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.

NASA extends Chandra telescope operation to 2024

NASA has extended its contract with the Smithsonian Astrophysical Observatory in Massachusetts to run the Chandra X-ray Observatory through 2024.

In many ways the longevity of both Hubble and Chandra as well as other space telescopes has demonstrated the robustness of much in-space engineering these days. It suggests that when we finally begin building manned interplanetary spaceships we should have confidence they will operate reliably for long periods.

    Ref “It suggests that when we finally begin building manned interplanetary spaceships we should have confidence they will operate reliably for long periods.”
    — Hubble had several assemblies replaced during its life, a luxury nearly no other spacecraft has ever had. It is not a good example of long-life reliability. Other spacecraft from 15 years ago or more _have_ had excellent reliability, but they were produced when electronic parts reliability was pursued much more so than is done today.
    — I have much less confidence in long-life for assemblies produced today. Some will survive a long time – but many won’t. Similarity to a spacecraft assembly that survives very well is no guarantee, as in today’s financial environment an electronic part sold today is not necessarily the same part as sold next week, even with the identical part number.
