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: No 1st stage footage on tonight’s Starlink launch

During last night’s short broadcast leading to the abort at T-1:24 seconds of a launch of another 60 Starlink satellites, the company announced that it would not show the video feed from the reused first stage booster as it returned to Earth.

[A] SpaceX engineer revealed that the company would not be broadcasting live feeds from Falcon 9 B1049’s onboard cameras during the launch. The ambiguity of the comment made it impossible to determine if SpaceX was simply choosing to not show those views or if something was wrong with the camera downlink system, while the same engineer-turned-host did go on to state that “all systems are green” moments later.

No explanation for the sudden change – possibly the first webcast in years without live views from booster cameras – was given. Starlink-17 serves as a return-to-flight mission for SpaceX after Starlink-19’s failed landing, during which the rocket’s onboard cameras streamed what appeared to be clearly unusual and possibly off-nominal behavior early on in the landing process.

The article at the link then speculates that maybe SpaceX was worried about that booster’s ability to land (it will be flying its eighth time, same as the booster that failed on the earlier flight).

I am very skeptical of that theory, especially because SpaceX has never shown a reluctance to show the public its failures. Instead, I think SpaceX has decided to do an engineering test of that booster during its return, and for propriety reasons wants to keep this from public eyes. If so, the test itself might also mean they are willing to lose this booster during that test.

During the early days of their program to reuse boosters, they sometimes had the returning 1st stage do some very stressful maneuvers, producing very spectacular light shows when launched from Vandenberg on the California coast. It could be they want to test this older booster on its eighth flight in a similar manner, in order to reassess their engineering and thus make it possible to upgrade and extend the re-usability of later boosters.

    This might be a Starship type swan dive to test for sloshing-though that would seem less an issue for more narrow rockets.

    A Saturn IB type design would better hold legs and reduce slosh. I might have winged fly-backs designed around fork-lift servicing as strap-ons to a more rugged cluster core and boost that back. The upper stage and pay-load of another build.
