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.

All systems on Perseverance so far check out good

The Perseverance science team reported this past weekend that all systems on the rover have so far reported back and are operating as expected, including the test helicopter Ingenuity.

Some more images were sent back, all visible at the Perseverance raw image website. The most spectacular new image of Perseverance released however was one taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and posted below.

Perseverance's location in Jezero Crater

Detailed view of landing site

The photo above is reduced to post here, and gives us an oblique view of Jezero Crater. The inset shows the parachute with the rover/Sky Crane hanging from it. From the image’s caption:

[MRO] was approximately 700 kilometers (435 miles) from Perseverance at the time of the image and traveling at about 3 kilometers per second (6,750 mph). The extreme distance and high speeds of the two spacecraft were challenging conditions that required precise timing and for the Mars Reconnaissance Orbiter to both pitch upward and roll hard to the left so that Perseverance was viewable by [MRO] at just the right moment.

I have added a red dot to show the spot where the rover finally landed. Directly to the west of that dot is the large delta feature that made Jezero Crater the prime landing spot. The two overhead MRO images to the right will help my readers pick out the features in the oblique view above.

The rover’s future route to get up onto that delta will skirt its southern edge and aim for a long ramp that can be seen due south of the large crater on the delta. The distance to that ramp is several miles, so don’t expect Perseverance to reach it for at least three to four years.
