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.

An igloo on Mars?

This igloo-like design is one of the concepts being considered at NASA for the first habitats on Mars.

Normally I don’t waste time promoting these NASA concept studies, since the odds of them getting built is less than zero. However, this idea is intriguing, and probably contains within it many concepts that will be used by the first Martian habitats.

    I wouldn’t describe it as an igloo but more of a bubble. An inflatable hab. Perhaps the tag not to be removed under penalty of law except by the consumer reads “Bigelow”?

  • pzatchok

    Bigelow habs have more radiation protection than the ISS. More than enough to use their technology as an inflatable habitat for the first year.

    After the first living quarters are occupied, thinner and thus lighter cheaper inflatables could be used and then covered by rigolith.

    We cannot just drop a bunch of inflatables onto Mars and blow them up. Maybe the first small temporary one but after that the area needs prepped. It needs cleared of rocks and leveled off.
    Robots cannot be trusted with that.

    Atmospheric water extractors should be the first things dropped onto the surface. Solar powered and automated, extracting water from the air and filling tough bladders.
    We can drop as many as needed and spend years collecting water.
    Eventually the excess power from the panels could be used to help power the living quarters.

    With the first people we should also send along the first earth mover/back hoe. Use that to prep the rest of the site. It could also be used to more the heavy habitats around before they are inflated. Then used to bury the new habitats.

    I would search for a cave. Failing that, I would build a house largely of stone and inflate a bubble home inside that.

    Typical that engineers are enthralled with the technology and miss the big picture.

    Would we look at building homes on earth the same way? No. We allow property owners to decide for themselves what kind of home to build. It’s not like there is any lack of concepts.

    The focus MUST be on ownership. What good is a great design of anything if nobody gets to own it? When you look at raw land on mars the first thing you should see is real estate.

    Typical that politicians already signed a treaty guaranteeing that the land on Mars cannot be owned by anyone. Only the structures and equipment placed upon that land may be considered property.

    Fortunately, once Martians figure out that they can ignore the previously signed treaties, as in Mars belongs to Martians and not to Earthlings, then they can start to talk real estate. If they start talking about private property real estate before they get there, there may be governmental mandated agreements that anyone going to Mars will never claim any real estate for themselves, otherwise they will not be allowed to fly to Mars.

    Remember, politicians, who think they are better than the rest of us, are not our friends; they want all the power and control for themselves.

    He who occupies the land owns it.
    Unless someone sends out troops to enforce some long forgotten treaty.
    And if one country sends troops you can bet another will also just to take the other side.
