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.

India successfully completes static fire testing of rocket engine for human flights

The new colonial movement: India has successfully completed the third long duration static fire tests of its Vikas rocket engine, to be used on its planned manned space mission dubbed Gaganyaan.

[T]he Vikas engine is the workhorse liquid rocket engine powering the second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and the four strap-on stages of the Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.

Experts point out that the successful testing is necessary as the testing is part of the human rating of a rocket that was not originally designed to launch humans into space. Every space agency follows its own standards of human rating of a launch vehicle and there are no global standards. “This test is one of the critical items which need to be checked in human rating GSLV Mk-III. Semi-Cryogenic engine SE-200 which will replace Vikas is still under development and its developmental times will not match the ambitious Gaganyaan timelines. Vikas is one of the most reliable engines in the world and has proved its mettle.

If you look at PSLV, GSLV Mk-II and GSLV Mk-III missions where Vikas has been used, the burn profile or duration is approximately around 150-160s only on a typical flight. Testing its performance above its designed operational limit is essential to ensure engine reliability against any event of a mishap.

In other words, for the manned mission Vikas will have to burn for a much longer time than its normal profile. They have now successfully shown that it can handle that long burn time.
