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.

First Falcon Heavy demo launch to include two used boosters

The competition heats up: SpaceX plans to use two already flown first stage boosters when it does its first demo flight of Falcon Heavy later this year.

Musk said the rocket cores for Falcon Heavy’s first flight are two to three months away from completion. He emphasized that the first launch will carry a lot of risk, and as such, SpaceX doesn’t plan to carry a valuable payload or payloads with it. “We will probably fly something really silly on Falcon Heavy because it is quite a high risk mission,” he said.

SpaceX will seek to recover all the boosters from the first Falcon Heavy flight, assuming all goes according to plan. Musk said the two side boosters would land back at Cape Canaveral Air Force Station, followed by the center core returning to a drone ship in the Atlantic.

They will also try to recover the upper stage, but are not hopeful this will succeed. The article also notes that they hope to fly an additional four used boosters in 2017. SES is eager to use them on its three scheduled flights this year.

The company has also said that the booster that was successfully reused this week will not fly again, but will instead be put on display in Florida.

    I thought that Falcon Heavy required different first stages. But that’s maybe from the cross feeding concept that has been abandoned for the time being as I understand. Having the three first stages share fuel. But pumping fuel as fast as engines burn them is hard. If they relaunch used rockets they are surely just bundled together F9s. Cool that they have the flexibility to do that!

    FH core is different for sure. From what I understand, side cores & normal F9 can be interchanged, currently with changing out the octoweb (engine mount).

    SPX could launch an internet competition suggesting filling up that “silly payload” of 50 tons to orbit. I think such an idiotic stunt might actually be a great success for promoting private space flight. What do you wanna recycle for ever and ever? For $2,000 per kilogram, how could it go wrong?
