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 completes Starship static fire test with all six engines

Capitalism in space: SpaceX today successfully completed a short static fire test of Starship prototype #20 using all six orbital engines.

Though this prototype has previously completed static fire tests, those used only two engines. This test was the first using all the engines that will fly on the spacecraft’s first orbital flight.

When that flight will occur remains uncertain. Elon Musk has said it could fly as early as this month. First however the FAA must give final approval of its environmental reassessment of SpaceX’s Boca Chica spaceport. The agency has released a preliminary draft approval, but that is not yet finalized, with no clear date on when an approval will be issued.

    Very good news!

    I don’t think we’ve seen the 33 engine test of superheavy yet. That’ll be neat.

    Scott Manley tweets an amazing point: “In theory this test article has more thrust than any single rocket in the world, there are some multicore and SRB assisted vehicles, but this is a single vehicle. No guarantee they went to full thrust on this test, but even then the lower limit is blistering.”

    “Elon Musk has said it could fly as early as this month.”

    Am I correct in assuming that they will first be doing static fire tests on SH, including one with all it’s 20+ engines?
    That will be the milestone I’m looking for. Starship has had static testing and launch tests but SH hasn’t been lit yet.

    When the StarShip separates from it’s booster, will it ignite all six motors for the push to orbit?
    Or, will it continue on just the three vacuum optimized Raptors, and de-orbit and land just using the three, sea level Raptors?
    Asking for a friend…

    Am I correct in assuming that they will first be doing static fire tests on SH, including one with all it’s 20+ engines?

    More likely a graduated series of static fires, starting with a small set of the engines, and going up from there to a firing of all of them.

    Realistically, I think we have to assume that the orbital test flight will not happen until 1Q of next year – even if the FAA works expeditiously.

  • Questioner

    Starship 20 has lost some more of heat shield tiles during this static fire (about one minute into the video).

    “When the StarShip separates from it’s booster, will it ignite all six motors for the push to orbit?”

    I’m pretty sure it will use all 6, because gravity losses outweigh the ISP loss from the sea-level engines.
