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.

Another mountain view from Curiosity

Low resolution panorama

I hope my readers won’t get tired of seeing these mountain views from Curiosity, but I can’t get enough of them.

The image above is a panorama I’ve created from six photos taken by Curiosity’s right navigation camera yesterday. The box marks the location of that spectacular outcrop I highlighted in the previous mountain view five days ago. The red dotted line shows the rover’s upcoming planned route. The white cross indicates the pavement bedrock where the science team hopes to next drill.

For scale, Navarro Mountain is rises about 400 feet from where the rover presently sits. The peak of Mount Sharp is actually not visible, blocked by its near white flank on the panorama’s left edge. That peak is still 13,000 feet higher up from where the rover presently sits.

The rise of rocks next to the words “entering Gediz Vallis” is actually only probably five to ten feet high, as it is very close to the rover.

Curiosity’s travels continue to get more and more exciting to follow.

    The terrain (Marsrain?) is getting more and more interesting – love the mountain views!

    Can’t wait for a panorama from the summit of Mount Sharp!

  • How tall are these mountains?
    I try to compare the features you highlight in your posts with Earth, just to help me relate to them. The differences between the planets are fascinating to me.

    Thanks for the rover updates and cool images. One of my daily internet stops, (after BtB – of course) is the UMSF site. The folks there have constantly amazed me with their image skills and spacecraft knowledge of the many missions to Mars, the planets and beyond. One image wizard in particular, Jan Van Driel, posts almost daily panoramas using the navigation cameras from Curiosity. This is his latest, posted yesterday (8/27/20) from Sol 3219.

    While the navcam shots are lower resolution and wider FOV, these panos give me such a feeling of “you are there”, standing next to rover and gazing out across the surface. Recently I had one of the panos on screen and while scrolling around, one of the grandsons came up and asked what I was looking at. After explaining where, how and why the Martian view was taken, he said, “That’s cool, grandpa”. I was tempted to launch into “if you study hard and do good in school, you might be able to got there one day” talk, but he ran out of the room to go pester his little brother. Again! hahaha

    Great question. distance and height would be good.

    (nicely done Supertramp tune!)

  • Jose: As I say in the post itself, Navarro is about 400 feet high, and Mt Sharp rises another 13,000 feet higher.

    The highlighted outcrop I estimate to be about 100 feet tall, give or take a bit. It sits about 100 feet away, and only looks smaller and farther away because of camera lens distortion.
