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.

Ingenuity completes third flight!

Low resolution montage showing Ingenuity's third flight on Mars, April 25, 2021

Early today Ingenuity successfully completed its third flight on Mars, traveling a considerable distance north from its taken-off point and then returning almost exactly to that point, as shown by the montage of four Perseverance navigation images above.

You will want to look at the high resolution montage, as the details are much clearer. The large mountains in the background are the rim of Jezero Crater. The smaller plateau in front of these mountains and much closer is the edge of the delta that Perseverance will explore.

According to this NASA press release:

The helicopter took off at 4:31 a.m. EDT (1:31 a.m. PDT), or 12:33 p.m. local Mars time, rising 16 feet (5 meters) – the same altitude as its second flight. Then it zipped downrange 164 feet (50 meters), just over half the length of a football field, reaching a top speed of 6.6 feet per second (2 meters per second).

I have embedded below the fold video of the helicopter’s take off, flight to the north, and then return and landing, created from Perseverance images. Because the camera did not pan the helicopter moves off frame for the middle part of its flight. In the coming days I expect they will assemble a video showing the entire flight.

The fourth flight is now only days away.
