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.

Virgin Galactic lawsuit against Firefly moves forward

Virgin Galactic last week moved forward aggressively in its lawsuit against Firefly Space Systems, its officers, and its business partners for using stealing trade secrets.

According to the Complaint, Galactic hired Markusic in 2011 as its VP of Propulsion. Markusic’s role gave him intimate knowledge of the Company’s research into liquid rocket propulsion, space vehicle architecture, “aerospike” technology, and other confidential projects. While still employed at Galactic, Markusic allegedly solicited business partners and founded Firefly based on concepts and data he obtained in the course of his work. Galactic maintains that Markusic and Firefly relied on and continues to use the Company’s technical and marketing information, as well as Markusic’s engineering notes from his tenure at Galactic, to develop products such as a recently announced small launch vehicle.

The worst thing about this court battle to me is that if Virgin Galactic has developed worthwhile technology in connection with the aerospike engine, they have done nothing to develop it, and are now acting to squelch someone else’s effort.

    They’ve already effectively closed Firefly. What are they trying to do now? Make the rubble bounce?

  • Tom Billings

    This seems more than a bit punitive, to the point of seeking to “teach a lesson” to others in the field, since Firefly is no longer competitive. That is an unwelcome development. It is truly strange that a company focused on pursuing SpaceShip2 in 2013 would be working on aerospikes at all, and even more so that having decided not to pursue them, they are trying to keep others from doing so. It’s not like others have not flown these sorts of engines in the recent past, after long labors of their own.

    George Whitesides did not show this level of vindictiveness in any association we have had with him. I am wondering about Mr. Branson, however. Is there a claim of some specific improvement being stolen that is truly worthwhile, …or is Branson saying that “if *I* ever paid you to work on aerospikes, you cannot work on aerospikes for anyone else”???

    This is starting to remind me of the Wright Brothers. They invented the airplane and three axis control, then spent the next several years defending their patents instead of continuing to advance the state of the art. But then again, the Wrights had been shopkeepers, not inventors, so it is hard to say how much additional ingenuity was left in them.

    Virgin Galactic may end up doing the same thing, except without the patents to defend. The heritage Virgin companies are not engineering companies but provide services to the general public. Virgin may not have a lot of ingenuity or much incentive to develop the aerospike engine.

    It is hard to say what is proprietary to Virgin, what they innovated themselves, but I wonder whether this lawsuit is merely sour grapes that Markusic left to start his own company, working on the same type of engine (as Tom Billings just suggested).

    According to Firefly’s website, Markusic is already well versed in rocketry, having been “Principal Propulsion Engineer at SpaceX” as well as a lifelong propulsion engineer, so it is difficult to know what he may have learned at Virgin or why Virgin thinks that he is using their proprietary information.

    The advantage to the arbitration and disadvantage of the courts is that in the courts the proprietary information may end up becoming public knowledge.
