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.

The cost of launch

Two news items from NASA today:

What I find most interesting about these stories is the fees charged by the two companies. SpaceX will be paid $82 million for its one launch, while ULA will be paid $412 million for its three launches, or about $137 million per launch.

There many factors influencing the cost of a rocket launch. For example, SMAP, OCO-2, and JPSS-1 might be heavier than Jason-3 and would thus require a more powerful launch vehicle. This would increase the launch cost. (Though in this case this probably doesn’t apply. The Delta 2 generally appears to put less payload into orbit than Falcon 9, though because there are many variants of the Delta 2, this comparison might not be valid for these particular launches.)

Moreover, it isn’t just cost that determines the choice of a launch vehicle. NASA has had two previous failures trying to get an OCO (Orbiting Carbon Observatory) into orbit, using the newer and cheaper Taurus rocket from Orbital Sciences. The agency probably decided after two failures it was worth spending some extra money to get a proven rocket that could be trusted to work on the third try.

Nonetheless, on their face these numbers show the Falcon 9 to be about 35% cheaper to use than the Delta 2. At these prices, it is going to be increasingly difficult for other rocket companies to compete with SpaceX, unless they somehow lower their costs. It is probably for this reason that the European Space Agency appears to be reviewing how it builds its rockets. Similarly, ULA will have increasing problems in future years selling the Delta 2 unless it can make it more competitive with Falcon 9, as will the Russians, Indians, Chinese, and all other American rocket companies.

As I like to say, the competition is heating up. And the best part of this battle is that it is going to force downward the price of getting payloads into orbit, the result of which will be that space and its exploration will become more accessible to everyone. With lower costs will come more customers. More customers will increase demand, which might cause the prices to go up but in this case is more likely to encourage the appearance of new launch companies, all striving to win that increasing customer base with competitive and cheaper launch costs. And these lower costs will once again increase the customer base, which will once again encourage more companies to enter the market, which will once again lower the cost and increase the customer base. Etc, etc.

Eventually this competition and the lowering of costs — more than any other innovation or government action — will make space travel routine.

And to that I say, “Amen! Hallelujah!”

    There are other reasons for the costs to vary. These are primarily the integration of the payload. These include: payload processing; launch vehicle integration; mission unique launch site ground support; and tracking, data and telemetry services.

    It is hard to know what percentage of the total cost these comprise, but they are significant and vary with the type and complexity of the payload.

    The last time I checked Space X was still listing the cost of a Falcon 9 launch as $54 million. It was not clear whether the payload integration services were included. Making the assumption (and it is a big one) that the $54 million figure is an accurate one for launch of Falcon 9 only that would mean that the $82 million includes $28 million integration services (about 34% of total launch cost).

    To know how launch prices would actually compare you would have to have much more detailed information about the respective satellites.
