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.

Redwire successfully 3D prints ceramic parts in space

Capitalism in space: Redwire announced today that it has successfully for the first time 3D printed several ceramic parts in space on ISS.

The commercially developed in-space manufacturing facility successfully operated with full autonomy using additive stereolithography (SLA) technology and pre-ceramic resins to manufacture a single-piece ceramic turbine blisk on orbit along with a series of material test coupons. The successful manufacture of these test samples in space is an important milestone to demonstrate the proof-of-potential for CMM to produce ceramic parts that exceed the quality of turbine components made on Earth. The ceramic blisk and test coupons will be stowed and returned to Earth for analysis, aboard the SpaceX Dragon CRS-21 spacecraft. CMM, developed by Redwire subsidiary Made In Space, is the first SLA printer to operate on orbit.

The replicators of Star Trek are coming. The real ones won’t be like the ones in the television show, nor will they be used to produce food, but they are coming nonetheless. It is quite likely that the colonization of space will demand a revolution in 3D printing that will make it possible for almost all heavy industry manufacturing.
