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.

Movie of Perseverance’s descent and landing

Cool movie time! The science team for Perseverance today released movie footage obtained by the rover as it descended and landed on Mars in Jezero Crater. That video is embedded below.

If you compare what this movie sees with the orbital images from Mars Reconnaissance Orbiter (MRO) that I posted earlier today, you can recognize the features in the crater and anticipate exactly where the rover is going to land.

    That is a very cool video. I noticed the washboard features across the terrain at 1m58s. Such detail during descent and I did not mind the wobbling!

  • t-dub

    Amazing to watch! Interesting that when the parachute deployed that they lost a radome protecting an antenna but since it was on the descent stage it doesn’t really matter as it is crashed on the surface now anyways. It was also interesting to see that one spring that came loose on the heat shield. The microphone sounds of the Martian wind were cool, can’t wait to hear more sounds later of equipment on the rover working.

    Honestly not sure why it bothers me but it seems like they should wait to start clapping until they have touch down. All the other clapping seems really empty could just be replaced with finger snaps…

    In any case cool video its honestly insane we can make this happen

    Excellent video. You may enjoy the shot-by-shot commentary about this video at about 16 minutes into this live stream:

    a repeat from me–good stuff on the background of this video presentation

    So, who can tell me if all those fake “masks” the science team wears, were manufactured in china?

  • Sayomara noted: “. . . just be replaced with finger snaps…”

    From a Thelonious Monk jazz festival appearance: “Hep cats know to snap on the upbeat. Don’t snap on the downbeat; it’s considered aggressive.”
