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 postpones Mars Dragon missions

Based on statements from one NASA official, it appears that SpaceX has put its plans to fly a Dragon capsule to Mars on “the back burner.”

Jim Green, head of NASA’s planetary science division, told Spaceflight Now in an interview that SpaceX has told the agency that it has “put Red Dragon back on the back burner.”

“We’re available to talk to Elon when he’s ready to talk to us … and we’re not pushing him in any way,” Green said. “It’s really up to him. Through the Space Act Agreement, we’d agreed to navigate to Mars, get him to the top of the atmosphere, and then it was up to him to land. That’s a pretty good deal, I think.”

It is my impression that, because NASA has forced SpaceX to give up on propulsive landing of its Dragon manned capsules, the company cannot afford to invest the time and money on it themselves, and thus do not have a method yet for landing a Dragon on Mars. Thus, they must postpone this program.

    It looks like SpaceX will probably design a SSTO lander between the size of the Dragon and the ITS. Probably optimized for using the thin martian atmosphere for horizontal flight breaking.

    Which completely destroys one chapter of the book I’m working on! Oh well.

    Space X will still have to use the dragon rocket engines for the emergency escape system.
    So they will still be used just not used as a landing system yet.

    NASA plays very safe with everything and it probably just doesn’t want to risk and returning experiments to a landing test.

    But if in the near future there is ever just a returning garbage run I bet Space X argues for a landing test.

    Or if Space X ever has a thrice flown Dragon, a Falcon 9 on its last flight and some spare time and cash……

    Unless NASA thinks its just to dangerous to have a fueled ship burn back in.

    And in that case they have to drop back to the old Apollo style needle nose system and throw away 5 million or more in parts on each trip.

    The problem with Red Dragon is that it carries too few people to offer any benefits from scaling. Launching more Red Dragons wont create scaling efficiency. It could work ok for some expensive prospecting missions but everything would be expensive enough to prevent almost anyone but government from participating.

    I am pretty far from being an engineer but it looks to me like each environment needs its own specialized vehicle. What works good for getting off Earth wont work as well in space or on Mars. It could be that in-space transportation could be the limiting factor but also once we can build vehicles large enough to carry thousands of people, will be the enabling factor.

    You’re right Wodun, but the bigger problem is the Dragon just doesn’t carry enough fuel for safely landing with little margin for error. The ITS is designed for lower per person unit cost, but it’s absolute operating cost is too high. Thus something mid-sized makes sense.

    Well, at the very least, it provides more time to include a rover in the package delivered to the Martian surface when and if it does fly.
