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.

Launch abort data suggests Dragon performed “flawlessly”

A preliminary review of the data gathered during SpaceX’s launch abort test on January 19, 2020 suggests the system performed “flawlessly”.

The Crew Dragon began its launch escape maneuver at 10:31:25 a.m. EST (1531:25 GMT) — initiated by a low setting of an on-board acceleration trigger — when the Falcon 9 was traveling at a velocity around 1,200 mph (536 meters per second), according to SpaceX.

Eight SuperDraco thrusters immediately pressurized and ignited as the Falcon 9 rocket’s first stage engines were commanded to shut down as part of the abort sequence. The escape engines on the Crew Dragon produced nearly 130,000 pounds of thrust at full power. The SuperDracos performed flawlessly, SpaceX said, accelerating the capsule away from the top of the Falcon 9 at a peak acceleration of 3.3Gs. The SuperDracos accelerated the spacecraft from about 1,200 mph up to more than 1,500 mph (about 675 meters per second) in approximately seven seconds, according to SpaceX.

At this point it appears the only reason the first manned launch might be delayed a bit is if NASA decides to turn it into a long duration mission, requiring new training for the crew.

    At this point it appears the only reason the first manned launch might be delayed a bit is if NASA decides to turn it into a long duration mission, requiring new training for the crew.

    Hopefully they make that decision *immediately*, because the sooner they make it, the sooner the crew can begin the extra training.

    Some of this decision may depend on where things stand with the Starliner investigations. If the investigations really *are* (as Eric Berger’s source suggests) uncovering worrisome new problems with the thruster performance such that, whether or not they decide Boeing needs to fly the OFT again or not, the Starliner crewed flight looks more and more like getting pushed back to late in the year or worse… then maxing out the value of the crewed Dragon test flight by extending it would get some extra ooomph.

    Frustrated as I am with Boeing on many levels, I really do hope they can get Starliner flying ASAP. NASA really needs both of these vehicles in operation – the sooner, the better.

    Agreed. Both systems in operation would be huge.
    Not only because of turn around rate, but also redundancy.
