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.

Update on SpaceX’s Super Heavy booster

Capitalism in space: According to this update on SpaceX’s Super Heavy booster, the first prototype is now stacked as two complete tank sections that only need to be welded together.

While a good amount of work still remains to weld the two halves together and connect their preinstalled plumbing and avionics runs, those tasks are largely marginal and will tweak the massive steel tower that’s now firmly in one piece. Comprised of 36 of the steel rings also used to assemble Starships, the first Super Heavy prototype – serial number BN1 – will stand roughly 67 meters (220 ft) tall from the top of its uppermost ring to the tail of its soon-to-be-installed Raptor engines.

At that height, Super Heavy BN1 is just 3 meters (~10 ft) shorter than an entire two-stage Falcon 9 or Falcon Heavy rocket – the second and third tallest operational rockets today. Of course, Super Heavy is just a booster and SpaceX says the rocket will stand at least 120m (~395 ft) tall with a Starship upper stage and spacecraft installed on top, easily making it the tallest (and likely heaviest) launch vehicle ever assembled.

The report also adds SpaceX’s confirmation that this prototype will never fly, but will be used solely for ground tests. It is the second prototype that will do the first short test hops, hopefully sometime this summer.

    Hmm…I bet Super-Heavy as an SSTO-refueled and sent to Mars-might just fit flush with the grid fins as a ramp. Smaller landers maybe using that as an elevator exhaust pit silo deal? Artwork please.

    Inside a lava hole I mean.

    My concern is how fragile these tanks must be while unpressurized. A decent gust of wind could seemingly cause major problems as I believe the rings comprising the tanks are about 4mm or so thick. I guess SpaceX will learn a lot just from moving this initial tank down the road to the launch site.
