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.

An update on Rosetta’s effort to re-establish contact with Philae

This update describes the status of the effort by the Rosetta science team to re-establish a stable communications channel with the Philae lander on the surface of Comet 67P/C-G.

Confirmed contacts between Rosetta and Philae have been made on 13, 14, 19, 20, 21, 23, and 24 June, but were intermittent during those contact periods. For example, the contact on 19 June was stable but split into two short periods of two minutes each. Conversely, the contact on 24 June started at 17:20 UT (on board Rosetta) and ran for 20 minutes, but the quality of the link was very patchy and only about 80 packets of telemetry were received. Prior to this, on Tuesday, 23 June, there was a 20-second contact, but no stable link was established and consequently no telemetry data were received.

There are many reasons why the contacts have been so intermittent, much of it related to Philae’s position on the surface. To improve things, they are carefully adjusting Rosetta’s position relative to the comet while avoiding placing the spacecraft in a position where the coma’s dust will cause problems.

    Aviation Week had an article that suggests that, despite the current difficulty in communications, the awkward landing may have an unexpected advantage:

    “It was very fortunate that we landed where we did and not out in the open, because Philae could hibernate and not get overheated when the comet moved closer to the Sun, … we will be able for the first time ever to measure a comet close to the Sun; under the original plan, this would not have been possible.”

    Too bad the primary power supply is politically correct. A reactor with solar power backup would have eliminated all of this drama.

  • J Fincannon

    Reading the story at the link, it sounds as if the batteries are still not functional, they must wait until Philae is in sunlight to get enough energy to transmit.

    Also, PeterF, they were not going to have a “reactor” on such as small spacecraft. Europe doesn’t have spacecraft reactors anyway, nor even radioisotope power supplies (the option I think you meant). Not sure it is PC related though since France has alot of nuclear reactors.
