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.

Blue Origin reveals full throttle long duration test of its BE-4 engine

Capitalism in space: Jeff Bezos today revealed that Blue Origin has successfully completed a full throttle long duration test of its BE-4 engine to be used by both its New Glenn Rocket and ULA’s Vulcan rocket.

“Perfect night,” Amazon CEO Jeff Bezos, who created the Blue Origin space venture more than two decades ago, wrote in an Instagram post. “Sitting in the back of my pickup truck under the moon and stars, watching another long-duration, full-thrust hot-fire test of Blue Origin’s BE-4 engine.”

The post featured a shot of Bezos and other spectators looking on at the rising rocket plume from afar, as well as a video with closer perspectives of the firing.

The company has delivered two engines to ULA designed for ground testing, and says it will deliver soon the flight ready engines for Vulcan’s first launch later this year. Blue Origin also needs to get flight ready engines finished this year for New Glenn, which is also supposed to make it inaugural flight in ’21.

Personally, I think both Blue Origin and ULA are cutting it close. I will not be surprised if this tight schedule means that the first launches of both rockets get delayed into ’22.

Nonetheless, it is great news that the BE-4 appears to finally working as planned after what appeared to be problems for the past few years.

  • V-Man

    Even if New Glenn and Vulcan fly perfectly (not proven yet, especially the recovery part), if they can’t mass-produce the BE-4 they’re not catching up to SpaceX any time soon. Especially if the latter starts mass-producing Raptors and Spaceships alike.

  • geoffc

    @V-Man – that was my thought… Vulcan needs 2 per flight, at most 10 flights a year. New Glenn will use 5 or 7 on the first stage I think. But reusable so not that many…

    How many can they make a year?

    SpaceX Is aiming for hundreds of Raptors a year. Good job SpaceX.

  • Ray Van Dune

    I wonder if SpaceX will attempt to ramp up production to 500 or more Raptors / year in-house, or outsource to a company more accustomed to serious mass-production, such as a Japanese automaker. After all, assuming 50 Raptors per SS/SH (with spares) that is only 10 ship-sets per year.

    The question might boil down to whether it is possible to keep your design secrets from the Chinese if you outsource… or even if you don’t!

    Awe shucks, Jeffie is just a good ol’ boy, one of us, a billionaire of the People, keeping Hope & Change alive in obama’s Amerika.

  • Ray Van Dune

    I think that should be “Aw, shucks”. But Jeff would no doubt prefer “Awe, shucks”.

  • Jeff Wright

    Bezos has the money to sink into finishing M-1.. a big hydrogen engine. That’s what I want to see.

  • Diane Wilson

    Ray, SpaceX will not outsource Raptor production. Musk has been very clear that he is designing manufacturing for Raptors at the same time they design Raptor itself. They have also mass-produced Merlin engines at a rate of several hundred a year, and Starlink satellites at 120 per month. SpaceX views outsourcing as risky and as loss of control.
