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 begins stacking Superheavy prototype for flight

Capitalism in space: It appears that the third Superheavy prototype, BN3 (Booster #3), is now being stacked and prepared for the first near-orbital flight of Starship, which SpaceX is still hoping to launch before the end of this year.

SpaceX has at least six BN3 sections – amounting to 22 rings and two of three tank domes – either completed or awaiting integration. The process of stacking BN3 began sometime in the last 7-10 days when SpaceX joined two four-ring sections – including the booster’s common dome, likely pictured above.

SpaceX has mostly completed BN3’s engine section, including a thrust dome with plumbing cutouts for a full 28 Raptor engines. Most recently, what looks like a Super Heavy fuel manifold appeared in Boca Chica. That manifold will attach to the end of a supersized Super Heavy transfer tube – also spotted in work – used to route methane through the liquid oxygen tank to fuel its Raptor engines. Fueling 28 large, high-performance Raptors is no mean feat and requires a rat’s nest of plumbing to feed them more than 15 metric tons (~30,000 lb) of propellant every second at full throttle.

Put simply, a majority of Super Heavy booster BN3’s hardware appears to be ready or almost ready for integration. The eight rings now stacked represent approximately 20% of the rocket’s full height, leaving another 30 or so rings – 54m (~180 ft) – to go.

That flight, the flight plan of which has already been submitted to the FCC, would take off from Boca Chica, circle about three-quarters of the globe, and land in the Pacific to the northwest of Hawaii. While not a full orbit, this flight would demonstrate an orbital capability while allowing for a controlled safe re-entry at a planned location, a wise approach for that first orbital attempt.

    Only Starship will make the three-quarter orbit to Hawaii. The booster will attempt a “soft landing over water” in the Gulf of Mexico. I rather expect both of these to be “learn from failure” attempts, especially for Starship attempting re-entry. There are so many firsts that all need to go right – first use of orbital launch pad, including all new GSE equipment and tanks, first flight of booster, getting 28 Raptors to play nice together, first flight of vacuum Raptors, first in-flight test of heat shielding, flight software, and if they attempt an entry burn, first attempt to keep fuel chilled during orbit. (I’m sure I left a few things out…) Fun times ahead, and I think they’re serious about trying this in July.

    Interesting, too, that we haven’t seen any further word on Starship hops. SN15 is back on a launch pad, and SN16 is ready for roll-out. But every launch puts about a week’s delay in the orbital pad construction. What will get priority here?

    Also, word has it that the Raptor production line has stepped up production to have the Raptors available on time. SpaceX has been designing production facilities at the same time as building and testing both engines and rockets. All 34 Raptors used in this flight will be expended.

    Holy Schmakrel!

    But these are very big playthings, that must be played carefully…

    Super-Heavy is what I have been waiting for.

    For years-Delta II was a crutch…a tiny bone stuck in our throats that we have spat out so that we may-at last-enjoy the main course….
