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.

Sierra Nevada reveals that its Dream Chaser engineering test vehicle survived its bad landing in weekend in reasonably good shape.

Sierra Nevada reveals that its Dream Chaser engineering test vehicle survived its bad landing this weekend in reasonably good shape.

After lining up on the runway, the spacecraft’s nose landing skid and right main landing gear deployed normally about 200 feet off the ground. But the left main gear hung up for some reason. Sirangelo said the software issued the proper commands, leading engineers to suspect a mechanical problem of some sort.

The landing gear in the test vehicle were taken from an F-5 training jet and will not be used on operational versions of the Dream Chaser.

In any case, the Dream Chaser’s flight software responded to the unbalanced load at touchdown, keeping the spacecraft’s left wing off the ground as long as possible. But it eventually came down and the craft skidded off the runway in a cloud of dust. [emphasis mine]

They should release the video. If the vehicle’s software was able to keep the vehicle stable, even as it was speeding down a runway short one wheel, this would impress people. Not releasing video of this only feeds the doubts people have.

    If the craft survived in reasonably good shape, would that also indicate it would have been a survivable crash had people been on board? If so, that might also be impressive.

    Hopefully more information and videos will be released soon. Sierra Nevada stressing this is hard work, but they can roll with the punches wpuld be more reassuring than the “nothing to see here, move along” typically given by PR flacks.

  • Click on the link. The company specifically stated that any crew would have survived, probably uninjured.

    I liked the fuzzy dice hanging from the ceiling, good luck charm? engineers being superstitious?

    They won’t be there next flight, perhaps a pair of baby shoes?
