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.

Cool image time! The two photos to the right show the landing site for the Perseverance rover in Jezero Crater on Mars. The first image was taken in 2016 by the high resolution camera on Mars Reconnaissance Orbiter. The second image was made available today in the monthly release of photos taken that camera on MRO.

The arrow points to a small white streak that is not visible in the 2016 photo. A closer look reveals that the streak is actually two fanlike white deposits expanding outward in opposite directions from a central point.

What we are seeing are the exhaust fans blown onto the Martian surface by the retro-jets on the Sky crane that was lowering Perseverance to the ground. The rover was put down at the centerpoint, and was still at that spot on March 2nd when this photo was acquired.

The highest resolution version of this image requires special software, so in this version you cannot see the rover itself. Nor can you see the Sky crane after it crashed landed or the parachutes.

The new photo was taken one week after the first high resolution image from MRO, as part of what will become a routine periodic monitoring of the site, along with obtaining mapping information for picking the rover’s upcoming route They will also probably use both images to try to locate both the Sky crane and parachutes, on the ground.

    Bob,
    If you open the left/new picture and expand southwest of the left large crater, on the ridge southwest of the crater at about the diameter of the crater there are 2 new bright white dots. Could these be the parachute ?

  • Dennis: Yes, that could be the parachute. It also could be a bad pixel or two. We shall have to wait for the press release, which I expect in the next few weeks.
