb)
    And yes– can’t beat the lifespan!

    Yeah, some of the E-Universe stuff sounds like it makes a lot of sense. Other times, not so much!

    I checked out when I read about that part of the “theory”.

    look up thunderbolts project , on youtube , a starter for the electric universe model
