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.

InSight mole team reports some digging success

InSight scoop pushing against mole as it digs

A new strategy devised in February to use the scoop on the Mars InSight lander to push down on the mole digging tool so that it could gain traction and dig downward has apparently had some success.

We started about seven centimetres above the surface on Sol 458 (11 March) and we are now at the surface with the scoop on Sol 536 (30 May 30), after six cycles of hammering over 11 weeks.

If you click on the image on the right you can see a movie assembled from images taken since February as they pushed down. The mole has clearly descended into the Martian soil about seven centimeters, or about three inches. The issue now, as shown in the movie, is that the mole is now deep enough that the scoop is pressed against the ground. It can’t really push down anymore on the mole, at least in this configuration.

They have the option of using the scoop’s tip to push farther into the ground, but that involves some risk. First they plan to let the mole continue to dig, without the scoop’s help, in the hope that it is now finally deep enough into the ground that the ground is finally able to provide the friction required to hold the mole in place. If this doesn’t work, they will then try using the scoop to fill the hole up to provide more friction.

If that doesn’t work, they will then try using the scoop tip to provide the added pressure.

All in all, it does appear there is now hope that the mole will eventually get the heat sensor for measuring the internal temperatue on Mars deep enough to do its primary mission. Stay tuned!

    Dig it !

  • I would try filling the hole with dirt and use the shovel to push on the dirt, if it continues to move downward fill and repeat .

    It took the Apollo guys just a few minutes to drill an 8 foot deep hole! Of course, there‘s no need for humans when robots can do it better, cheaper, blah, blah, blah…
