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.

Perseverance’s possible travel route on Mars

Perseverance's planned driving routes
Click for full image.

In touting the plans of NASA and the European Space Agency (ESA) to someday launch a rover to Jezero Crater designed to pick up the cached samples that Perseverance is going to leave behind, NASA today published the map to the right, showing Perseverance’s planned driving routes in the crater, on the large delta that poured into the crater in the past, and beyond that crater.

The yellow lines indicate Perseverance’s planned route, beginning somewhere in that red landing ellipse. The green lines indicated the many proposed landing sites and pathways the proposed follow-on sample retrieval mission can take to grab Perseverance samples.

The planned route looks like they will spend a lot of time exploring the top of delta, then will move out of the crater and to the southwest towards what had been another candidate landing site for Perseverance, now dubbed the Midway ellipse.

What route the science team will eventually take at the delta depends greatly on exactly where Perseverance lands today. We will know more in only a few hours.

    Meanwhile here in Sweden…… This Englishman has been trying to explain to his workmates quite why tonight’s proceedings are perhaps the most audacious, and indeed the most scientifically important that mankind has ever attempted… Some got why I will have a small bottle of bubbly on hand, some did not get it at all…. I am as excited about the safe landing of this mission as pretty much anything other than my football teams cup final at Wembley stadium ( it’s football, not soccer!), And the birth of my children… ( Not in that order!!) What can I say… I GET the years of effort that so many people have dedicated to this mission, I GET the potentially paradigm changing results it could return, and I GET the massive danger of failure, and I GET the hopes and dreams of so many ( including myself ) that will die if the mission fails.
    God speed Perseverance, and as an atheist, I can’t pray for success, but by God, I’m wishing for it!

    I forgot to say…. There is currently only the US and NASA that could or would even attempt a mission such as this… for the scientifically literate, or even interested community world wide, NASA is a beacon for the US. Given the recent drama in US politics, I so hope for this missions success… It can only bring us all together, something we badly need right now… As a distant European, I too love NASA!

    Happy birthday bob

    She’s down safely!

    Bubbly is open and currently being consumed, even tho it’s a school night . And I’ve never been happier to do so….. NASA has many faults, but their unmanned exploration is truly “out of this world”…. Congratulations to NASA and the USA. As the late great Carl Sagan said “humanity is the way the universe knows itself” here’s to a new era of exploration of Mars!!!

    Regarding the intended “cached samples” and their pickups.

    I get first dibs on the logo for bumper sticker and tee shirt sales:
    “Please – Cleanup after your Rover”.

    Cant wait for Ingenuity to take off!! I know its solar powered. Will the revolving rotors spin off the Martian dust, or will it too
    go the way of Oppy and possibly InSight (currently at 28% of Max.) ? What’s a safe flight radius from Perseverance? What’s its top speed?
    Will it fly? What did it cost to make?
