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.

Curiosity’s future travels

The Curiosity science team has released a new map showing an update of their planned route for Curiosity in the coming year or so, showing how they plan on leaving Gediz Vallis Channel after spending some time exploring the numerous geological layers exposed on its eroded surface.

The new information in this map is the route near the bottom of the image, showing more precisely the route up the canyon and then their retreat through the gap in the canyon’s western wall.

To get a better idea of what this means, I have updated my annotations on this Mars Reconnaissance Orbiter image of Gediz Vallis Channel, posted previously in my May 30, 2019 rover update.

This new route information shows that they have spent a lot of time analyzing the terrain in Gediz Valles to determine exactly where the rover can go safely, while simultaneously giving them the best science. As I have noted previously,

This is where Curiosity will be going, a deep canyon about 1,500 feet across and probably as deep, its floor a smooth series of curved layers, reminiscent of The Wave in northern Arizona. The canyon appears to show evidence of water flow down its slopes, but that is unproven.

You can see from the image that the rover will be traversing numerous layers in a very short time while in Gediz Vallis, which means they might spend a very long time there.

At the same time, it is also going to probably be at least two years before they get there. Beforehand they have two recurring slope lineae to study (the second of which is indicated by the white dot), both of which might contain evidence of underground water seeping up to the surface.

At this moment the rover, as well as all the orbiters at Mars, are about to enter solar conjunction, a period of about two weeks when communications are cut off because the Sun is between the Earth and Mars.

This happens once every two years, the last time being August 2017. Then, Curiosity had not yet climbed up onto Vera Rubin Ridge, where then spent the better part of these past two years exploring the geology there.
