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.

SpaceX discovered a lot of water inside their Dragon capsule after splashdown.

SpaceX discovered a lot of water inside their Dragon capsule after splashdown.

This has got to be fixed. Though it does not appear that any cargo inside was damaged, this is the second time this has happened. More important, it suggests that the capsule integrity cannot yet be trusted in the vacuum of space. If water can seep in, it is just as possible for atmosphere to leak out.

Keep this in mind when you read reports about SpaceX’s unveiling of their manned version of this capsule on May 29. As much as I am supportive of this company, the worst thing anyone can do is be blind to problems such as this.

    Obviously any water inside the craft is a bad thing. I’m sure they will figure this out for the next cargo launch.

    I am guessing but I can’t see this an an indication of a leak while in space. If it did leak there it would have been detected while docked at least. They don’t leave the connecting hatch open the whole time just in case there is a slow leak or even a catastrophic rupture or the cargo ship. Any drop in pressure during this closed door periods would have been noticed by gauges.

    So this has to be a leak developing during reentry or after splashdown. If it was during entry they might be able to see scorch marks indicating a leak that later let in water.
    Or they can see a busted seal when they disassemble the ship for analysis. They are so far not reusing the ships as per NASA contract.

    Or is a pressure equalization valve opening and not closing fast enough to stop water from getting in. They might have to add a water trap to the valve system to help keep any sea water from getting into the cabin. Something similar to what air compressors use now.

    Surprised the anti-SpaceX crowd hasn’t jumped all over this yet. They may be learning from past experience. I look forward to hearing from SpaceX what they learn.

    I’ve heard that inside/outside temperature difference after reentry may be a cause. If so, it shouldn’t affect space operations.
