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.

Tianwen-1 launch set for July 23rd

China has rolled out its Long March 5 rocket and is now preparing to launch its Tianwen-1 orbiter/lander/rover to Mars this coming Thursday, July 23rd, some time between 12 am and 3 am (Eastern).

A Long March 5 rocket is set for liftoff with China’s Tianwen 1 mission some time between 12 a.m. and 3 a.m. EDT (0400-0700 GMT) Thursday, according to public notices warning ships to steer clear of downrange drop zones along the launcher’s flight path.

Chinese officials have not officially publicized the launch date. Chinese state media outlets have only reported the launch is scheduled for late July or early August, and officials have not confirmed whether the launch will be broadcast live on state television.

This will be the first operational launch of the Long March 5, which has had three previous test launches, with the first two failing. The success of the December launch, as well as the May success of the related Long March 5B, made this Mars mission possible.

After achieving orbit in February 2021 and spending two months scouting the landing site, the lander will descend to the surface, bringing the rover with it. The prime landing site is Utopia Planitia, in the northern lowland plains.

    NASA has always shared explicit details of their landing techniques for Mars missions. Have the Chinese shared how Tienwen-1 will do this? Is there anything innovative in their planned approach?

    Launch, cruise, and orbital insertion at Mars are big challenges, but they only require technology China has already demonstrated at least cursory competence with. But landing softly on Mars is the tricky bit, so I’d like to know more about how they plan to do it.

  • MDN: In a nutshell, China has released very little information.

    MDN,
    Tianwen-1 (translated “Heavenly Questions-1”) is a knock-off of Spirit and Curiosity. Same landing profile. The orbiter will release the payload, there will be aerobraking and parachutes to slow it down. Parachutes are cut, retrorockets kick in, and finally an airbag is deployed for landing. A ramp is deployed and the rover rolls out.

    Sorry, I stand corrected, there is no airbag and I screwed up the names. Spirit and Opportunity, not Cusriosity, used an airbag. Here is a video of the Tianwen-1 lander tests https://www.youtube.com/watch?v=CmQkWnp0t-c
    My bad.

    Here’s hoping it doesn’t clear the tower!

    Jay:

    Thanks for the try, and the link. I have to admit it’s an impressive test rig for a rocket powered soft lander at least. Thanks for the link.

    BTW, I have to share a link to the commercial Youtube queued up with this clip. Who knows how their algorithm picked this since I haven’t been searching for detergent lately (or ever that I recall), but it is one of the funniest I’ve seen in quite awhile. I’m sure it will appeal greatly to greeniacs : )
