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.

Rocket Lab to recover 1st stage on next flight

Capitalism in space: Rocket Lab yesterday announced that in its continuing program to make the first stage of its Electron rocket reusable, it will attempt to recover the stage after splashdown in the ocean during its next launch in May.

While Electron’s second stage delivers the satellites to orbit, Electron’s first stage will undertake a series of complex maneuvers designed to enable the stage to survive the extreme heat and forces of atmospheric re-entry on the way back to Earth.

As the rocket reaches speeds of around eight times the speed of sound on its descent, the air around Electron heats up to 2,400 °C generating an extremely hot plasma that creates a red-orange glow around the re-entering stage. Because Electron will enter the atmosphere engines first, the nine 3D printed Rutherford engines on the first stage will bear the brunt of this extreme heating. To withstand the immense temperatures, this Electron features an evolved heat shield designed to protect the engines and direct the force of the plasma away from the rocket. After entering the atmosphere, Electron will deploy a drogue parachute to help begin the process of slowing the rocket down and stabilizing its descent. Once Electron is at subsonic speeds, a circular parachute is deployed to help further slow the rocket in preparation for a gentle ocean splashdown. A Rocket Lab vessel will then rendezvous with the stage in the splashdown zone, approximately 650 km from Launch Complex 1, and retrieve it for transport back to Rocket Lab’s Production Complex for inspection.

They did the same thing on the previous launch. This second test will be to validate what was learned then.

If all goes as planned, they hope the next recovery attempt will be an in-air snatch by a helicopter, before the stage hits the water. If that is successful that stage will then be capable of re-use.

    With a shroud over the engine block…hmm…have THAT as the nose of a sissor wing fly-back?

    No, they plan a third splashdown test before attempting an in-air recovery.
