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.

Engineers recharge Ingenuity’s batteries on its way to Mars

Engineers have successfully completed their first in-flight maintenance recharge of the batteries on Perseverance’s small test helicopter Ingenuity.

NASA’s Ingenuity Mars Helicopter received a checkout and recharge of its power system on Friday, Aug. 7, one week into its near seven-month journey to Mars with the Perseverance rover. This marks the first time the helicopter has been powered up and its batteries have been charged in the space environment.

During the eight-hour operation, the performance of the rotorcraft’s six lithium-ion batteries was analyzed as the team brought their charge level up to 35%. The project has determined a low charge state is optimal for battery health during the cruise to Mars.

They plan to do these partial recharges about once every two weeks during the trip to Mars to keep the battery charged the optimal amount.

About a month after Perseverance has landed in February 2020, it will find a large flat area to deploy Ingenuity, then move away. The helicopter will then begin a 30 day test program to see if it will be able to fly in the very thin Martian atmosphere, only about 1% as thick as Earth’s.

    This is a fun easy to understand 16-minute video about the Mars helicopter:

    It will be interesting seeing it fly. With the highest Martian atmospheric density being equal to 115k feet on earth this will be quite an engineering accomplishment.

    I heard Jim Green say in an interview today/yesterday that the little chopper won’t fly higher than 5 feet.

    That’s the hight at which an elk could gnaw on its blades. Testing for alien life, NASA style.
