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.

The UK launches a 3D printed airplane drone

A University of Southampton team, under a project for the Royal Navy of the United Kingdom, have built and launched an entirely 3D printed unmanned air vehicle (UAV) from a navy ship.

Produced under the institution’s Project Triangle, the Southampton University Laser Sintered Aircraft (SULSA) UAV was launched via catapult from the patrol vessel HMS Mersey, and flew over the Wyke Regis training facility near Weymouth in the south of the country to land on Chesil beach. The 5min sortie covered a range of some 500m, with the UAV carrying a small video payload to record the mission so that operators could monitor it during the flight.

SULSA measures 150cm (59in) and weighs 3kg (6.6lb), and is made via 3D printing using laser sintered nylon. The university claims that SULSA is the world’s first UAV made entirely via the technique. It consists of four separately manufactured main parts that are assembled without the need for any additional tools.

The specific achievement here is interesting, but its significance in illustrating the growing use of unmanned drones and 3D printing is more important. Very soon, a large percentage of everything we own will be built with 3D printing technology, lowering the cost while making construction easier. As for drones, they carry both positive and negative possibilities.
