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.

Planes flying at high latitudes can travel through clouds of high cosmic radiation

The uncertainty of science: Researchers have found evidence that suggests that planes flying at higher latitudes can sometimes fly through concentrated pockets of high cosmic radiation.

“We have flown radiation sensors onboard 264 research flights at altitudes as high as 17.3 km (56,700 ft) from 2013 to 2017,” says Kent Tobiska, lead author of the paper and PI of the NASA-supported program Automated Radiation Measurements for Aerospace Safety (ARMAS). “On at least six occasions, our sensors have recorded surges in ionizing radiation that we interpret as analogous to localized clouds.”

…Conventional wisdom says that dose rates should vary smoothly with latitude and longitude and the height of the aircraft. Any changes as a plane navigates airspace should be gradual. Tobiska and colleagues have found something quite different, however: Sometimes dose rates skyrocket for no apparent reason. “We were quite surprised to see this,” says Tobiska.

All of the surges they observed occurred at relatively high latitudes, well above 50 degrees in both hemispheres. One example offered in their paper is typical: On Oct 3, 2015, an NSF/NCAR research aircraft took off from southern Chile and flew south to measure the thickness of the Antarctic ice shelf. Onboard, the ARMAS flight module recorded a 2x increase in ionizing radiation for about 30 minutes while the plane flew 11 km (36,000 feet) over the Antarctic Peninsula. No solar storm was in progress. The plane did not abruptly change direction or altitude. Nevertheless, the ambient radiation environment changed sharply. Similar episodes have occurred off the coast of Washington state.

The theories proposed to explain this at the link are not very convincing, and suggest to me that they really do not know what causes this. All we do know is that it likely associated with the interaction of the Earth’s magnetic field and cosmic radiation.

    Cosmic (and Solar) rays are treated as noise when they cause dots and lines of saturated pixels in telescopes, which they always do so there’s alot of potential data about it. But I heard an interview with an astronomer who specializes on investigating cosmic rays. He complained that all of his colleagues always did their best to erase all of the data he was interested in!!! :-P

    As a captain for that airline HQ’d in Atlanta, I always tried to fly below 31,000 ft when I could. SR-71 tests done decades ago showed a huge spike in radiation levels above 31K.
    When solar storm activity was present, I tried to fly below 31K.

    Too much of that exposure over a lifetime career can be nasty. At 65, I’m as healthy as can be, and on no meds. Hopefully my precautions were not in vain.

    The BDRG instrument on Lomonosov may be seeing these phenomena as well. This is just a qualified “maybe” as my Russian is poor and I’m waiting on some papers to show up.

    By the way, the gif animations of images from Lamonosov’s ShOK cameras are just wonderful, amazing and mesmerizing.
