On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each.

Is it snowing microbes on Enceladus?
“More than 90 jets of all sizes near Enceladus’s south pole are spraying water vapor, icy particles, and organic compounds all over the place,” says Carolyn Porco, an award-winning planetary scientist and leader of the Imaging Science team for NASA’s Cassini spacecraft. “Cassini has flown several times now through this spray and has tasted it. And we have found that aside from water and organic material, there is salt in the icy particles. The salinity is the same as that of Earth’s oceans.”

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 the Mars Society.

The House today passed the Republican 2013 budget, 228-191.
The House today passed the Republican 2013 budget, 228-191.
Ten Republicans voted no. All Democrats voted no.
Though this budget might not be perfect, at least it makes an effort to face the budget situation. Note also that the Democrats have now rejected their own President’s budget as well as the Republican budget. In addition, the Democratic leadership in the Democratically-controlled Senate has already said they won’t pass a budget this year, the fourth year in a row.
The country is sinking in debt caused by the federal government. It behooves these elected officials to deal with it. That the Democrats won’t tells us much about their lack of qualifications for office.

We must all remember this vote when the Democrats demonize any future budget proposals by the Republicans. The above vote was very bipartisan. Even the Democrats rejected Obama’s proposal.

A strange lunar crater
Lunar Reconnaissance Orbiter recently celebrated its 1000th day of imaging in orbit around the Moon, snapping images and cataloging the Moon’s geology.
Only a week before the science team posted a spectacular oblique view of Ryder Crater. The image is visible below the fold, along with a close-up of the crater’s strange hump-backed boulder-strewn floor.
