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.

New observations confirm Earth-like planet orbiting nearest star

Worlds without end: New observations have confirmed the existence of an Earth-sized planet orbiting the nearest star to our Sun, Proxima Centauri, only 4.2 light years away..

The planet, Proxima b, is estimated to have a mass 1.17 of Earth’s, and orbit the star every 11.2 days. Based on that orbit, the planet is also in the star’s habitable zone. Whether there is life there however remains unknown.

Although Proxima b is about 20 times closer to its star than the Earth is to the Sun, it receives comparable energy, so that its surface temperature could mean that water (if there is any) is in liquid form in places and might, therefore, harbour life.

Having said that, although Proxima b is an ideal candidate for biomarker research, there is still a long way to go before we can suggest that life has been able to develop on its surface. In fact, the Proxima star is an active red dwarf that bombards its planet with X rays, receiving about 400 times more than the Earth. “Is there an atmosphere that protects the planet from these deadly rays?” asks Christophe Lovis, a researcher in UNIGE’s Astronomy Department and responsible for ESPRESSO’s scientific performance and data processing. “And if this atmosphere exists, does it contain the chemical elements that promote the development of life (oxygen, for example)? How long have these favourable conditions existed? We’re going to tackle all these questions.

The research data also suggests there might be another planet in orbit around Proxima Centauri, though this conclusion is very preliminary.

    Rut roh. Alpha Ceti 6.

    Huh?
    Ceti Alpha VI, a fictional planet mentioned in Star Trek II: The Wrath of Khan?

    Every 11 days is very close to the sun, it would pass through atmosphere/solar flares easily.
    Mercury takes 88 days to go around the sun, our moon 29 days. The tidal effects alone would most likely melt the surface just like Io which orbits Jupiter every 1.76 days.

    We need to start looking for low gravity bodies with high levels of metals.

    Bodies massive enough to form themselves round and at most with 1/4 of Earths gravity.
    Bodies just large enough to make mining metals easy and with just enough gravity to make refining it easy.

    Once we can travel the stars colonies on Earth like planets are a luxury but not a necessity.

    Probably tidally locked and perhaps even molten due to tidal flexing. Don’t make vacation plans just yet.

  • Star Bird

    To find Planet X we must follow along all the planets in Alphabetical Order like plAnets A-B-C-D then we find Alpha Centari and the Jupiter 2
